Dear Sirs
Hi I am looking for some info on glass molds for blowing.
I work for a large Lamp Co in Miami Fl one of our dept is a glass
blowing and slumping.Myself I only know a little about glass as my
background is mold making ceramic, silicone and the like. Even thou I
helped set up the glass dept and build the glass tanks and use to
charge the glass at night before leaving that is about as far as my
knowledge goes. When we first started to do glass we were melting
marbles in side our ceramic kilns. I was making the one use waste molds
for the glass out of plaster EPK and vermiculite some one found the mix
in a glass book. That guy is long gone and I don't have the formula
any more it has been like 9 years since we needed molds like that. The
glass dept moved on to machined Graphite molds and metal molds. So my
hands have been out of the glass for around 6 years.
Do you have any idea were I can find the formula? (plaster EPK and
vermiculite mix) Book web site or do you know of it and can please you
share it.

Next they are looking at the cost of the metal molds we have to have
made 2 to 3 thousands dollars each and they are looking to find a cheep
way to make the molds so I was ask to look for fast easy ways to make
the molds. I have some ideas and I am wondering if they will work or if
you or any one you know has tried them. All the ideas relate to glass
blowing molds. All molds will be from 1 to 4 parts.

1.Ceramic molds like used in slumping the mold will be in 3 to 4 parts.
Because of undercuts.
2.Refractory like ZerCar can it be molded and will it last for say 50
blows.
3.Plaster EPK vermiculite mold.
4.Polyurethane mixed with metal powder
5.Epoxy mixed with metal powder
6.Graphite molds is there a way for me to make mold using it. I Would
like able to pour it.
7.Do you have any ideas that may be of help.
