Product Information

Genuine celadons are fired in reduction, i.e. the atmosphere of the kiln is starved of oxygen. When a small amount iron is included in the glaze it can create an amazing range of greens, blues, and in-betweens. Potters have long sought to impersonate their delicate qualities in the modern electric kiln. In this tradition, Hot Clay have included within the Vitraglaze family a range of glazes which will add to our already bestselling opaque green celadon.

The set consists of 6 colours:

Opaque Celadon Green

Opaque Celadon Blue

Transparent Celadon Green

Transparent Celadon Blue

Transparent Celadon Yellow

Vibrant Jade

Great inspiration can be found here for the colours and forms of celadons.

This glaze is available until the 21st of April 2025.
Order before promotion ends to avoid disappointment.

We are looking for feedback, good, bad or indifferent. Please feel free to contact us at info@hot-clay.co.uk. Let us know which glazes you like/don't like, difficulties you encountered, ideas you have and of course show us what you have made.

Firing Range

1222°C to 1280°C (Cone 6 to Cone 9).

The sample shows two applications on Vitraclay White Throwing Clay, fired to 1240°C.

Working Notes

The opaque glazes work well on off white to buff clays, whilst the transparent glazes work better on the pure white clays. Use transparent colours thinly for greater effect.

These notes are continuously reviewed so please send us your feedback.

Health & Safety

Vitraglaze is lead free and non-toxic.

Good housekeeping is essential in any pottery studio to minimise inhalation of silica dust.

Always clean up with a damp sponge and if any dust is airborne, such as when mixing powder glazes, wear an FFP3/P3 mask and filter.

Preparing a powder glaze

Always wear a mask when mixing powdered glaze.

Dipping and pouring mixtures need to be tested on samples before being applied to final wares.

This method of application requires an understanding of the behaviour of liquid slurries on absorbent clay bodies, as results can vary for many reasons. Because of this, it is impossible for us to guarantee your wares will fire to the same colour advertised. Here is some useful further reading.

The glaze mix should have a single cream consistency. A useful tip is to use less water in the beginning as you can always add more. After mixing with water, use an 80 mesh sieve for stoneware and a 60 mesh sieve for earthenware.

For more about a dipping glaze, read our general advice.

Applying a brush on glaze

Remove glaze from the pot, stir and agitate the glaze in a larger container, make sure all the material is mixed thoroughly.

Whilst keeping the glaze moving, dip your brush and hold it sideways to keep the material evenly distributed.

Apply using confident dabs, move the liquid around and work quickly and smoothly.

2 to 3 applications could be needed so allow to dry between coverings.
