You might be able to get it cheaper in bulk if you buy it at the hardware store (polyester resin for fiberglass). Also, in the original post the poster was talking about melting plastics. The plastics being discussed by everyone else are thermosets, which means they don't melt. The Tg is more a measure of where they degrade, not a melting temperature as with thermoplastics such as polyethylene. Sounds like other people here are more expert at this stuff than me, so correct me if that's wrong. I got a B in my polymers class :( -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY! [EE]:,[OT]: ->Other [BUY]:,[AD]: ->Ads
