Colored pencil lead12/9/2023 ![]() Think of this as a pencil sandwich, with each slat acting like a piece of bread and the colored leads acting like the filling. Then a layer of glue is applied and a second grooved slat is placed on top of the slat holding the lead. To assemble the pencils, half of the grooved slats are fed into a machine which carefully lays a colored pencil lead into each groove. Since the leads are still quite moist, they must be dried in large ovens before they become hard enough to insert into the slats. As the long rope of wet colored lead comes out, an automatic slicer cuts it into equal lengths approximately as long as a colored pencil. The tube has a diameter equal to that of a colored pencil lead. These shapes are called cartridges.Įach cartridge, while still damp and pliable, is inserted into another machine called an extrusion press, where it is forced through a small tube. Finally, these sheets are machine-pressed into large, long solid cylinder shapes. When the mixing is complete, the contents of the mixer are rolled into flat sheets. First, the extenders, binders, pigments and water are placed in a large mixer which gently kneads them together into a uniform doughy substance. To make a colored pencil lead, you need four raw materials: extenders which make up the body of the lead, a binder to hold the ingredients together, pigment which gives each type of colored pencil its unique color and water to help uniformly mix all the ingredients. This seal assures consumers the product meets specific quality standards and contains no known toxic substances in sufficient quantities to be injurious to the human body, even if ingested. Crayola Colored Pencils have been certified nontoxic by the Art and Creative Material Institute (ACMI) and bear the Approved Product (AP) seal. In this case, lead is used as a generic term to describe the colored core of the pencils. These grooved slats are now ready to accept a colored pencil lead. Here they are fed into another milling machine which cuts small semicircular grooves at regular intervals down the length of each slat. The slats are then transported to the pencil making plant. The slats are the building blocks for the production of colored pencils. These slats are about as long as a colored pencil and about three inches wide. Next, the lumber goes through a series of milling machines which cuts the lumber into rectangular slats. Once dry, the lumber is fed into a bark stripping machine which removes all of the bark from each piece of lumber. ![]() Then, a new crop of seedlings is planted to replace those which have been harvested.Īt the sawmill, lumber arriving by the truckload, is stacked in large piles and allowed to dry. After a number of years, the trees are harvested, cut into even lengths, stacked onto trucks and shipped to the sawmill. Seedling crops grow into trees which are eventually used to make wood casings for the pencils. Seedlings, which are young trees, are planted in fields much like a farmer plants a crop. ![]() The process of making Crayola Colored Pencils begins in the forest. No tropical rain forest wood is used in making Crayola Colored Pencils. Reforested wood is wood taken from special tree farms grown specifically for gathering wood and are not part of the tropical rain forest. Crayola Colored Pencils are manufactured in Brazil and Costa Rica due to their high-volume manufacturing capabilities.Ĭrayola Colored Pencils are made from reforested wood. Today, Crayola markets a variety of color selections in packages of 8, 12, 24, 36, 50 and our largest selection, the 64 count package. In 1988, Crayola introduced colored pencils in their product line to fulfill consumer requests. ![]()
