ComposiMold Used 3lbs Reusable Mold Making

What is the approximate volume (in cubic inches) that 3lbs of Composimold will fill when melted?

what is the melting point of this ComposiMold? can I cast candle wax(melts@200*400*)carving wax with it? I do lost wax casting for silver casting.

Can I use liquid latex with a mold made from this or would it adhere to the mold?

What does it come in? Bag or the tub like in the picture?
