Typical fired chemistry
Median oxide analysis (weight %) across the recipes that report one, with the interquartile range. Silica and alumina set the melt; the fluxes and colorants make the family.

| SiO2 | 53.83% | 49.51–56.87% |
| Al2O3 | 10.17% | 9.33–12.52% |
| B2O3 | 3.29% | 2.76–3.62% |
| Na2O | 1.72% | 0.93–3% |

Questions
- What is a Oribe glaze?
- In 37 published recipes, Oribe glazes are mostly fired to cone 10 and cone 6 in oxidation and reduction, with a Glossy, transparent result. The defining materials are Whiting, Silica, Copper carbonate, Bentonite, Custer feldspar.
- What cone is Oribe fired to?
- The most common cones in published recipes are cone 10 and cone 6; the full distribution is on this page. Atmosphere matters as much as cone for this family: oxidation and reduction.
- What is the typical chemistry of a Oribe glaze?
- Median fired analysis: SiO2 53.83%, Al2O3 10.17%, B2O3 3.29%, Na2O 1.72%, K2O 2.94%, CaO 11.39%. Treat these as the centre of a range, not a target — the same family spans different fluxes and cones.
Sources. Every figure is a statistic computed by Claybench over 10,859 glaze recipes compiled from publicly shared community recipe collections (snapshot 2026-02-27); no recipe is reproduced. Colour-chemistry notes are paraphrased from Linda Arbuckle's Ceramic Materials handout.
Colorant and flux notes touch on materials with handling hazards (barium, cobalt, chrome, manganese, lead in historic recipes). Read each material's page and its supplier SDS before mixing; test any food surface.
