What is Bluestone? Bluestone is a colloquial term for many different natural stones around the world. In NSW and Victoria, Bluestone usually refers to Basalt. In South Australia Bluestone refers to a local Slate. At Cinajus, all our Bluestone products are natural Basalt that is valued for its strength and durability.
Basalt and Bluestone is an extruded igneous natural stone. It is the most common volcanic rock on the planet and is formed when basaltic lava flows cool. Basalt and bluestone is similar in density and strength to Granite and some basalts have been mistakenly sold as granite. The colour of bluestone typically ranges from grey to charcoal.
Bluestone can sometimes have small holes or cavities called vesicles. These are formed during the extrusion process when magma rises to the surface and the pressure on it decreases. As this happens gases are able to come out of the solution creating larger bubbles that are caught in the lava as it cools. These vesicles can either be in occasional small patches like our sawn Balmoral Bluestone Sawn pavers or more consistently through the stone like our Balmoral Bluestone L-Ho cladding.
