Dixon Phano Peel-Off China Markers Brown High Heat 95 00095, Box of 12. Dixon Phano Brown High Heat china markers work the same as regular china markers, except they have a High Heat property so they won't burn off at high firing temperatures. Can be used in place of an underglaze pencil on ceramics and bisque ware. Dixon China Markers make beautiful bold strokes on almost any porous or non-porous surface including glass, plastic, film, paper, metal, and rubber. Marks wipe away clean from porous surfaces. No need for a sharpener. Pencils are paper wrapped with a tear string for easy sharpening.
