This glaze is more silky (less matte) than the GR10-J glaze, it is much more beautiful visually and to the touch than a photo can convey. It works well all all clays, but especially buff and dark stonewares.

GR10-C Ravenscrag glaze on grey stoneware.
GR10-C Ravenscrag cone 10R silky matte glaze (90% Ravenscrag Slip, 10% talc) produces stunning surfaces and has excellent slurry and application properties.
Same body, same glaze. Left is cone 10 oxidation, right is cone 10 reduction. What a difference! This is a Ravenscrag Slip based glaze on a high-fire iron stoneware. In reduction, the iron oxide in the body and glaze darkens (especially the body) and melts much more. The behavior of the tin oxide opacifier is also much different (having very little opacifying effect in reduction).
Cone 6 Ravenscrag Silky Matte on Plainsman M340 (left) and M370 (right). The inside of the M370 mug is a transparent glossy. This recipe produces a silky ivory-coloured surface of very good quality. Go to Ravenscrag.com for more info.
Fired at cone 10R
B-Mix is a popular high-ball clay very plastic grey cone 10R stoneware in North America. The two mugs on the left have pure Ravenscrag Slip on the inside (the middle on the outside also), it fires almost transparent with a slightly silky surface. Pure Alberta Slip is employed on the outside of the left one and the inside of the right one. The outside of the right one is RavenTalc silky matte. In all cases the Ravenscrag and Alberta Slip are mixed half-and-half calcined and raw. B-Mix fires dark enough and with enough specks that a normal transparent glaze is not very interesting. But these Ravenscrag ones look much better (for liner glazes).
Left two mugs are pure Ravenscrag Slip, right is RavenTalc silky matte. The speckled mugs have 10% of Plainsman FiredRed (a concretion-containing red fireclay).
Fired at cone 10R. Clay is Plainsman H450.

A glaze that is not glossy. Of course, unmelted glazes will not be glossy, but to be a true matte a glaze must be melted and still not glossy. To be a functional matte it must also resist cultery marking, clean well and not leach into food and drink. Thus it is not easy to make a good matte glaze. I...
