We are having a problem with our kiln wash flaking off the shelves. Does
anyone have a solution? Also, is there an easy way to remove the old kiln
wash?

Thanks,

Gayle:

Take your shelves to a car repair/paint shop and have them
sandblasted. Be sure to emphasize that the shelves need to
be supported on a few inches of sand or other form fitting
material (an uneven hard surface with encourage cracking).
Also, tell them you only want the surface removed - when
sandblasting it's way too easy to go deep). I have
5 1/2 round 22" shelves which I get done every 5 years or
so and last year cost me $25 for the bunch, cash.

It's the easiest method I've found.

Try Steve Branfman's kiln wash recipe:

2 parts EPK
2 parts flint
1 part Alumina Hudrate

I have used it for some time now; doesn't flake off; scraping shelves
with a rigid putty or spackling tool does the job; stubborn "drips"
require working with any type of flat chisel.

Good luck. Let me know how this works for you.

Lee's Kiln Wash from Axner's does not flake. I recommend it IF you have
hard shelves like Nitride bonded SiC shelves. I use a sharp coal chisel
and a wood chisel and hammer for the big glaze drips and then finish with a
6" Milwaulkee body grinder equipped with a wire cup brush to complete the
job. Wear eye protection and a respirator. ...Marshall

gad kiln wash on shelves?? use kiln wash for the kiln and use 100 mesh
calcined alumina mixed with wheat flour and water on the shelves...brush
onto the up side of the shelf. it falls straight off after the fire and can
be re used
or even easier, just sieve it on with a 60 mesh sieve (no water no flour)
again falls off after fire and can be reused the alumina gives the base of
the pots a nice gritty surface to slide over as they shrink and pots dont
stick to shelves at all...as for glaze drips, kiln wash won't protect your
shelves from them at all ...you have to grind the glaze off every
time...alumina doesnt protect your shelves in this way either and allround
i figure it is much cheaper in many ways than kiln wash... i have been
using this method on my shelves for over twenty years and some of them must
have been in constant use now for 12 or 14 years
