Penguin Pottery’s glazes offer a huge range of effects to choose from: vivid, bright, smooth, glossy, textured, satin, matte; opaque, semi-opaque, semi-translucent, translucent, flowing, non-flowing. Our low fire glazes are perfect for school projects, classrooms, studios, and potters who do not fire at high temperature. These low fire glazes are the potter’s choice when looking for a wide palette of colors, like celadon, lively reds, deep greens, bright blues. Our mid fire glazes offer similar ranges but also introduce interesting effects and tonality not available in low fire glazes. Our glazes are lead-free, non-toxic and food safe (when properly fired and tested). Make sure to shake the jar well before using, and do not allow it to freeze. Try them out and let us know what you think!

• [COLOR PROFILE] - Denim Gloss features a rich, deep blue base with lighter blue and white highlights that create a soft, frosted effect. The surface has a subtle sheen, enhancing the layered color variation. Color transitions are smooth, with a slightly speckled appearance throughout.
• [PENGUIN POTTERY GLAZES] - Conscientiously crafted in Vermont, USA, our lead-free, non-toxic, food-safe mid-fire glazes bring you rich colors and effects you won’t find in low-fire formulas.
• [INSTRUCTIONS] - Always fire in a calibrated pottery kiln - not a kitchen oven - at the proper cone to match your swatch. Over- or under-firing can damage your work or yield uneven results.
