The tile in the dental stone is indeed an easy process.  I get my tile from
Home Depot in 1'x2' sheets for about $6 a sheet. The dental stone has a
working time of about 5 minutes or less and it is hard enough to start
gental grinding only 1/2 hour after you start mixing the stuff.  An hour is
enough to insure that it is up to almost full strength and waiting any
longer is just futzing about. Thanks, Mark, for commenting on how easy it
is. Bob May
