I. The Metaphysical Reading

How the stone has been held.

Copal is worked with as a resin of purification, burned in ceremony across Mesoamerica and worn as a warm-hearted stone that keeps company with the sun. Practitioners hold it as a reminder that not everything ancient has to be finished — some things are still becoming.

II. The Scientific Reading

What the lattice actually does.

Copal is a sub-fossil tree resin — an intermediate stage between fresh conifer or leguminous tree exudate and true amber, typically only thousands to a few million years old rather than tens of millions. It has not yet fully polymerised, which is why it softens under a hot needle, dissolves in ethanol and alcohol solvents, and retains a strong resinous scent that fully mineralised amber has lost.
