Fancy, Schmancy Handles

Hello all,
I'm sure you are all familiar with the beautiful, fancy handles some potters
have on their pieces. I'm not talking about pitcher handles, but casserole
dishes and the like. How in the world are they done? All I can figure out is
they must come from a mold as they are too intricate to handbuild, throw or
pull. If they are from a mold, does anyone know who sells these molds? I
suspect these very talented potters probably make their own since I can't
recall ever seeing two potters using the same handles.
Thanks, Gaye
