Hi all,
We are trying to build a muffle furnace for cupellation.
All the refractory materials are covered.
We are now trying to figure out the maths for the elements so we can get to the right temperature.
These Kanthal A1 elements should work for this project.

The inner chamber dimensions : 24" large x 24" deep x 16" high.
We want the temperature to reach up to 1400 C even if we will mainly work in the 1200 C range.
We have single phase and 3 phase in the shop.
