Photo-based color candidates, not guaranteed substitutes. Test on your clay body with your application and firing schedule. Finish, opacity, movement, and dinnerware suitability may differ.
How matching works & catalog coverage

Colors are estimated from the middle of each manufacturer’s fired swatch photo and compared in CIELAB color space using ΔE76. Lower values mean closer estimated color. Candidates above ΔE 25 are omitted. This threshold is a broad discovery filter, not proof of a close fired match. There is no manufacturer or studio validation of these suggestions.

This catalog covers online listings from Mayco, AMACO, Spectrum, Coyote, Laguna, BOTZ, Clayscapes, Penguin Pottery, Speedball, and Mid-South Ceramic Supply (Opulence). Coverage varies by manufacturer and product line; it is not a claim that every current glaze is included. The Glaze category excludes engobes, sets, and standalone additives. The separate Underglaze category covers AMACO Velvet and Liquid Underglaze, Mayco Fundamentals, Kiwi Underglazes, and Colors for Earth Color Strokes and Color Concentrates. It excludes sets, tools, sprays, and additives.

AMACO Pearlescent was refreshed on October 12, 2026; the remaining catalog retains its prior snapshot. Supported firing cones and photographed firing conditions are different fields. A cone-6 swatch may appear different at cone 5. BOTZ Stoneware entries use Celsius ranges and require heatwork verification. PRO has a broad manufacturer cone range that includes cones 5/6, but its displayed swatch condition needs review. All BOTZ entries are excluded from color ranking in this release. Disable the BOTZ checkbox to omit temperature-based Stoneware entries.

Opulence product identities are sourced through a distributor listed by Mid-South because the manufacturer's website blocks automated access. Manufacturer photographs were unavailable for those entries, so placeholders are shown and color matching is disabled.

Finish is marked unknown unless supported by the series or product name. The finish filter excludes unknowns. No food-use suitability is inferred.

Underglaze comparisons stay within that category and use the selected bare or clear-coated condition. AMACO cone-5 charts and Mayco cone-6 chips are sampled from documented regions; photographed cones may differ from the selected firing cone. Clear glaze formulas and clay bodies may differ. Kiwi and Colors for Earth photographs are shown for browsing but remain unranked until an exact cone-5/6 sample is verified. Unknown chart layouts and missing samples are also unranked.
