I work in a university that has fifty pounds of Burnt Umber in the glaze
room. The last studio I was in also had a large supply of this material,
but I can't recall ever seeing a recipe that used it. Does anyone know a
good recipe for glaze, slip, or other that contains Burnt Umber?

Not exactly a glaze recipe, but I've used it as a stain. Also good for staining
are burnt sienna, red iron oxide, yellow ochre...
Mix the Umber with water until fluid, brush full strength into the bisgued clay
surface. Alow to dry. With a damp sponge, wipe the stain off the surface. A
residue will remain in the cracks and deep texture of the surface (doesn't work
well on a perfectly smooth surface). Fire in your next glaze kiln. The results
are very dry and raw, and not healthy for food surfaces. But on the other hand,
the surface maintains a raw clay look. Excellent for emphasizing, texture,
carving, stamped impressions, etc.
***General warning when using raw oxides. Wear a mask when mixing dry
ingrediants. Wear gloves if you are putting your hands into the mix.
