Iv recently got some last years im trying to run and for the life of me I can’t figure it out. In the past we ran some very disappointing material without problems but for some reason this material will not crumble. It leaves me with a very goopy end product that if I leave in the oven for weeks will grow crystals but in the past I was able to pour, put in oven without vac, and come back to crumble in 12-14 hours.
we use preform, silica, and alumina for media and N Butane for gas.
ANY guidance is appreciated very much.
