Once again we are turning to you again to lend us a hand to find for
us a firm who could supply us with a cylindrical open furnace
container made of refractory mortar which can withstand heat above
the 2000 degrees F. As you are all aware, we use this type of
furnace to molten metal where the latter is placed in a graphite
crucible and then in the cylindrical furnace, the traditional type
of melting metal, and then a propane flame is applied on the side of
it. Any help is mostly appreciated. Thank you.
