Ok, I resolved this one out.
If anybody would like to know a little bit of water and everything is ok.
Thanks you for letting us know-it really helps everyone when an solution is achieved and we all learn what it was. Even if our advice is wrong
Did the roughness go away as well??
Thanks for following thru.
Yep, all the "drapes" are gone. I took three 1 liter containers, added small amount of water to the first one, twice as much to the second and three times as much to the third. The second one was perfect.
Of course the roughness of the stoneware remained, but that is ok.
