Background Of The Birth Of Softened Board Crayons

Softened board crayons are mainly used for children's drawings, so they are also often called children's softened board crayons. The first "crayons" were originally made of a mixture of carbon black and oil. Later, carbon black was replaced by various powdered pigments, and other colors of "crayons" were produced. Strictly speaking, they are neither "crayons" nor oil sticks but marking tools.

Development Of Softened Board Crayons

It was later found that using wax instead of oil in the mixture was easier to process and the product was stronger and more durable.

At this time, a stationery company discovered that an industrial marker crayon used to mark crates, etc., was prevalent in schools, but it was made of carbon black and substances toxic to children. For this reason, they decided to develop inexpensive and safe colored softened board crayons for children.

The softened board crayons are made of colored pigments and solid paraffin wax.
