Use for coating kiln shelves or moulds prior to fusing or slumping glass.
Each batch is kiln-tested to ensure consistency from run to run.
Illustrated instructions are included, detailing application, drying, mixing, precautions, and storage.
One 400g jar will coat about 30 50cm sq shelves.
One 2.27kg bucket will coat about 150 50cm sq shelves
One 18kg bucket will coat about 1200 50cm sq shelves
You can fire it to 260C and hold for 20 minutes. Allow at least 30 minutes to reach temperature - e.g. an example schedule would be:
333C to 260C, hold for 20m, End. See information under the 'Product Downloads' tab.
The mixing ratio is 4-5 parts water to 1 part dry powder so if you are using 1litre of water you will need 200-250g of primer.
We recommend using our Boron Nitride Spray with stainless steel moulds for an easy release
Once the primer has been fired on your kiln shelf it should appear as a light pink colour
Yes you can use kiln wash on the surface of ceramic slumping moulds. If you are using plaster moulds, it is not necessary to use kiln wash
