ᐅ Sanitary fixtures made of mineral cast with innovative designs

Hello,

Mineral cast elements usually have more interesting design shapes and are often quite affordable; I find the issue of lower heat resistance less critical in the bathroom, but the risk of scratching is more concerning.

Now the question:
Are there significant differences between manufacturers in this regard, especially in terms of measures to prevent scratching, such as additional coatings?
For example, Duravit promotes Wondergliss, which is also supposed to make cleaning easier...

Thanks

Addendum:
Duravit, of course, promotes not only Wondergliss but especially Durasolid and similar products – other manufacturers likely offer comparable options...

So, how significant are the differences, or is mineral cast simply mineral cast with all its advantages and disadvantages, no matter who produces it or which coating is used?
