GR10-A Ravenscrag Cone 10R Base Glaze

Description

All by itself, Ravenscrag Slip fires a slightly silky transparent at cone 10R. You can use it like this, or add a little talc for very silky matte. Or add zircopax to opacify it.

H550 and glazed with Ravenscrag Bamboo GR10-J1 (outside) and GR10-C Ravenscrag Talc Matte (inside). By Tony Hansen.

Recipe

Left: G2571A magnesia matte glaze on H440 fired at cone 10R. Right: GR10-J is the same glaze (having the same chemistry) but made using Ravenscrag Slip to supply much of it.

The inside glaze is pure Ravenscrag Slip GR10-A and the outside glaze is a 50:50 mix of Ravenscrag and Alberta Slips (GR10-E). By Tony Hansen.

P580 with Ravenscrag GR10-A and G1947U liners. The Ravenscrag is not quite as glossy and it contains enough iron to darken the color of the underlying porcelain. Zircopax could be added to whiten it, however it is best to limit the use of GR10-A to ware that has compatible aesthetics.

This is GR10-C Ravenscrag Talc matte on H440 and H450. Fired at cone 10R. The recipe is just pure Ravenscrag with 10% talc added.
