itc on silicon carbide, a different question

Lela,

You might suggest that this be one of the regular maintenance chores that
every member has to perform. It should not fall on you alone to clean off
shared shelves. It also sounds like the kiln wash is way too thick!

I have seen this type of thing occurring in various studios/guilds. I have a
few questions for you.... Do members also leave the wheels/tools/work
surfaces a mess? Are you having to clean up before you even sit down to
work? Are you losing pieces through no fault of your own? Are you getting
upset?

If the answer to my questions is yes and you are getting nowhere trying to
implement an agreed remedy then my best suggestion is to start working on
establishing your own studio. I did and it was WONDERFUL!

Hello,
I got a used gas kiln recently that came with shelves already coated =
with flaking old kiln wash. I didn't want to grind them down since I =
was so excited to fire the new kiln. So I put my kiln wash over the old =
stuff and fire away. Now that the full excitement and adjustment to gas =
firing is settled, I am taking a couple of my shelves at a time and =
using a side grinder with a masonry disc on it to grind all the kiln =
wash off the shelves. USE A GOOD DUST MASK AND GOGGLES!!!!! It is lots =
of work, but it will be like starting over. I may have lost a little bit =
of shelf surface, but at least I don't have to worry about the old wash =
flying around the kiln.

I use my Dremel with a sturdy grinding bit (bought at the flea =
market cheaply) to clean kiln wash & fired- in glaze from my kiln =
shelves. =20
Do it outside & stay up-wind! It makes lots of dust.

There are several different options. One is to fire everything on clay
cookies. another is to use an rotary grinder. The type they use in
auto body shops. We use this at the art center where I teach. About
every three months or so I grind off the kiln wash and glaze drips and
flip the shelves.

In our guild situation, the shelves  are often a mess. Some members don`t scrape before applying yet another coat of thick wash. An independant potter told me that a quick sandblast from our local  monument carvers did the job for him once. In his beginning years he had mistakenly applied glaze to the shelves rather than the kiln wash. Terrible mess.. but the sandblasting made the shelves like new. I approached the guild about this, but they didn`t go for it because blasting would also take off a thin layer of the shelf. I knew that but figured it was worth it. These shelves are terrible, flake off all over. Sandblasting costs 65$ an hour. The guild did buy 6 new half shelves. I scrape them often, but unless I spend a long day at it, can`t get all the gunk off. Would really like to know what some of you think.   Happy New Year to you all.        Lela

Hi Lela, Could you possibly get them to agree to try just one as an
experiment? Then they could see for themselves if it is a good idea. Th=
e
monument person might do just one in the hopes of a large lot to follow.
Just a thought. Rikki Gill rikigil@cwnet.com
