Cone 10 Malcom Davis Carbon Trap Shino
The original recipe is as follows... (our studio version plays with shorting the recipe a bit on the soda ash.)
Malcom Davis Carbon Trap
Soda Ash 16.30 (10.30)
Nepheline Syenite 38.60
Kona F-4 Feldspar 9.30
EPK Kaolin 17.00
OM-4 Ball Clay 13.00
Multiply by 100 to make a 10,000 gram batch. This makes enough to top-off a 5 gallon bucket.
Mix the soda ash into a solution and add to the mix after the ingredients have been dry mixed and slaked.
This glaze is mostly seen on porcelain, but works with excellent effect on buff white clay bodies as well.
As with all glazes, I highly recommend learning to playing with this glaze by taking risks and figuring out why things work, and more importantly... why they don't.
