Dustless chalk is designed to produce less dust when writing on a chalkboard compared to normal chalk. It is typically made with a different composition that reduces the amount of particles released. This can be beneficial for individuals who are sensitive to dust or for keeping writing surfaces cleaner.

What are the differences between living on chalk and clay?

Living on chalk typically results in alkaline soils, which can limit the types of plants that can thrive there. Chalk is also more porous and well-draining, which can lead to faster water runoff. On the other hand, living on clay can result in compacted and waterlogged soil, which may require more effort to improve drainage and aeration for plants to grow successfully. Clay soil tends to be more fertile than chalk, but it can also be more challenging to work with due to its heavy and sticky nature.
