Random Sand Fact
Sand grains in ancient pottery from Grenada reveal journeys between Caribbean islands.
On Carriacou, researchers cut thin slices from prehistoric pottery and studied the sand grains under a microscope. The minerals and shape of the grains work like a geological signature.
When that signature was compared with the island’s own sand, some samples didn’t match at all.
The sand in one pot was rich in quartz and resembled sand from Barbados. In another, the minerals pointed to Puerto Rico. Sand, clay or finished vessels may have travelled between the islands hundreds, perhaps more than a thousand, years ago.
