Box of 100 White Chalk. For use on blackboards and creative play. Non-toxic and dustless. 100 pieces.
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.
‘Old fashioned’ perhaps, but Chalk is still an environmentally preferable option for writing on boards.
