Hello I've twice boiled some water (tap water which is from a well) and forgot to turn off the stove. The water all dissipated but leaves this sandy colored substance at the bottom. Its quite visible and seems to be quite a lot of it. What could be causing this ? The pot is a kitcheaid relatively new pot.

 

Thanks

Have you thought of silt??

 

sandy colored

 

Bit vague.

Limescale coloured with some suspended microscopic particles, probably, to give the slightly browner colour.

Ordinary water is not free of ions. Most ionic substances are not volatile; when the water is boiled away, they stay behind.

Rock dissolves in water, rather better than most people expect.

If you remove the water, you are left with the rock.

If the sandy stuff reacts with vinegar to produce bubbles of gas, that would suggest that it's mainly limestone- but other rocks are also options.

Hello and thanks for the response. I've never seen what does silt look like. Maybe I'll take a snapshot and post the picture here. From the Google search I did it does seem to appear like a type of silt. Is drinking water with silt in it dangerous ?
