Jim.... I was curious if you were replacing your moly or just adding a new one to your capacity?

My schedule for insulation starting at the bottom was 3 inches Insblock, 2 layers of 2300 F soft brick, one layer of hardbrick, 3 inches of cast mizzou. I think this was similar to a noted furnace builders schedule circa late 80s. I think his schedule used 1800 F brick for the lower level of soft brick which would make sense because they are better insulators I believe. I used the 2300 F softbrick because I had salvaged them.

Where my crucible sets I believe I made solid all the way down on the recommendation of a friend whose pot tipped over when the softbricks dissolved after a leak.
