Thanks Gene! I have used both potassium perchlorate (KClO4) and calcium sulphate (eg drywall, plaster of paris or gypsum). Drywall is much more readily available and safer to handle (KClO4 is a carcinogen). It is a really interesting reaction - it is like Thermite in slow motion. Here is what the alumina (slag) looked like about 20 minutes after starting the titanium reaction: <http://openosx.com/hotspring/my-magma.jpg> Best, Jeshua Lacock Founder/Programmer 3DTOPO Incorporated <http://3DTOPO.com> Phone: 208.462.4171 ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
