Introduction of crayons
Crayons are pens made by mixing pigments with wax. There are dozens of colors available for painting. Crayons have no permeability and are fixed on the screen by adhesion. It is an ideal tool for children to learn color painting. Some painters use it for sketching and color recording.
How are crayons made?
Crayons can be made by casting and extrusion methods. The general ratio is 40% C16～C18 fatty acid, 40% wax, 5% various pigments, and 15% various fillers. If the extrusion method is used, more fillers can be added.
The variety of wax depends on the surface of writing materials such as glass, metal, wood, fabric, or other artistic requirements. Adding ingredients that enable the pigment to disperse when exposed to water can make the lines permeate and diffuse when exposed to water. This writing material is a new variety of crayons.
The effect of crayons
The crayon drawing will have a soft and casual feeling. The effect drawn by different paper crayons will be different. For example, the crayon drawing on rough paper has a grainy color, but the color is very saturated.
Crayons are dry and have brighter colors. They work best on cardboard.
