Soap carving for casting

How to carve a bar of soap into a smaller soap shape. Discussion of various tools that can be used for this purpose. A little silliness - the carving I made is a kind of slug thing - I'm going to cast it in plastic and glue one googly eye to the upturning end. See the flat part?

Step 1: Outline the basic shape

Draw a side elevation of the shape you'll carve on the side of the soap. Starting with 2-D on one side of the block is a good way to start thinking in 3-D.

I love this idea. Please please add your casting instructable - I'm dying to know how you do it!

I keep saying this... i really will write the casting one, I just need time! Poke me about it again if you think of it.

I would think that the heat of melted plastic would melt the soap. Is this a different kind of soap or am I wrong?

Sorry I just noticed this question! The plastic isn't melted, actually. It's made like epoxy, from two liquid components, which react chemically to create the finished plastic. There is heat involved in the reaction, but not more than (I'm guessing) about 100F. This will be clearer when I do the casting Instructable, I'm hoping to get to that this weekend as I've done enough work with this now that I am starting to get castings that actually look like the model!
