Has anyone tried agar or agarose? If it works, it has some nice properties
of melting and gelling. It requires boiling to melt, but it is free flowing
down to a relatively warm temperature. It then becomes hard to remelt at
low temperatures. It may be good for POP, and chemical processes, but lousy
for dichromate type processes.

Polyacrylamide is also interesting, but the monomer is a nasty toxic.
