Several years ago the son of Arthur McMichael, the entrepreneur who developed the Northern Clay Company (later to become Gladding McBean) allowed us to copy his father’s scrap book of company photos.They detail the process in glorious black and white images, and are featured in our exhibit.About that time the sketch books of sculptor Louis Schubert were donated to our collection. Schubert lived in Seattle and rode the electric Interurban to Auburn, sketching during his commute. Bob Mitchell discovered our museum via the web.A search engine directed him to our archive of newsletter articles that include one on the Northern Clay Company. His first hand knowledge of and respect for architectural terra-cotta completes this story. Become one of those in the know, read on and see if you don’t end up feeling just a bit smug also. —Patricia Cosgrove Terra-cotta ornamentation on Seattle Group Health building.

Terra-cotta at Seattle’s Pacific Lincoln Mercury dealership. Continued from page1 H ave you ever used the term, “architectural terra-cotta” in a conversation? Well, join the crowd; to most people terra-cotta is something that expensive flower pots are made of. Some people may have even heard of the Qin Terra-cotta Warriors from Emperor Qin Shi Huang’s Mausoleum in China (circa 211-216 B.C.). Occasionally it will remind someone of a chimney pot that they saw on a chimney top in London or a tile from a Roman spa or from a visit to the ornament section of the local garden store. Architectural terra-cotta is nothing like these things, yet it is like all of these things! From Britannica Online: Terra-cotta: (Italian: “baked earth”), literally, any kind of fired clay but, in general usage, a kind of object—e.g., vessel, figure, or structural form—made from fairly coarse, porous clay that when fired, assumes a color ranging from dull ochre to red. Terracotta objects are usually left unglazed and are often of a utilitarian kind, because of their cheapness, versatility, and durability. If you are wondering what this has to do with Auburn, Seattle or Renton, that’s where the “A Look at Architectural Terra-Cotta...from a Current Perspective” comes into play. My particular experience with terra-cotta came with my first good job after moving to Seattle from Baker City, Ore. in 1972. After the usual series of happenstance jobs that one gets after dropping out of college, I found a skilled trade job as a Pointer – Caulker – Cleaner ( P.C.C.) craft worker with a Seattle masonry restoration contractor. Back then we were just called Tuckpointers, tell that to someone at a cocktail party once or twice and finally you just say that you are a mason. Anyway, the term terra-cotta entered my vocabulary shortly after becoming a masonry restoration craft worker. It only took me 33 years to discover that a great deal of the architectural terra-cotta used in the building facades that I have worked on for my entire career was manufactured in Auburn, by the Northern Clay Company Between then and now, I have worked on a great number of terracotta clad buildings in the Northwest, and I have come to appreciate the positive qualities of architectural terra-cotta as well as the short comings of the material. One of the first things that you notice about architectural terra-cotta used in building facades is the size of the pieces. Keep in mind that the material was used as the exterior walls of the original high rise buildings constructed during the industrial revolution and the building of the great cities of America. This application required the use of terra-cotta pieces bigger and heavier than flower pots or roof tiles, as well as the necessity of being weatherproof and capable of supporting immense loads. After many of America’s major cities burned to the ground because the buildings were made of timber, we started to look for something a bit less flammable. Being non-flammable and more permanent, masonry was a natural choice for a durable building material. Ordinary People, Extraordinary History 4 Architects became aware of the flexibility of terra-cotta; it could be almost anything that they could dream of. At first it was used to copy more expensive materials like granite and other natural stones. Surface glazes were developed to mimic almost any natural building material. Then architects and designers realized that glazed terra-cotta offered almost limitless opportunities to be creative and original, they could make durable art out of their buildings at small expense compared to using expensive stone carvers and artisan building trades. But alas, all good things must come to an end, and for architectural terra-cotta, the end of economical production was due to a combination of circumstances. The direst of these was the onset of the Great Depression when new construction literally came to a standstill. Secondly, the flexibility of the material became burdensome and overly expensive as designers exercised their creative gene. Largely ignored at the time, the true competitive value of terra-cotta was that a great number of large universal pieces of terra-cotta could be manufactured from a single mold. For every non-typical piece of terra-cotta needed for a building, a new one-off mold was required. Each of these molds was made by craftsmen using hand carved clay sculptures made by some of the most talented sculptors of the time. Every unique piece required a different mold and a sculpture to make the mold from. Manufacturing the molds was one of the most time and money consuming parts of terra-cotta production. Not to mention that you needed exceptionally talented workers, cheap energy to fire the kilns, a location as close to the construction site as possible (the railroad tycoons didn’t get rich hauling heavy objects cheaply) and it took a long time to move from design to finished product. Finally, as if the deck wasn’t stacked sufficiently against the terra-cotta gurus, the rapidly developing concrete construction technology, the advent of stainless steel and aluminum coupled with the abundance of cheap hydroelectric power and American mindset of “faster is better” architectural terra-cotta production was brought to its knees. Unfortunately, the use of architectural terra-cotta in new construction seems doomed to be a novelty that is only used by enlightened institutional building owners that need to get several hundred years out of their siding or by preservationists that realize that the buildings that we have inherited are not easily replaceable, not only because of the cost of manufacture, but because of the reduced capacity to manufacture the material in local markets. The up side is that there is considerable interest in preserving terracotta clad buildings nowadays rather than knocking them down and rebuilding with other materials. There also appears to be enough restoration and new work on the market to keep the limited number of architectural terra-cotta manufacturers busy enough to invest in modern equipment and maintain a skilled work force. www.wrvmuseum.org • 253-288-7433 5 Currently the two main suppliers of architectural terra-cotta in the U.S., at least that I am aware of are, Boston Valley Terra-cotta in New York (www.bostonvalley.com), and Gladding McBean in California (www.gladdingmcbean.paccoast.com). Both companies have interesting and informative web sites worth perusing. Top Seabord Building terra-cotta cornice, Seattle. Above Banana republic (was Coliseum Theater,) Seattle. Terra-cotta as a Building Material Terra-cotta is part of the family of ceramic materials. “Ceramic(s) - Made of or pertaining to fired clay.” This family covers a lot of ground and includes brick, tile, pottery, dishes, chimney flues and pots, roofing tile, sewer pipe and the list goes on. The subject of the manufacture of architectural terra-cotta has been covered in great detail and is beyond the scope of this article except to state some of the more important points. Architectural terra-cotta is generally glazed to provide weatherproofing to the bisque (body clay that makes up the structural unit) and to provide the desired finished appearance. There are generally two styles of glaze used in architectural terra-cotta: Slip glazed and what is simply referred to as glazed terra-cotta. Slip glazed terra-cotta is a finish technique where the glaze material is made from a similar clay as the body material but is watered down to a paint-like consistency and applied to the piece prior to firing. The finished pieces are usually a dark red in color, but can run from brown to black. Slip glazed terra-cotta was generally used to imitate natural stone materials (such as sandstone) and was not manufactured or used extensively in the Seattle area. Glazed terra-cotta is finished with mineral glazes that are formulated to provide a ceramic coffee mug (glassy) type of finish, but can be a matt (flat) finish as well. Glazed terra-cotta was manufactured in a great variety of colors and finishes with the most common being single opaque colors ranging from whites to tans. Vivid colors such a cobalt blues, yellows, greens, and some metallic colored glazes were occasionally used as accents in friezes, columns, cartouches, soffits, and other ornamental pieces. Multicolored glazes (mottled or speckled) were sometimes used to imitate the look of natural stone, with granite being one of the stone types most successfully imitated. King Street Station and the Olympic Tower Building, located in Seattle, are good examples of granite finish terra-cotta. One of the more misunderstood features of architectural terra-cotta is the thickness of the material. While a piece of terra-cotta can be quite large, the surface shell is generally only one and one half to two inches thick. Webs of clay are used across the hollow back of the piece as well as the perimeter, but you should visualize a typical piece as similar to an old wooden milk crate standing on its side with the bottom being the Ordinary People, Extraordinary History 6 finished face and the clay webs being the dividers that separate the milk bottles. This design made it possible to make pieces strong enough to be used in a wall system yet be light enough to be supported by the frame of the building. The thin shell design also made it possible to fire large pieces without cracking of the surface. So What’s Up With Terra-cotta Falling Down? Why do we occasionally hear about a piece of terra-cotta falling from a building façade onto a public sidewalk? Is there something inherently wrong with architectural terra-cotta as a material? Why does the City of Chicago require regular inspections of terra-cotta facades that include tapping each piece with a rubber or plastic mallet? First off, we can blame gravity! Secondly, nearly all of the failures where terra-cotta disconnects from a building and hits the sidewalk are related to faulty installation, ill conceived design, lack of maintenance and unexpected movement such as seismic activity and settlement. Since we can’t do much to ease the gravity situation, let’s talk about the other problems. Faulty Installation Architectural terra-cotta is usually attached to the structural frame of a building with some type of mechanical anchor. Larger pieces and most projections like cornices, large water tables, statuettes, spires, parapet walls and balustrades were usually individually attached to the building frame. While non-ferrous wire ties and dowels were recommended for tying pieces together and to the structure, standard steel wire, wrought iron and steel clamps were often used. The major structural supports for cornices, oriel bays, large openings such as entries and windows were by necessity made of structural steel I-Beams, C-Channels, and angle irons. The terra-cotta pieces would then be suspended from the structural steel using steel and wrought iron threaded rods, steel straps, small diameter steel rod, ferrous pipe and wires. Often times the terra-cotta was attached to structural members that had little or no corrosion protection and ferrous metals were often used when non-ferrous materials (brass, bronze and copper) would have been of adequate strength. Failures of architectural terra-cotta systems are usually caused by water damage to anchors and supports rather than the material itself. Below Terra-cotta trim on the Washington Athletic Club, Seattle. Faulty Design It is important to remember that the use and installation of architectural terra-cotta cladding was as new to the building trades of the time as high rise buildings. Protection of the anchors and built in waterproofing features (deflector flashings, weep holes, etc.) were not always as well considered as they may have been. When you consider that shrinkage of the building frame coupled with expansion of the masonry skin can vastly exceed the structural www.wrvmuseum.org • 253-288-7433 7 capability of the terra-cotta, it is not difficult to understand why the shells of some terra-cotta clad buildings fracture and fall from the structures. Above Indian head sculpture on the White Henry Stewart building, Seattle. Below Sculptor Louis Schubert poses with a magnificent terra-cotta ornament at Auburn’s Northern Clay Company, c1920. Lack of Maintenance By far the greatest damage and cause of failure of architectural terracotta systems is caused by a lack of maintenance. This issue is also a testament to the high quality and durability of well made terra-cotta. Terracotta was almost always set in place using mortar; usually lime mortars in the old days and cement based mortar in later years. Failure of the mortar joints and failure to replace missing mortar joints was and is the primary route of water intrusion into the structural anchors and hangers that support the terra-cotta. Because of the slow rate of corrosion of the structural members, damage to the structure often went undetected or was ignored until a leak into the interior of the building was noticed, or a piece of the terra-cotta fell from the building. Falling terra-cotta almost always gets the attention of the news media and the material itself usually takes the blame. Rarely is it mentioned that the building has been standing there for a hundred years without benefit of regular maintenance prior to the piece falling off. As with any structure built from any material, if water is allowed to penetrate the façade surface, bad things are sure to follow! Unexpected Movement I can’t think of any building movement that is more of a surprise than an earthquake. While all newer buildings constructed in areas of high seismic activity are designed with earth quakes in mind, most of our older buildings were not. One of the downsides to terra-cotta during an earthquake is because of the rigid nature of the material; any lateral movement, such as swaying of the frame, causes stress fractures in the mortar joints and the terra-cotta itself. After the 2001 Nisqually Earthquake, I wandered around Seattle for hours taking photos of damaged masonry buildings. As I walked around downtown, I noticed that even at seemingly undamaged buildings, pieces of mortar were laying all over the sidewalks. The fact that the mortar fell out of the joints as the building released energy from the swaying superstructure was no great surprise, but the fact that most of the missing mortar joints were simply swept up and never replaced is a little disconcerting. As I was called to inspect buildings for months after the quake, I discovered that many of the buildings I was inspecting had been damaged in previous earthquakes but were never repaired at that time either. This is the type of damage that when left un-repaired will greatly accelerate corrosion of terra-cotta structural members and cause catastrophic failures in the future. Ordinary People, Extraordinary History 8 Summary Personally, I have developed a great deal of respect for architectural terracotta and appreciate both the material and the people that manufactured it. My hope is that this article will inform and inspire interest in preserving the terra-cotta clad buildings that remain in the Puget Sound area. T here were several manufacturers of terra-cotta in the Puget Sound area in the early 1900s. While it is not always possible to discover who manufactured the terra-cotta for each building, some of the more prominent buildings have been noted in historical documents. The following listing provides information regarding the manufacture of terra-cotta for some these buildings. It is of interest to note that the Northern Clay Company of Auburn Wash., as well as most other local terra-cotta manufacturers, was assimilated into the Gladding McBean collective by the time of the Depression. The Northern Clay Company was purchased by Gladding McBean in 1925, but continued producing architectural terracotta under the Northern Clay Company banner until 1927 when it was renamed the Gladding McBean Auburn Plant. The Auburn plant was closed in 1932. The following buildings are located in Seattle unless otherwise noted: Northern Clay Company Coliseum Theatre Washington Securities Building Washington Mutual Savings Bank Telephone Building Joshua Green Building Pantages Theatre – Tacoma Fredric & Nelson Building Gladding McBean d.b.a.

We do this through careful handling, exclusion of insect pests, regulating the environment (temperature, humidity, light and pollution), and through appropriate storage strategies. It is the aim of this article to suggest methods for storage, particularly textile storage, which can be used in the home. I was inspired in my choice of topic by an object in the Museum’s collections; a beautiful and rare Muckleshoot cedar bark mat. This mat is exciting both because of its local history and because of the superb quality of the craftsmanship and materials. The mat would have been used traditionally as either a sleeping mat or a screen that divided living spaces in a communal house. When not in use, it would have been rolled. This piece was made by a skilled weaver using thin, uniform strips of the inner bark of a Western Red cedar, which were plaited in an over-under pattern. The bark is free from any knots or irregularities, and is of a quality that could not be duplicated by a modern weaver because similar materials do not exist! Unfortunately, this mat suffers from some entirely preventable Folded textiles are subjected to stress along the fold lines. This image illustrates the long-term deleterious effects of folding textiles. Thanks are due to Warren Kinggeorge, Museum Board member and Muckleshoot Indian Tribe Oral Historian, who provided valuable historical information about this mat. condition issues. At some point in the past, the mat was folded lengthwise and then again in thirds. This created pressure along the fold lines, and over time, the fibers of the mat deteriorated. Now, the mat is separated into two halves along the lengthwise fold and is severely weakened along the remaining folds. This damage could have been prevented through the use of appropriate storage methods. If you can visualize the damage to this cedar bark mat, then you can begin to understand the stresses being placed on that old antique quilt in the closet or Grandma’s wedding dress. Creases in fabric eventually weaken the fibers and become devastating breaks. Flat storage is best for textiles as it eliminates creases that can become breaks. But, flat storage takes up a lot of space and is generally not feasible for large textiles. Rolling textiles takes up less space than flat storage, and puts less stress on fibers than folding. Here in the museum, we roll most of our quilts and rugs. We start with a cardboard carpet roll and wrap it with Marvelseal 360, an aluminum foil coated with nylon on one side and polyethylene film on the other. This plastic coated foil is an important step because it serves as a barrier between the acidic cardboard and your treasured heirloom. Follow the foil barrier with a layer of acid-free tissue on which to roll your textile. If possible, roll acidfree tissue with the textile so that the layers of your textile “burrito” do not touch one another. Once Ordinary People, Extraordinary History 10 GoodNews! Tara Wins Award Quilts are shown as we store them, rolled on large tubes in the museum’s dark, cool, back room. your textile is on the roll, you may add an unbleached muslin sheet if you wish, for added protection from dust and sunlight. If folding your textile is the only available option, you can stuff crumpled up acid-free tissue along the folds to avoid sharp creases. Be sure to use acid-free tissue as commercially available acidic tissue paper can damage your textile over time. You should also re-fold it every few months making sure that the creases fall in different areas. Rolled rugs in the museum’s back room awaiting re-housing on our wall racks. As is, they benefit from rolling, but over the long term each will be damaged. It is always best to hang the rolls so that they do not flatten with the weight concentrated on the bottom. By hanging the roll, the curvature of the wrap will also stay consistent. www.wrvmuseum.org Recognizing her foresightful work matching standardized testing and lesson requirements with museum programs, the Association of King County Historical Organizations honored Tara McCauley, our Curator of Education with the 2007 Heritage Education Award.
