Mayco Ceramic glaze CG-1012 Haystack

Mayco Jungle Gems Haystack is a crystal glaze with a matte pale-yellow base and tan and orange crystals, with a glossier finish at higher temperatures.

At low fire, CG-1012 Haystack develops a matte pale-yellow base with tan and orange crystals. At higher firing, the base glaze becomes glossy, retaining its colour at the lower end of the high-fire range but fading at the upper end, while the crystals fade and melt. Greater flow and surface issues may occur. Always test on your selected clay body and in your own kiln before starting a batch or a project you plan to repeat.

Mayco Jungle Gems Crystal Glazes

Mayco Jungle Gems Crystal Glazes are designed primarily for low-fire use, where their characteristic base colours and crystal effects develop. They contain pieces of glass frit - the crystals, which melt, spread and bloom during firing to create irregular bursts of colour and pattern. Many colours can also be fired at higher temperatures, but the result varies by colour: the glaze may move and flow more, crystals can soften, fade or lose definition, and the base may become glossier, more transparent, lighter, darker or shift in colour. Check the individual colour's higher-firing information and make a test piece on your selected clay body in your own kiln before starting a batch or a project you plan to repeat. For fuller coverage and a more pronounced effect at low fire, apply 2-3 even coats to bisque and stir the glaze as you work, since the crystals settle to the bottom of the jar. On the final coat, check the placement of the crystals carefully, particularly near edges and on vertical surfaces.
