Painting Bag 38 Piece Set

Dry crayons are also a kind of pencil, the thin stick inside the pencil that leaves a mark when rubbed on the paper is not lead as it is thought.

This rod is made of lead-like graphite. Dried and pulverized graphite is mixed with clay and water. The hardness of the pencil depends on the clay content in it.

It gets harder when the clay ratio is increased, and it softens when the graphite ratio is increased. The hardness or softness of pencils is indicated by letters and numbers. The mixture of graphite and clay, which is brought to the consistency of dough, is passed through the press and thinned like a rope, cut into equal lengths and then fired. While these processes are being carried out, the wooden outer part of the pen is prepared. Shaped into two halves of cedar or pine wood, the wood is hollowed out to accommodate the graphite rods.

Baked sticks are placed in this cavity. The two halves are brought together and glued together with glue. Crayons are made from kaolin mixed with beeswax glue and coloring agents. Sometimes this mixture is wrapped in paper before it hardens. As the spirally coiled paper strip unwinds, the tip of the pen also unwinds. Copy pens are also made from a mixture of aniline paint, graphite and kaolin.
