The principle behind Graffito is exactly the same as carbon paper. Graffito sheets are embedded with a ceramic underglaze that will transfer to a bisque piece when drawn upon by using a pen or a pencil. This means that everything from photographic newspaper images to original drawings can be transferred to a piece. To set the transferred image, fire to Cone 013 to burn off the wax. All colours fire to Cone 8. They are sold in packs of 6 sheets that are 22 x 22cm in size.
