Sintering Refractory Ballast - Magic Black Powder

1kg

Use: Refractory ballast for firing Copper and Bronze Filamet™ materials in an open environment kiln

Mix Magic Black Powder with water, then place the print in the mixture, ensuring the entire print and all surfaces are completely covered and any protruding areas are fully supported. The print must be fully surrounded by the refractory. Complete firing instructions can be found on our website.

Copper and Bronze Filamet™ may be fired in an oxygen-free environment. In this case, use Powdered Graphite and/or AI₂O₃ to support the print's shape. See chart below.
