In My first pot, I promised a post about the soap dishes I extruded. The extruder-die was presented earlier in 3D-printed clay-extruder die.
Here is another picture of the extruder die that I designed and made.
The soap dishes did shrink as expected. I had designed for 80mm wide soap dishes after 12% shrinkage, and the soap dishes are about 80–82mm wide, so the design was about right.
I made four of soap dishes from the extrusion, but only three were trimmed, bisque-fired, and glazed in time for last week’s glaze firing.
Here is a view of the tops of the soap dishes.
And here is the view from the bottom—you can see that I did a really sloppy job of applying the wax resist to the feet.
Here is the top of the cracked soap dish I was emulating, side-by-side with one of the new dishes. The original did not glaze the ribs, which seems to be a necessary feature—the glazed ribs are too slippery to hold the soap well.
Here are the bottoms of the old and the new soap dishes, showing the difference between a skilled person and a rank amateur.
The scaled-down soap dishes are a little too thin and warped a bit in the kiln. (This is the worst-warped of the three.)
The end of this dish shows how sloppy I was with the wax resist. I hope I did a better job on the 4th soap dish.
Although the soap dishes are the size they were designed to be and are about as big as I can make them with the 4″ round extruder, they are really too small for bath-sized soap bars. The outer width is 80–82mm, and the widest bar of soap that could fit on them is only about 63mm. The lengths of the soap dishes are about 82mm, 91mm, and 92mm in the center and about 91mm, 100mm, and 100mm on the outer rims.
The soap dishes were made of Bravo Buff clay from Clay Planet. I glazed the soap dishes with two dips—first in shiny, milky white, then in noxema blue. The tongs left marks in the middle of each soap dish. In the last 2 photos, you can see the monogram stamp mark, as the glaze filled in the stamp area making it darker.
I don’t think that these soap dishes were very successful, but it was interesting making them. I might try to make a die for the square extruder that could duplicate the original soap dish better, but I want to play around with hollow extrusion some first, and I also want to spend some time trying to do wheel throwing, so I don’t think I’ll get around to a bigger soap dish in this set of classes.
