Can melted crayons be used as pigments?

Crayon is a pen made of pigment mixed with wax, which can have dozens of colors and is used for painting. Crayons are impermeable and are fixed on the screen by adhesion. It is not suitable to use too smooth paper or cardboard, and it is impossible to obtain composite colors through repeated superposition of colors. It is an ideal tool for children to learn color painting, and some painters use it to sketch and record colors.

Crayons can be made by casting and extrusion. The general proportion is 40% C 16 ~ C 18 fatty acid, 40% wax, 5% various pigments and 15% various fillers. If extrusion is used, more filler can be added. The type of wax depends on the surface of the writing object, such as glass, metal, wood and fabric or other artistic requirements. Adding water-dispersible pigment components to the manufacturing materials can make the lines permeate and diffuse in water. This writing material is a new kind of crayon. Preparation method of smooth crayon material

13 The researchers of Sakura Pigment Company developed an ingredient for producing smooth crayons, which consists of solvent, solvent-soluble polymer, glass pigment and gelling agent. For example, 20 parts of DenkaButyral2000L (polyvinyl butyral) is dissolved in ethylene glycol monobutyl ether, and then 4 parts of NikanolHP 120 (xylene polymer) and 7 parts of Hilac11(ch2o/cyclohexanone * * polymer) are added.
