oldlady Posted June 5, 2018 Author Report Share Posted June 5, 2018 as the original poster, i recognize my duty to all of you latecomers to let you know what happened. i washed those shelves in october of 2012. i have done NOTHING with them since except load pots and remove pots. this week i had a long armed neighbor remove the shelf that has been in the bottom since i got the kiln in 2003? or so. i am going to have to raise that shelf since it is getting a little hard to reach all the way down into the kiln to place flat pots and remove them. most of my work is under an inch high so reaching is a problem now. the point is that the bottom shelf was not washed with the recipe given above (by weight) and when i turned it over huge flakes fell off the underside. very old kilnwash. USE THE CALCINED EPK AND A ROLLER. and glazes that do not run. if you glop stuff on thicker than the pot, guess what happens? Link to comment Share on other sites More sharing options...
Marcia Selsor Posted June 6, 2018 Report Share Posted June 6, 2018 I use 50 silica, 50 kaolin I add 5% Alumina for good measure. What temperature and what atmosphere. I pit alumina Hydrate in my liquid wax for ^6 porcelain to avoid plucking. Marcia Link to comment Share on other sites More sharing options...
