The concept behind the new Flashed Mg2+ Sea Water Chalk was to go further. Solar seawater magnesium is a by-product of the salt industry requiring the flooding of coastal ponds with saltwater.

The process uses minimal space where ocean water is pumped into baths and the magnesium is precipitated out over the course of 20days. The process is slow and specialized producing only what we need. The final result is the highest puity chalk using XRD testing, with minimal environmental impact and maximum friction.

Flashed Mg2+ Sea Water Chalk Features: 

• Greater than 90% purity when XRD tested
• Nothing Added.
• NEW 100% Pre-cycled and recyclable paper packaging. Zero plastic.
