The most ancient Mayan way of milling cacao nibs into a paste.
A beautiful piece of art.
Heavy natural granite stone mill.
Two horizontal natural granite stones: Runner stone (top stone) turns on the Bedstone (bottom stone).
Each of the stones is carved with harp-shaped furrows (groves), that are designed to continuously break the grain and press it slowly, the heat friction will transform the nibs into a fine cacao paste while also pushing outwards the processed cacao.
The processed cacao can then be put back into mill for further milling.
This ancient way of milling will require milling the grains several times until the desired result is reached.
