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.
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.
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!

I’m taking a ceramics/pottery class at my local community college and when it came time to start glazing my pieces I realized we didn’t have any purple hues at all - purple was really important to me in my work.I found this glaze and it was the purple of my dreams. It came out exactly how I wanted it! Some of my pieces were fired in the electric kiln and some of my pieces were fired in reduction and all of my pieces came out absolutely stunning. Don’t hesitate to order this glaze for your art!

It looks nice but, you have to build up the layers otherwise it will be more of a blue color. Looks pretty good with 7 layers. Easy to use and great value for the money. Good quality not glossy.
