AMACO Celadon C-11 Mixing Clear High Fire Transparent Gloss Glaze Pint, 16 oz. (473 mL), Cone 5-6 Liquid Ceramic Pottery Glaze for Bisque Review (2026)

What Mixing Clear is designed to do

C-11 sits within AMACO's Celadon line of cone 5-6 high fire transparent gloss glazes, and its specific role is as a mixing base rather than a finished color on its own. According to AMACO and its retailers, this glaze is 100 percent mixable and is used to soften the color intensity of other Celadon glazes, letting a potter dial down a strong color to a lighter tint by blending in varying amounts of the clear. That mixing role is the main reason to reach for C-11 specifically instead of a standard clear glaze, since a plain clear intended only for topcoat use is not necessarily formulated with the same blending behavior when combined with other glazes in the same line.

Firing range and finish

This glaze fires at cone 5 within the broader cone 5-6 range that defines AMACO's Celadon high fire line, giving it a gloss, transparent finish once fired that shows the clay body or any underglaze decoration beneath it. Firing a cone 5-6 glaze correctly depends on an accurate kiln and reliable cone placement, since underfiring can leave a glaze under-matured and prone to issues like pinholing, while overfiring can cause excess movement or crawling on some clay bodies. As with any glaze, running a test tile through your specific kiln's cone 5-6 schedule before committing to full pieces is worth the time, since kiln behavior varies even among kilns nominally firing the same cone.

Food safety and testing

AMACO markets its Celadon cone 5-6 glazes, including C-11, as AP non-toxic and dinnerware safe, and the line is generally described as free from lead, which supports use on functional ware like mugs and plates once fired correctly. That said, manufacturers and sources note that tableware producers should still test their own finished ware to confirm dinnerware status, since variations in firing temperature, glaze application thickness, and possible surface contamination can all affect whether a specific fired piece is genuinely food safe in practice. Treating the manufacturer's dinnerware-safe listing as a starting point rather than a guarantee for every fired outcome is the more careful approach for anyone selling or gifting functional ware.

Container size and practical coverage

This listing is for a pint, equal to 16 ounces or about 473 milliliters, which is a workable amount for a hobbyist or small studio mixing tinted batches from a handful of colored Celadon glazes rather than dipping large volumes of production ware. Because the primary use case is mixing rather than straight application as a standalone clear, a pint tends to go further than it would if used purely as a topcoat glaze on every piece, since it gets blended into smaller portions of colored glaze rather than applied at full strength across an entire batch of ware.

Verdict and who should buy it

This glaze suits a potter already using AMACO's Celadon cone 5-6 line who wants to soften or tint existing colors rather than someone looking for a simple, standalone clear topcoat glaze. Its mixing role is the main selling point, and it fits naturally into a mid fire studio that already fires in the cone 5-6 range with an accurate kiln. For someone who just wants one straightforward clear gloss glaze to dip finished bisque ware without any mixing or blending step, a dedicated clear glaze made for that single purpose may be the more direct, less involved choice.
