We wouldn’t recommend mixing the colors themselves, but feel free to work with different ranges on the same piece! Just make sure you stick to the same firing temperatures across the ranges.

Also be aware that some glazes can run during the firing process! So test, test, test.

It sure is! If you fire it correctly and don’t see any crazing, pinholing or any other unwanted effects. 

If the entire piece isn’t covered with the range, give it a quick dip in clear glaze.

Crazing can happen for a number of reasons, BUT the number one reason is there is mismatched thermal expansion of the bisque and glaze.

Crazing can happen immediately or over time (the worst!). Other reasons are the glaze is applied too thick or under firing the piece.

Delayed crazing happens when moisture is absorbed by the body causing it to expand. 

Say goodbye to that piece, BUT read on to understand why this happens.

Pin holing basically is due to the expulsion of gases from the body or glaze due to:

• Under or over firing.
• Under firing bisque.
• Dusk specs on the bisque that stop the glaze from adhering to it.
• Application too thick.
• Firing the glaze too quickly.
• Too much recycled clay mixed with fresh clay.

We can’t emphasis enough the patience you need when applying a glaze.

• Wait for each coat to dry completely!
• Use the cross-hatch method when applying your layers. So, apply in one direction, and then the other. 
• Don’t assume more is better. Keep the layers thin and build them up. 

Could be a number of reasons, however, our psychic abilities are telling us it’s either underfired, the glaze is too thick, or your clay isn’t the right fit for the glaze.

Please store these in a cool, dark place with the lid tightly sealed. If you find it has dried out over time, you can add some Brushing Medium to help the glaze flow again and it will be good as new! Just give it a good shake before using it again.
