Question: Is Drawing Charcoal Toxic?
Answer: Generally, no. Charcoal is made from willow or vine. The natural stick form is the purest. Most compressed charcoals use natural gums as binders. If you want to be completely certain, choose a brand that are labeled 'non toxic', and carry a certification such as the 'AP' seal of the Art and Creative Materials Institute, Inc.
Charcoal does create a lot of dust. Don't blow the dust off by mouth, as this can cause you to inhale the fine particles, which may cause lung irritation. A sharp tap of the drawing board will encourage particles to drop from the page, or flicked away using a very soft brush. Use a wet cloth or mop to clean surfaces. People who are sensitive to particle irritation or who frequently use charcoal in large amounts would be well advised to use a dust respirator (dust mask).
Note that carbone pencils and some charcoal-like products are actually made with waste carbon from burning oil, and/or may have oily and possibly toxic solvents and binders added. Ask your retailer for the MSDS (materials safety data sheet) for your specific product.
