Put under the microscope

Hello and greetings!

It is also important to keep up to date and well informed in the life of a mouse. And since I’m a modern Berti, I sometimes look at what’s being written about millstones on the Internet.

Either some mill sellers or bloggers don’t know what garbage they are writing, or they are deliberately fibbing? Because the things you read there made my magnifying glass fall out of my hand! “Natural stone mix”, for example. Is that like the egg-laying wool-milk pig?

Natural stone mixture! What is that supposed to be? Are you referring to the synthetically produced corundum-ceramic grinding stones? I have to protest!

This is because they have never seen naturally grown corundum (as mined in Crete, for example) in their entire short stone life. I write short stone life because they are not formed over centuries or even millennia in the mountains. Corundum ceramic grinding stones are fired in the oven like porcelain.
Naturally grown corundum does exist, but it is not used to make artificial grinding stones. That will not be done!

So what is this corundum-ceramic grinding stone now? Is this a mixture of nature and art?

No! This mixture does not exist and no matter how you try to call the artificial stone natural – the corundum-ceramic grinding stones are and remain artificially produced stones whose main component is aluminum oxide.

No question: the corundum ceramic stones grind well, for a long time and also very finely – but that doesn’t make them natural stones ! And no natural stone mixtures either! That has to be said, of course!
Greetings – your Berti, who is already looking forward to spring!
