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. Read more How to Get Great Results with Our Glazes Mix Well Before Using Sometimes glaze contents will settle. That's normal! Just like house paints, ceramic glazes need to be fully mixed to ensure smooth consistency. We recommend mixing well for at least 1-2 minutes. Choose How to Apply You can apply glazes either by (a) dipping your bisqued piece into the glaze or (b) brushing it on. Our glazes are ready to apply with a brush. If you're looking to dip, we recommend applying a dispersing agent like Darvan . Remove Dust from Bisque Removing all dust from your bisque-fired piece is critical to ensure a good outcome. Clean moist sponges are best. Make sure your piece is completely dry before glazing! Fire Glaze to Correct Cone Ceramic glazes are classified according to a temperature range ("cone") in three general groups: "low-fire," "mid-fire," and "high-fire." Over-firing will damage the piece/possibly the kiln, and under-firing will just give you ugly results. Read more A Note on the Art of Glazing Ceramics One of the fascinating aspects of ceramics is the slight variations we can achieve by using different clay bodies, glaze types and firing methods. It's like vintage film photography - you don't know what it'll look like until you get it out of the kiln! Glazes will react differently (and look different) depending on several factors, including: The temperature at which they're fired: even small changes in temperature can lead to different outcomes. The clay body on which the glaze is applied: the same glaze will look different if applied to a darker vs. lighter clay. The speed at which your kiln reaches the target temperature. How much oxygen is in the kiln's atmosphere while firing. That is why ceramics is an art! We recommend you experiment with different approaches and, most importantly, embrace the uncertainty. You will have a lot of fun seeing different results! Read more About Penguin Pottery Employee Owned and US-Based : our company was founded by and run by potters.
