The Smarter Way to Make Chalk
Most chalk starts in a mine.
REAL Chalk starts in seawater.
Magnesium is recovered from desalination brine, refined into ultra-pure MgCO₃, and finished for climbing performance—not industrial use.
Better absorption
Finer coverage
Less chalk per session

Most companies treat chalk like a commodity. We don’t.
Trango® REAL™ Chalk starts with pharmaceutical-grade magnesium recovered from seawater desalination—not mined magnesite pulled out of the ground and crushed.
That difference matters.
How Desalination Works
Seawater is pulled in offshore and filtered to remove sand and organic material. From there, it’s pushed through reverse-osmosis membranes that separate clean freshwater from salts and minerals.
The freshwater goes one way. The minerals go another.
That mineral stream—called brine—is rich in magnesium. Instead of treating it as waste, the magnesium is recovered and refined into high-purity magnesium carbonate.
Same desalination system; two useful outputs. Cleaner water and better chalk—without digging more out of the ground.
