Fireclay Annealing Cups / gold annealing crucibles possess a smooth unglazed surface and thin walls. These provide them with excellent resistance against thermal shock.
Furthermore, they have a tronco-conical form designed for gold bead annealing (after the partition with concentrated nitric acid) and for ignition of precipitates such a barium sulphate and copper sulphide.
These gold annealing crucibles are suitable to work under ISO11426.
