rough inside, too much stone dust

The inside of the mortar is very coarse milled. The rough surface causes much fine gray stone dust forms. Presumably, that would be after a few weeks of use no longer a problem since then have worn all the bumps. As long as I do not want to wait, however.

I have a similar material and with almost the same design in Asia bought a mortar shop is inside sanded smooth. This has no visible abrasion and works just fine.

The Cilio mortar is more than 30 not cheap compared. Too bad that this is not directly supplied by the manufacturer inside sanded smooth.
