Pink, Crimson, Red and Coral Mason Stains
Shop Pink, Crimson, Red and Coral Mason Stains from Mason Color Works for coloring glazes, slips, underglazes and clay bodies. Chrome-tin pinks and crimsons (#6000–#6006) are stable from cone 06 to cone 12 but need a high-calcium glaze with little or no zinc or magnesia, moderate boron, and an oxidizing firing. For bright reds and oranges, see our encapsulated stains.
Looking for a specific stain? Use the Mason Stain Finder to search all of our Mason stains by number, old K-number or name, and filter by color, zinc and calcium needs, body stains and cadmium-free colors.
Every Mason Stain is sold by the quarter pound and ships free. Quantity discounts apply automatically: order 4–19 of the same color (1 lb or more) and save 33%, or 20 or more (5 lb or more) and save 44%. All quantities of a color ship together in a single bag.

Reference notes (“See Ref.” column)
1. Can be used as a body stain in porcelain at high temperatures. All brown colors can be used as body stains, but the shade varies considerably with the clay body and firing temperature.
1a. Use only as a body stain.
2. Max. firing limit 2156°F (1180°C).
3. Max. firing limit 2300°F (1260°C).
4. Max. firing limit 1976°F (1080°C).
5. Do not use zinc in the glaze.
6. May be used with or without zinc.
7. Zinc is not necessary, but gives better results.
8. Best results with no zinc.
9. The glaze must contain 6.7–8.4% CaO (12–15% CaCO3).
Firing temperatures are only a rough guide: firing at 2200°F on a slow schedule may mature a glaze as much as 2300°F on a fast one, and the cycle, atmosphere and cooling rate all affect the color. Zinc oxide influences glaze color more than any other element; zinc already combined in a stain will not harm the color, but free zinc oxide in the glaze can destroy it. For calcium, adding the molecular equivalent of CaO as wollastonite often gives better uniformity – subtract the extra silica it adds, or the glaze surface will suffer. More help: Mason Stains FAQ.
