Nature's textures i - Halite
Posted by dobbino (Cape Town, South Africa) on 25 March 2009 in Plant & Nature.
Halite is the mineral form of sodium chloride, NaCl, commonly known as rock salt. The mineral is typically colourless to yellow, but may also be light blue, dark blue, or pink, depending on the amount and type of impurities it contains. The structure of the mineral is intriguing in that it consists of the most unusual shapes, which break down to form the normal salt crystal as we know it (you can see these at the bottom half of this sample).
A friend of ours at our flat complex has a collection of rocks and other natural substances, and this is the first of three photos taken of items from the collection. Each has a unique texture, but for me, this was the most fascinating.
All comments, and especially constructive criticism is truly appreciated. Thank you for taking the time.
