Does Crayola Chalk contain calcium carbonate
Crayola manufactures two types of chalk, extruded and molded. Extruded chalk, such as Crayola Anti-Dust White Chalk, primarily contains calcium carbonate. Molded chalk, such as Crayola Children’s Chalk (available in white or coloured), is a softer chalk, made of plaster of paris. This type of chalk is not dustless and not recommended for chalkboard use. Crayola Sidewalk Chalk is a molded chalk that is not intended for use on chalkboard surfaces. It does not include calcium carbonate. This product contains plaster of paris which has a gritty texture and may scratch your chalkboard. While Crayola Children’s Chalk is generally sold at toy, grocery and drug stores, Crayola Anti-Dust Chalk is normally found at school and educational supply stores. To locate a teacher/educational supply store near you, please check your local yellow pages under “school supplies.” If you need further assistance, please call (800) 272‑9652 weekdays between 9:00 AM and 4:00 PM Eastern Time and a representative will be happy to assist you.

In 1900, prior to the introduction of Crayola Crayons, we produced black marking crayons. Today these are known as Staonal brand Marking Crayons and are used in many industrial settings. These crayons were created with dry carbon black and different waxes. The first box of Crayola Crayons was produced in 1903 as an 8 count box. It sold for a nickel and contained the colours red, orange, yellow, green, blue, violet, brown and black. We provide extensive information about Crayola and our products on our sites. A history timeline can be found on the Crayola.com web site at our history.
In 1903, we introduced the first box of 8 Crayola Crayons and sold them for a nickel. Included were the same 8 colours that are found in an 8‑pack today: red yellow blue green orange brown violet (purple) black.
In 1958 the box of 64 CRAYOLA Crayons was introduced. It was the first package to include a built-in sharpener design. We continue to manufacture this package design today in the 64 and 96 count Crayola Crayon package.
In 1993 we conducted a poll to find out the most popular colours in America. Blue was voted the most popular CRAYOLA Crayon colour. Rounding the top ten were red, violet, green, carnation pink, black, turquoise blue, blue green, periwinkle and magenta. In 2000, we did another Crayola Colour Census, and blue again reigns as number one!
