I. The Metaphysical Reading
How the stone has been held.
Mordenite is worked with as a stone of clearing and gentle release, both energetic and physical. Its fine radiating sprays are read as symbols of exhalation — a stone that helps let go of what has been held in for too long.

II. The Scientific Reading
What the lattice actually does.
Mordenite is a sodium-rich zeolite mineral that forms fine acicular to fibrous crystals in the vesicles of basaltic and volcanic rocks. Its open microporous structure allows it to exchange cations and adsorb water, making it useful industrially as a molecular sieve.
