The model is coming along nicely, it’s a pretty complex design that requires a lot of planning, but as I rough out the details in the clay there will be more time-lapse videos and photos.
I pressed the first LS2 panel today, it took 60 pounds of clay, the sculpture will need to firm up a little and dry a little before I can finish cleaning up and refining the surface details.
It takes about 2- 3 weeks of slow, careful drying of pressed clay sculptures of this size before they can be kiln fired.
The firing process in an electric kiln takes approximately 36 hours and the high quality clay I use is fired to what is known as “Cone 1”- about 2,100 degrees F which vitrifies it nicely to become harder and less porous than standard hard bricks are.
Once the sculpture was removed from the plaster mold as shown, I have to spend considerable time going over every milimeter of the surface to model-in any missing details, sharpen edges, eliminate any surface defects, mold seams etc.
Each is a signed, numbered and dated work of art.
A timelapse video of the whole process is here;
The new mold for pressing terracotta from is finally dry, it took 2 weeks in front on a box fan on high. The main base piece weighs 90#, the other 6 sections probably adds another 50# to that.
George Elmslie and Dankmar Adler’s 1884 Chicagoan James Scoville building “Sullivanesque” design is sure to be stunning in kiln fired red terracotta. There are a few originals out there, at least one is sitting in a Virginia museum, and others as well as other designs from the same building have been spotted on already sold live-auction sites after having sold for an insane $5,000- $15,000, but when people have NO lower cost options and want a particular design then they have to pay through the nose, they also have to accept whatever condition and quantity is available.
It would really suck if someone had a great design in mind for their project, but it takes 4 identical pieces and they can only find 2 at a salvage yard! That’s a common delemma whe dealing with antiques- you need 2 someone only has 1 for sale, or you find 2 but one is so damaged it’s almost unusable.
That’s where I have an advantage, because if a client needs 4 of these or 44 of them, they could have them, and at a far more reasonable cost! At this time the interior-cast stone version of this panel is priced at $229, shipped to any of the lower 48 states;SIZE: Nominal 21-1/4″ high by 13″ wide, 3″ deep.
WEIGHT: Nominal #35
When these are pressed from terracotta, due to clay shrinkage, the fired terracotta version will be slightly smaller- approx 10-15%, so those will wind up around 19″ high and 11-1/2″ wide which will be a nice residential scaled sculpture that can be displayed indoors or outdoors, it can be embedded into a brick, concrete or stone wall.I expect the terracotta version will probably be priced around $329https://www.urbansculptures.com/cart/product/sullivanesque-panel-after-james-w-scoville-chicago-nr-ls-2/
To-day I started the process on the Washington Irving school, once at 4727 Pine St., Hammond Ind W1 pier capital model.
I happened to find photos of this interesting 1936 George Elmslie/Louis Sullivan “Sullivanesque” style design at the City Museum in St Louis and decided to create a model of it. I was able to scale the size of the original terracotta artifacts to about 20″ square. Though the originals were actually about 20″ deep embedded into the wall as well as projecting out from the wall about 5″, I needed to modify that original configuration to a more practical one for how my clients would likely use it- hanging ON the wall, or embedded 3-4″ into a brick or stone wall, so with that end goal in mind this model is designed to do both as it will be a nominal 4″ deep.
The original pier capitals projected out from the face of the brick facade by about 5″, as a result the design on the fronts of the capitals wrapped around on the two sides, since doing that configuration would mean making my model 5″ deeper yet (9″ total) it would make it a less than useful design for how it would be used in a non pier capital display, so I will not wrap the design around the sides beyond possibly the smallest amount on the corners.
George Grant Elmslie & William Hutton- architects, and the Midland terracotta Co with modeller Albert Fritz are said to have executed the original terracotta artifacts for the school in 1936, the school was demolished in 2003.
As the description on a placard at the City Museum says- this is an outstanding example of the Louis Sullivan style of architectural ornament. The Art Deco inspired chevron or “V” is surrounded by thistle leaves and is sprouting leaves of a plant or bud of a flower. The flower which made up of seeds emerges from the plant stalk.
In looking at the design itself, I noticed this curiosity which I circled in red;
The modeller, said to be Fritz Albert, obviously left that little square of material in the center of both larger squares, in actual modelling practice the easiest way to scribe or cut those vertical and horizontal cross lines would be to make one motion top to bottom and left to right with a tool, but Fritz didn’t do that, instead, he made four cuts to leave that little center intact, the question is why?
It’s almost as if it’s a deliberate miniature version of one of the four larger squares, but since the Elmslie/Sullivanesque designs were all based on styled organic plant forms and geometric shapes, it may be the four squares and center square are an Art Deco inspired styled four petal flower and bud.
Since none of those involved are alive to ask, we can only guess, but it makes sense.
The plaster-piece mold for this is done, waiting for the last section to set before taking it apart, and finishing up the last segment of a time-lapse video of it.
It took 125# of plaster and some 7 gallons of water, about half of that water will evaporate out.
It will be probably 2 weeks with fans blowing on it to dry it out enough to use for pressing the clay into.
This is exactly how the working molds were made for all of the Elmslie “Sullivaesque” terracotta, and all of the similar architectural terracotta as well.
About the biggest difference between then and now is only in my using a rubber positive copy instead of taking this plaster mold directly off the original clay model. With the rubber positive I could make additional or replacement molds from that whereas the clay original master is typically destroyed in the process.
Back in the old days these kinds of designs were typically custom made for each building job, so they tended to only need a few of each, a dozen maybe. If they made terracotta cornices and windowsills, these were typically made by extruding the clay thru a die under mechanical pressure for small ones, for larger ones they used a system of running a template along the clay which was the same way they did the elaborate plaster ceiling crown moldings- shaped in place using wood runner strips and templates.
I printed out the two full sized reference images I need for the two planned models, a tape measure opened to 24″ is for visually scaling the sizes in the image.
The one on the right is a W-1 pier capital design from the Washington Irving school, Hammond Indiana, the one on the left is a lunette design from the James Scoville building in Chicago.
The Scoville lunette is from an assembly of two that were sold at an auction outfit for some $15,000, while the pier capital from the 1936 Hammond Indiana school was designed by George Grant Elmslie and William Hutton in the Sullivanesque style by Louis Sullivan. The school was demolished in 2003 and this particulat artifact resides at the city museum in St Louis. I found some great photos of it that were taken by a photographer on a photo sharing site, after I inquired about the artifact’s dimensions he very generously uploaded 109 photos to an album for me to download and see, the 109 photos were all taken of artifacts in the city museum’s collection of Elmslie/Sullivanesque artifacts and others, a real treasure trove and there’s other designs I like that I may also make models of at a later date.
The pier capital will require a little thought as it was originally a 20″ cube, with all but about 5″ of it embedded into the brick wall, the sides of it that were visible had the same triangular designs as the face does, so that presents a couple of issues to decide on, for the interior cast stone the casts dont need to be deep as they would hang ON the wall, but I plan to do these in terracotta and those could be embedded INTO a wall, so if I retain the original configuration of the sides having a design instead of being flat, then I would have to make this considerably deeper- say 7-8″ deep so about 4-5″ can project out while 3-4″ would be embedded, we’ll see what I decide on that, meanwhile I will probably start the Scoville Lunette model first.
With the plaster backing done for the rubber positive I made yesterday, I removed the assembly from the rubber mold. Once the plaster backing on this master positive is soaped up well, I can make the plaster piece-mold of this for pressing the terracotta into, The piece mold will be made in at least 5 pieces, most likely about 8 pieces.
It won’t happen very soon as I used up the very last bag of pottery plaster I had on hand and I’ll have to order more along with some other materials and I need some more clay, but I don’t want to order clay when it’s below freezing, so I may order the clay in the spring and order the plaster and other stuff I need now- soon!
