Remnants of aluminum have been known to make bronze get too viscous to pour properly. Etc. I have one for aluminum and another for copper alloys, but I know that aluminum bronze and silicon bronze probably should not be used in the same crucible as I have been doing. When my budget allows, I'll get a third crucible of that same size.

Transfer crucibles are refractory-lined vessels used to transport molten aluminium. The refractory lining material depends upon the application. Desired characteristics include resistance to erosion and thermal shock, minimal heat loss of the metal being transferred, ability to reline liners, reduced maintenance time and increased safety.
During sapphire production, Al 2 O 3 - the compound that is to become the future single crystal - is melted in molybdenum and tungsten crucibles. It is in the Kyropoulos process that our pressed-sintered crucibles show their strengths to best effect. They are repeatedly heated to more than 2000°C (3632 °F) and then cooled down again.
Crucible's roots trace back to 1776, when the Naylor and Sanderson Steel Mill was established in Sheffield, England. A century later, the company – then known as Sanderson Brothers - was exporting increasing quantities of tool steel to America and it was decided to establish a steelmaking plant in Syracuse, New York.

So incorrect Ramp levels can definitely cause crucible cracking. The second reason is much easier - the user shuts the power supply off or has a very short ramp down time for power after the deposition is done. This causes the rapid solidification of the melt, and this stresses out the crucible liner.
Crucible shanks are foundry tools used to hold the crucible of molten metal while pouring the molds. Shanks are made in two standard designs - the one man Hand Shank and the two-man Single End Shank. Crucible rings are die formed to shape and size, insuring correct fit
