Notes
*At 100% Ravenscrag Slip produces a silky gloss almost transparent glaze at cone 10R. It has a much more natural quality than a transparent made from refined mineral powders.
A glossy white can be produced with an addition of Zircopax (like GR10-CW).

Notes
*A stunning matte translucent base glaze that is achieved by a simple 10% addition of talc (it supplies the MgO to create the "dolomite matte" effect).
A mix of 1000 powder, 1000 water = ~1.42 specific gravity, producing a good slurry for use as a dipping glaze in our studio.

Code # GR10-CW |
| Materials | Amt |
|---|---|
| Ravenscrag Slip | 35.000 |
| Ravenscrag Slip 1000F Roast | 52.000 |
| Silverline 303 Talc | 10.000 |
| Additions | |
|---|---|
| Zircopax | 6.000 |
Total:103.00
Notes
*The Zircopax addition increases the gloss and the opacity of the GR10-C base recipe.
In our lab 1000 powder and 920 water produce a good consistency for use as a dipping glaze.
The 52:35 ratio is being used (rather than the normal 45:45) to minimize cracking during drying and compensate for the zero LOI of the roast material.
