Quartz parting and annealing trays / baskets

Check out our quartz parting and annealing trays / baskets.

They are a direct substitute of both parting flasks, and gold annealing crucibles.

These quartz baskets are capable of withstanding:

  • Attack of concentrated nitric acid
  • High temperature necessary for annealing (up to 1000ºC)
  • Thermal shock due to very low coefficient of thermal expansion.

They are therefore suitable for simultaneously processing the two nitric acid attacks (the first with nitric acid 33%, the second with nitric acid 49%) and then go directly in the gold annealing furnace (after rincing with water).
