Mineral cast sink experiences?

Good evening dear forum community,

we are faced with the choice of the washbasin, especially the material. Currently, the choice is leaning towards a double washbasin made of [Mineralguss] from the company Inda.

I am curious about the experiences with the material [Mineralguss] in terms of care, scratches, etc. And whether glossy or matte is better?

The manufacturer does not matter, I am purely interested in the experience with [Mineralguss]. Should we go for it or rather leave it.

Many thanks!

I have no good experiences with it. We had one in the bathroom and one in the kitchen. The one in the kitchen is light gray and always looks dirty. We replaced the white basin in the bathroom last year at our own expense (rented apartment) because the children's foam bath caused stains that could no longer be removed. However, we also have extremely hard water, so limescale removers are not helpful either.

We have a white basin in the kitchen. It is true that discolorations can form there. However, they disappear again after some time and normal care. Otherwise, I simply left a mixture of descaler in there for about an hour. That pulls everything out. Of course, I have no idea what happens if you use that on other colors.

Otherwise, the whole thing is very robust. I also had concerns about what would happen after some time if you scrub pans and so on in there. But so far (after 6 years) everything is great.
