The traditional alternative to writing on whiteboards: chalk on blackboards. Available in white and assorted colours for use on black boards and creative play and craft.
Chalk is made from Calcium Carbonate which occurs naturally in Limestone. The Limestone is quarried, crushed, ground to fine particles then mixed with water to form a slurry. This is then formed into long thin rolls or sticks, baked slowly in an oven, cooled, cut to size and boxed. Non-toxic and dustless.
