Thanks Frosty! Great to receive an early reply reply on this forum. The community of small scale ceramic shell casters is very very small in comparison to you folks. I will look into water ceramic fiber and focus on alternate means for stabilizing empty ceramic shells in readiness to receiving molten metal. BTW, the shells are by necessity very hot prior to receiving poured metal.
lATER ! Maybe we are still on at the same time. Good that there is another caster on the forum. By stabilization I mean keeping in physical position. The professional caster you referenced is using a means I have seen by video used in industrial settings. It’s highly dramatic! Worker literally removes by gloved hands and wearing super PPE clothing a red hot burned out ceramic shell and fairly physically implants it into a sand bed ready for receiving pored metal. Curious how the professional caster on forum heats up sand. I do have a weed burner powered by propane.
Some comments if there are other ceramic shell casters on the forum: 1. Many as I will, are now using a hot water bath (turkey roaster) as a means for wax removal. Reported results are for much less or no shell cracking, good wax retrieval and being environmentally safer 2. For small operations automated slurry stirring is no longer necessary with new slurry formations from Remet and Ranson and Randolph (suspendaslurry). Monthly stirrings are sufficient.
