dauvit asked me about using horizontal centrifuge for platinum
casting, i sent a reply to the list but it got lost somewhere. alan
revere has since responded.
a few years ago while taking another class, i picked the brain of
ed friedman, the platinum instructor at revere. i have been able to
successfully cast platinum from that brain picking session.
alan, this question is for you: at that time propane was being
used to melt the platinum. because i read and had experienced that
propane can cause micro porosity in platinum melts, i wanted to use
hydrogen. i bought the neccessary regulators and leased a tank that
holds 80 cubic feet of hydrogen. this amount of fuel lasted only
for about 20 melts. has this been the experience with hydrogen at
the academy? i’ve been using the same regulator settings as i did
still using propane in beautiful ventura, ca.
please say hi to (don’t call me master) ed.
