MARKING CRAYONS

Two different types of marking crayons are commonly used:

On one hand, marking crayons that are composed and manufactured in the same way as colour pencil leads and impregnated with grease/wax. They are particularly suited for marking cardboard, paper, wood, metal as well as all rough surfaces.

On the other hand, wax marking crayons that are manufactured like grease leads (glass marking pencils). In these crayons the grease/wax mixture functions as the binding agent. They are preferably used for smooth surfaces like glass, plastic, leather etc. They are highly light-fast and heat-resistant (the colour white up to 1000° C). Their strokes are water-resistant.
