DFC Ceramics Marking Crayons are made for the

labeling or identification of ceramic goods in both

industrial and laboratory uses. These crayons

maintain their clarity up to 3000°F.

Ceramic crayons are used for labeling refractory

in the field (bricks, boilers, castables, IFB) and

laboratory testing. They are much easier and

convenient to use than chrome paint.
