Sand from Polish beaches. Discovering the Baltic Sea part 3

It has been long known that Polish beaches are the most beautiful in the world!
Our sand is golden white, soft and does not stick to the skin.
It is as pure as glass – it has almost the same composition – 98% is transparent quartz, and 2% are other minerals and crushed rocks: pink garnet, orange tourmaline or black magnetite.
