craftgrrl | questions on clay etc (Reply)

i'm working on a project to make sushi out of clay.
currently i am usually just normal craft clay dunno what its called.
[i used sourdough before]

someone told me that you can buy colored clay? [i have seen them at stores but never dared to ask how it is used/dried etc] can anyone tell me what different sorts of clay they used and how it is dried/painted/perpared [watever]

if using paint...wat sort? wat about finish?

back home i had purchased a sorta clay that after drying [in air] becomes erasers..does anyone know what it is called? it was really fun to use but i havent seen it around at all.

p.s i tried using chocolate but it doesnt mold well so i had to give up but i will try it again after buying those colored chocolates u guys told me abt. oh yah one more thing, i'm actually sorta cheating cos i have a mold for the "rice" bit. my mum gave it to me before i left home. its for making real sushi [for ppl who dunno how to mold the rice] but it's great as a mold for chocolate [or anything else] as well!
