Investment Casting question

To any investment casters out there,

Does anyone know of a material that can be used for patterns or samples
that is very runny (like water), that sets up in a very quick time, has
very little if any shrink, and has a low ash content so it can be burned
out of an investment mold? We have tried several kinds of wax, and has
been working fine, however in order to get the wax to a very runny state,
we must heat it up considerably, which causes the wax to loose some of its
properties. We want a material that will be able to pick up very fine detail.

thanks in advance,
