Chrysanthos Underglaze Pencils are lead-free and non toxic and are intended for use on bisque where it is desired to create a fine line or shade. They can also be used for identification or marking test pieces.
After application of Underglaze Pencil color to bisque, the color should be coated with a clear glaze before firing to the glazes maturing temperature. The first coat of glaze should be sponged on over the Underglaze Pencil 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 Pencil design.
Note that unlike regular pencils—care must be taken in sharpening Underglaze Pencils. Do not use a pencil sharpener. It is best to sharpen them with a knife or blade.
Chrysanthos Underglaze Pencils may be fired between cone 06 (999°C) and cone 10 (1,305°C) except for UP005 Brown which can be fire to a maximum of Cone 6 (1,222°C).
