I do think it is something that can be done at home. The details are
in " Procedures in Experimental Physics " by Strong. Available as a
reprint for Linsay. I will look it up and post. You can also turn
solid soapstone into Steatite in a pottery kiln. Experiments at the
highschool did not work well. The piece did change, but fractured along
an impurity line. I did not see the actual experiment.

Hey, that's cool. How much pressure to compress and how much heat to

sinter, would you think? In other words, do you think it's something

that an HSM could do?
