I suppose that this has been a long time coming: This is Castilene cast from a plastic Sugar Skull mold. I have since started experimenting with hot sculpting to bring out the details and correct some issues. I used 91% Isopropyl alcohol in my spirit lamp, which I am guessing is the reason that my tools got so blackened. Now my wax skull has some soot all over it. Can anyone offer some tips? Is it possible to polish off the soot? Would Ethyl alcohol work better? (I haven't been able to get proper denatured alcohol yet.) I would appreciate any advice, but I also want to invoke @Robert DeCastro for his inspiration for taking the sculpting plunge.
