Tobermorite is a calcium silicate hydrate mineral with chemical formula: Ca5Si6O16(OH)2·4H2O or Ca5Si6(O,OH)18·5H2O.

Tobermory is the capital of, and until 1973 the only burgh on, the Isle of Mull in the Scottish Inner Hebrides. It is located on the east coast of Mishnish, the most northerly part of the island, near the northern entrance of the Sound of Mull. The village was founded as a fishing port in 1788; its layout was based on the designs of Dumfriesshire engineer Thomas Telford. It has a current population of about 1,000. It is notable for appearing in the 2002–05 children's programme Balamory by the BBC.
