Underglaze Chalk – 6 Pack – 1


Our “Underglaze Chalks” can be used for decoration or just marking ware. As they are fired higher they tend to fade. To not smudge any work, glaze should be slightly sponged on the design before brushing or dipping.



Chrysanthos Underglaze Chalks are lead-free and non-toxic and are intended for use on bisque where it is desired to color or shade larger areas.


Decoration with Chrysanthos Underglaze Chalks are suitable for use on most types of clays for decoration.

Shades are created by first wetting and a brush and using it to smear a color that has been applied to bisque. Shades may also be created by using a wet or dry finger to smear color that has been applied to bisque.

Two or more colors can be smeared together to create other colors or shades using the same technique as for one color.

After application, excess dust should be brushed off gently and the decoration  should be coated with a clear glaze before firing and fired to the glaze maturing temperature. The first coat of glaze should be sponged on over the Underglaze Chalk design to prevent the design from coming off if a brush on glaze is used. If the glaze is to be sprayed on or dipped on, it is not necessary to sponge any glaze on over the Underglaze Chalk design.


Chrysanthos Underglaze Chalks may be fired between cone 06 (999oC) and cone 10 (1,305oC).


Chrysanthos Underglaze Chalks are lead free and are safe for children to use.

Care should be taken when brushing off excess chalk dust so as to not inhale the dust particles that are created during drawing.

Once coated with a suitable food safe glaze, the chalk decoration is food safe provided the glaze has been fired correctly.
