I have been making these soap dishes for some time now. I extrude them in a 4 inch barrel extruder-I cut my own die.
The feet and soap groves come out well. I cut them at angles and trim some feet down with a wire mud tool-I hole up about 1/2 of them and turn the ends up slightly to keep the soap scuz from spilling off ends.They sell ok with a few bars of brightly colored bar soap to show folks what they are-In the galleries they sell better next to hand made soaps. These do not sell as good as spoon rests but are easy to make
I'll post some fired photos next week when they are done.Making a die is easy with a aluminum blank die and a jewelers saw.The compression makes these soap dishes very strong.
Mark, Since your shared !!!what is the thickness of your soap dish..the center part not including the feet and ridges..love the design. My husband did a similar die for my extruder, but we think it may be too thick. It is probably 1/2 inch thick. Also, how long is each dish..do you mind emailing me at firstname.lastname@example.org
