That's my impression as well. A typical firing temperature for bricks
is 1800 °F, whereas I need graphite because regular Aluminum Oxide
fire bricks melt at the > 3000 °F temperatures that I will be
generating. So Unilock probably doesn't use graphite bricks. I do
have a fire brick from S & S pottery supplies that I'll use for my
first test run, I'm researching graphite because the fire brick
probably won't hold up.
