Being cultured at IGaFA, a technichal school for aquaculture in Galicia, Spain.
A patch of healthy looking oysters attached to the rocks, left exposed when the tide was out.
Deep shell attaches, flat lid.
with black rock, lighter than you would expect (but does not float in fresh water). poor quality snowflake obsidian? with pumice inside to make light?? Looks more like wet coal (but absolutely clean, hard, no crumble at all).
