55x100 worked just fine. Dry it out first, obviously. This worked perfect for refining lithium using lithium chloride + potassium chloride mix. I did heat test this at 2012F a few times in the electric kiln. This isn't the most pure alumina material, so it wont take thermal shock like the best but you get what you pay for. It's great because it's non-conductive and easy to clean, unlike graphite types. It's the best for pouring larger gold ingots/molds. I cut a custom piece of soft firebrick to sit under this in my electric kiln, since it's short, using a bandsaw for the cylinder shape seat.
