This complex design will take a while to finish!
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/
Making progress on this model, here’s a couple of time-lapse videos so far, newest at the top;
1/26 Uploaded the longer video to-day, the design progress can be especially seen near the end;
As I look around in google and flickr’s images, there’s certainly no lack of a large variety of Sullivan & Elmslie designed architectural terracotta, both pictured on building facades as well as stripped-off artifacts such as those found at the City Museum in St Louis from demolitions.
As I find interesting designs that I like and think will sell, I’ll be working on more models of these unique and interesting designs.
I’ve already identified at least two pieces I want to model next, the first one was from the same James Scoville building as the recently finished design with the webbed lotus leaf design.
The original shown below was sold at an auction site a few years ago for a whopping $11,250 plus the usual buyer’s premium which tends to add about another 20% and sales tax on top which brought the final price on this to an insane $15,000;
I’ll probably work on developing the design and starting the model of the main section of the above in the next 2-3 weeks, I may make the side pieces as well since it’s MUCH easier to make them and have them fit properly if they are done together, it would take 10 different uniquely shaped moldings for the surround, but they were nothing but flat blocks with a half-round design on the surface acting as a nice visual border.
Probably when it’s done in fired red terracotta the pricing for each main motif sans the borders will run around $325, but it will be available in interior cast stone as well. The borders will be modelled and stored away in case a client wants them, I won’t automatically just make molds of those as there may not be any interest in the border pieces.
The other design I liked is at the City Museum in St Louis MO., I once went to St Louis to visit a friend of mine there, and to exhibit at a dog show sponsored by Purina, my hotel was some distance from the show grounds on the Purina property, but I visited St Louis.
So this is a pier capital from the Washington Irving public school that was demolished in Indiana, it was about 20″ square, with an interesting repeated design. I’ll be starting a model of this soon as well. Probably when it’s done in fired red terracotta the pricing will run around $325, but it will be available in interior cast stone as well.
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!
I’ve begun the process last night to take my design towards making it in hand-pressed kiln fired terracotta, that requires two additional mold making steps, the first of which is making a rubber positive master cast using the new rubber mold, the second step is making a plaster piece-mold taken off the rubber positive.
Shown below is the rubber positive that was poured in last night- the remaining cavity not filled with that amber colored rubber will be filled with plaster to save on expensive rubber since only the face is the important portion of the design.
The amount of rubber shown in the mold was 2 gallons total, and this cost just about $200, so it’s easy to see how much it would cost to fill this the rest of the way up with this rubber!
Once this rubber is cured and the cavity filled to the top with plaster, it’s taken apart and the plaster and rubber master positive can be used to make the plaster piece mold.
This is similar to the way this was done for the originals my work is based on, though the final plaster piece molds are made identically to the way they were for these pieces back in the 19th and early 20th century when these ornaments were used on building facades.
All of the Sullivan/Elmslie designed terracotta ornaments were made exactly the way I make them- hand-pressed clay into plaster piece-molds, and then final finishing and detailing all done by hand one at a time.
The Virginia Museum of fine art which has a few artifacts from this building also has at least one of these lunettes with a very similar design on it as the spandrel panels have.
I like the shape of it as well, I have no plans to but easily could make the surrounding flat pieces for it if a client wanted them.
I will be working on this model very soon, of course it takes time and this type of work is done when I have time, and more time for the various mold making processes to get done, but progress photos will come along here soon enough.
This would most likely be priced around $325 in fired red terracotta.
The museum has their artifact sized 18-1/4″ x 18-1/2″ and 4″ deep, this size would fit into my existing kiln, so this is another design I can keep my model of full sized like the originals and offer both interior cast-stone this size but less deep to hang ON the wall, and hand-pressed terracotta which will be slightly smaller due to the shrinkage of the clay but made a nominal 3″ deep which can be additionally used outdoors in the garden or embedded into a brick or stone wall of any type.
Dankmar Adler, 1844-1900
Louis Sullivan, American, 1856 – 1924 (Architects) Northwestern Terra Cotta Co., probably modeled by, Kristian Schneider 1884-1885
A photo of the grey painted artifact in the museum which is not on public view at the museum, appears here; https://www.vmfa.museum/piction/6027262-7946023/
The artifact they have is a gift of the Metropolitan Museum of Art.
I just ordered the two gallons of pourable mold rubber I need to “convert” my “Sullivanesque” design that was recently finished- into a form I can take a plaster piece mold from for pressing terracotta into. Two gallons is not enough to fill the mold, it is only enough to pour about 1″ deep, the rest of the depth will have to be plaster to save on the costs of not having to buy two more gallons of expensive rubber.
At last the mold is finished along with the complete time lapse video for that process;
I also cast the first interior cast from the mold and gave it a weathered antiqued wash so I could get a photo.
It will be available in brick red, kiln fired terracotta as well.
To purchase a cast of this design;
I’m finished with this Sullivanesque model now and plan to start making the mold to-morrow morning. it’s moist clay, somewhat firmer than it was as it started losing moisture, but it’s still delicate and a paint brush can leave marks on the surface so I have to almost flow the first coat of rubber on rather than firmly brushing it on.
I wanted to get the mold made before it dries since as it dries and becomes completely dry the clay shrinks about 15%, and then when pressed clay copies are made those would also shrink almost that much, so the double shrinkage of about 25% would seriously reduce the final size which I want to avoid by doing hte mold while it’s still moist and nearly the same size it was when I set it up.

There will be an interior cast-stone version available first.
I had to dig out some old unfired very fragile clay models of mine from the corner in the utility room since I had to replace the sump pump hose. This model of a Louis Sullivan design I did in 2008, I’m likely going to convert it to do it in terracotta, so I left the unfired clay model out to look over and plan for that.
This was not simply molded off an existing piece, it was modelled by me in 2008 for a Chicago client’s townhouse when he couldn’t find the exact design and quantity etc he wanted, so his contractor got hold of me and the end result was the client received three concrete casts of this, in an acid stained rusty red/orange finish.
Measurements: Approx 19-1/2″ high, 19-1/2″ wide.
