Carborundum

Band of sketchers prompt today hard. Carborundum is a man made creation, it’s exotic, iridescent, rainbow covered spikes are like something from a gothic fairy tale. Carborundum is thought to be a master healer that shines light in all areas of your life and connects to all chakras, purifies mind, body and spirit.’, a crystallography site…(Carborundum, second hardest thing to diamond on the Mo scale)

Water

I’ve just been reading a Facebook post discussing whether spring water is better than tap water, on the premise that tap water had more minerals in it.

I know that in Britain the water quality is regulated and that government checks that quality regularly.

Water from springs perculates through rocks with minerals in them. Over thousands or millions of years they pick up the minerals as they are dissolved by the water (rainwater will also contain dust particles from the air, and organic matter from the ground before it gets into the rocks). Then it depends on the geology. That’s why we have hard water and soft water. In some springs the water can be hot. Some were used by the Victorians¬† as purgatives as they contained high levels of things like sulphur. They were used as cures and remedies, the idea being that they cleansed the body.

Modern tap water contains a few additives like fluorine. But in measured amounts. My dad used to call it ‘corporation pop’. Not dangerous.
