  • Pinnell Green Black Cone 6 glaze recipe
Categories: Glaze > Green
Firing Temperature: Δ6
Surface Type: Matte – Semi

Source/Alternate names: Clay Times

Firing Notes: cool maximum rate to 1472F (800C) hold 1 hour

Notes: Alisa Clausen: used Johnson Matthey J frit instead of 3134, local kaolin instead of Grolleg. Applied thick. A semi mat with movement in the surface. The glaze looks similar to the original Weathered Bronze where thinnest, but with a better melt and therefore slightly more gloss. However, where thickest, this is the brightest of greens of all of the Pinnell new formulations of Weathered Bronze. It is a strong aqua to grass green, with movement in the surface, showing some minute whitish streaking. It is black and green where thinnest. John Hesselberth has tested this glaze for copper leaching and recommends this glaze for decorative use only.

3% copper + 5 % Ti = more green
5% copper + 5% Ti = more black
Variation on Pete Pinnell’s Weathered Bronze. Black crystals, breaks black over
edges and texture. A bit more matte. See Clay Times Mar/Apr. 2004 for article p.19.

It’s the process of trusting the kiln environment to take over for the artist and paint the pot with flames.

I’m planning a test fire on one or two pieces in our next cone 10 reduction gas kiln firing at the Bosque Arts Center in mid-September.  I will add a photo after the firing.

Chun glaze is an ancient and traditional Chinese glaze. It is not usually very blue.
Tradtionally blue in a Chun is caused by the reduction of rutile, which can be chancy.
Expect a creamy glaze that spreads into several visual layers. You might get hints of lavender as well as blue.

A Bluer Chun

Cone 9-10 (Frits Hommes variation)
Start with the basic Blue Chun recipe above. To the 10,200 g recipe, add 96 g cobalt carbonate.
Leave out the copper carbonate (but keep the rutile in). This yields a light blue Chun with consistent light blue color, while preserving some of the traditional Chun color variation

This usually comes out as a very attractive light yellow. It reacts with iron in the clay body, typically forming brown spots and streaks.
