Hi Everyone,
I know I have been saying I'll post pics but you know how Murphy gets in the way. Well my card reader died and I had to replace it. So now I can actually get them from my camera to the computer.
I also just received $400.00 of new graphite so I thought I would go through the entire process in making a A type crucible and a cup type.
xlchainsaw got me thinking; how can we use graphite powder to our advantage in making crucibles? So I went to my local pottery supply house and talked with them, what we came up with is a #10 cone rated fireclay in powder form that I will mix with graphite. Then use a mold to form the crucible 1/2 to 3/4 in thick, then fire it at 3000+ for 1 to 2 hours and then use Epsom salt as a final covering to seal the unit.
Which leads me to building a new 3000 degree furnace.
So I may document that as well. I hope this works because graphite powder is way cheaper than graphite block. So please be patient I will will have the information from my trials posted soon.
~Eurekatake your time. im hoping to get a book on kiln designs soon. i have plenty of fireclay and a supply of firebrick. ive been thinking of a simple potters wheel?????? mix up a batch and see if i can make one but im thinking a rammed up crucible would be better.
