Gold annealing crucibles GAP-35

Porcelain Gold annealing crucibles GAP-35 – 35mm Diameter, 32mm Height

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 and for ignition of precipitates such a barium sulphate and copper sulphide.

These crucibles are suitable to work under ISO11426.
