Andesite is a volcanic rock, formed from lava cooling rapidly at the surface, which gives it fine crystal grains and a notably dense structure. The Andesite Natural Stone Basin is hand cut from it, with a polished bowl and lip set against a rough natural exterior, so you get a smooth surface where it matters and genuine texture everywhere else. Because each one is cut individually, the width falls between 45 and 50cm and the depth between 35 and 40cm, with variation in colour and shape too. There is no overflow, so any standard 32mm plug and waste or pop up waste without overflow will fit.
Please note: As each hand-cut basin is individual and unique as a one-off piece, no two basins are the same. There will be a slight colour, shape and size variation.
The name andesite is adopted from the Andes Mountains. It's because many andesite stones were found near the Andres Mountains. Andesite is a volcanic rock that forms above the ground surface. Andesite is composed of minerals with refined crystal grains. Andesite stones are formed from magma with temperatures between 900-1100 degrees Celsius. The formation of these mineral grains occurs due to the rapid formation of andesite rock from the lava flowing on the earths surface.
Another characteristic of andesite stone is it has fairly dense pores and structure. Environmental and weather conditions can produce dark brown andesite stones. Andesite stone is generally used in the construction of roads, bridges and runways.
