Stoneware — Brooklyn, New York

Each vessel carries the pressure of thumbprints and the silence of a twelve-hour firing cycle.

Iron-Rich Stoneware

Coarse, volcanic memory in every surface

The body I return to most. Fires to a dense, resonant grey-brown that shows every thumb mark. The grog gives it structural memory — you can feel where the clay wanted to move.

Origin

Catskill basin, NY

Grog

20% medium grog

Firing

Cone 10 (2381°F)

Glaze Chemistry

Click to fire.

These are real recipes from the studio archive. Each field shows the glaze before and after the twelve-hour cycle. Click any field to fire it.

Iron Tenmoku

Fe₂O₃ 8%, Silica 35%, Feldspar 40%

Fire →

Breaks amber at rims and edges where glaze thins. Pooling creates depth like dark water.

Unfired — ochre slip

Pale Celadon

Fe₂O₃ 1.5%, TiO₂ 0.5%, Silica 30%

Fire →

Fires to a translucent grey-green in reduction. Pools in carved lines like celadon on Song dynasty porcelain.

Unfired — pale green slip

Carbon Shino

Nepheline Syenite 80%, Spodumene 15%

Fire →

Crawls and blisters at full thickness. Carbon trapping creates smoke marks that record the flame path.

Unfired — thick white slip

Studio Violet

MnO₂ 4%, CoO 0.5%, Fe₂O₃ 2%

Fire →

My signature. Fires to the exact color of a kiln element at peak temperature. Gallery curators ask about it first.

Unfired — manganese purple

Full chemistry sheets, firing schedules, and temperature curves for all studio glazes are included in the Glaze Archive PDF. These are not approximations — they are the actual recipes in current studio rotation.

The Glaze
Archive

Forty-three glaze recipes in current studio rotation. Not approximations — the actual formulas, measured in grams per 100g dry weight, with firing schedules and temperature curves for each.

This is not a lead magnet. It is a document I use every week. Sharing it is how I find the people who understand that ceramics is chemistry as much as craft.

43 glaze recipes with full chemistry breakdowns
Firing schedules for cone 6, 10, and 04
Temperature-to-color transformation charts
Notes on reduction vs. oxidation atmospheres
Glaze layering combinations and results
