  • [DRY GLAZE]: 5 Lbs of Penguin Pottery Mid Fire Glossy Opaque White glaze makes approximately 8 pints of liquid glaze (1 gallon) for brushing, or even more if dipping.
  • Pottery glaze must be fired in a pottery kiln at the correct temperature. Do not fired in a kitchen oven. Your ceramic kiln must be temperature calibrated to confirm it is firing at the target temperature / 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 and possibly the kiln. Under-firing will give you ugly results that will not look like the swatch image.
  • Our glazes made in the USA by expert potters. They are lead-free, non-toxic and food safe (when properly fired and tested). Our mid fire glazes offer similar color ranges to our low fire glazes, but also introduce interesting effects and tonality not available in low fire glazes when fired in a pottery kiln at cone 5 or cone 6. Sometimes glaze contents will settle. That's normal! Ceramic glazes need to be fully mixed to ensure smooth application. We recommend mixing for at least 1-2 minutes.
  • 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.
  • [LIFETIME WARRANTY] - All Penguin Pottery products are backed by our Lifetime Warranty. if you have any issues, we will give you a refund or replace your product - no questions asked! See warranty & support section for more information.

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.

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

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!
