At the risk of sounding naive - and I know I should probably know the answer to
this but I don't. What do you do with glazes you've mixed and hate and never
want to use again? How do you dispose of them? I can't put them down the drain -
I don't want to dump them in the field. I've got buckets of glazes just sitting
here taking up space because I'm not sure what to do with them.

I think, a relatively safe way to get rid of waste glaze is to make a very
sound pot and fire the waste in the pot. Too be safe you may want to make
want to put it in a sagger, just in case it leaks. Fire it into a chunck of
glass for the landfill or a hole in your backyard. Break it up and use it
as filler under the next concrete construction you do. I also add small
amounts of scrape glaze to stoneware clay batches. So far this has not
caused any trouble, but definitely go easy here and cut back on feldspar in
the clay body to allow for the flux. We work primarily with high fire, so
we don't have low fire scap to get rid of.

Dust to dust, ashes to ashes; these things came from the earth; why not
return them to earth? OK, so the colouring matter can be toxic in local
concentrations and lead is toxic, why not fuse them and make paper weights
or door stops? Nuclear waste was disposed in the past by dispersal. That is
no longer politically correct so folks are looking at sealing them in glass
ingots and burying in underground vaults. You could pour some into tall
vases to lower the centre of gravity but one should avoid too great a depth
as cracking could result if the coefficient of expansion was greatly
different. If you mix several coloured glazes together you will likely end
up with a dark colour. A welder could make up some moulds of steel to hold
your glazes securely for melting.

Hi Mary,
Why not dump all of those glazes you don't like into one big bucket. Every
once in awhile dip a test tile or a pot you are not too fond of into
this slop. Eventually you may have a bucketfull of something that you really
like. Of course duplicating it would be next to impossible but what
the heck. At least you didn't throw it all out....
Cheers,
Rod Wuetherick...
(Where his slop still looks just like that "slop"... Still dunping in old glazes
though)

make a big bisque bowl, pour in the glaze and let it dry out, then fire and
dispose of in your garbage.

In our area the glazes are required to be disposed in the toxic waste
dump. The same dump as used when disposing paint and batteries etc.
I hope this helps you out.

Timothy,
My advice on what to do with scrap glaze is: use it! I am a compulsive glaze
tester, and a lot of the tests don't work very well. One out of 5 that
really is usable is a good return. All the ones that don't work go into a
bucket. I also glaze in such a way that I can use a 100g sample, so I put
all the good ones into my work. My technique of glazing also produces a lot
of scrap, also (scraping the edges of tiles and sponging the backs- it's much
easier and quicker than waxing). This also goes into the scrap bucket, along
with the scrapings from the sides of the spray booth.
This scrap glaze is always a glossy medium to dark green, in either oxidation
or reduction, and is remarkably consistent from batch to batch, unless I've
been having lots of bad luck with a lot of similar glaze tests.
Of course, you may not need this much dark green glaze. So I add colorants
to mine, usually to make a glaze darker than the scrap. Recently a Clayarter
asked for a glossy black glaze, and I posted a recipe for a glaze I used to
use, Larry's Black. What I use now insdtead is scrap with the same
proportions of colorants added- some iron, some manganese, a little cobalt,
and sometimes a little chrome. Looks pretty much the same. If you add about
10% zircopax, you can lighten the scrap, and then you can add other colorants
for a lighter version of blue, green, or brown. Rutile often produces a nice
brown. Or try adding titanium for more crystal development. I get a real
nice grey by adding scrap 50-50 by volume to an opaque white glaze, and a
really great Hunter Green mixing equal proportions scrap, an opaque white
glaze, and a really glossy clear, to which I add some chromeand some cobalt.
I've even gotten purple by adding just tin oxide to scrap. Proportions are
a bit irrelevant here, because who knows what's in the base glaze anyway?
Next time you make a 100g glaze test, see how deep it is in a cup, mark
that, and use that to measure out 100g of scrap. Don't worry that it's not
exact, it won't be quite the same next time, regardless.
At one time I kept 2 scrap buckets, one for iron glazes, and one for
everything else. The iron one kept getting darker and darker, but the other
produced a gorgeous robin's egg blue. (What can I say- I LIKE blue!)
So don't throw that stuff away- it's not good to throw it down the drain,
it's a hassle to fire it to a block, and you've already laid out good money
for it. You can also use it for a liner glaze in closed forms, no matter
what it looks like.
Happy Scrappy!

Rod,
In the classroom I call these reasonably functional hash glazes WONDER
GLAZE A, WONDER GLAZE B, etc. We wonder what's in them. The name helps
market them to curious students.

"scrap" glaze bucket. Glaze only to be used on insides of pots. We have
had some remarkable results (never to be duplicated again but always a
surprise, usually welcomed).

In our class we call the waste glazes we use as Kitchen Sink. It's my
favorite glaze and is usally an almost clear light green. I'm always
disappointed when we run out!

Mix them all together and you usually get a sort of blah generic glaze that
can be used inside bottles and other forms where the way the interior glaze
looks isn't too important (test first!). Ocassionally you'll end up with
something quite nice which can be frustrating since you'll never beable to
figure out how you made it.

Frankly, as a blanket statement I think this is very bad advice. Although
stonewre glazes will work as fluxes in a body, some ingredients will
cause various problems with the clay. Over floculation, defloculation,
scumming, excess cristobolite formation, colored specking, poor glaze
fit are just some of these problems.
Skin contact with other ingredients
should be minimized, some ingredients are very hazardous to breath.

Ours are "Mystery, Mystery Tenmoku, Mystery Starry-night, Mystery Satin
Dijon, and Mystery Black" They are some of our most popular glazes at times.
A handfull of granular rutile is a wonderful addition to waste glazes.

Hi Tim,
I have a five gallon bucket that I dump not only remains of glazes into but
also the residue left in my water container after the water is decanted.
After the bucket is full, I use my jiffy mixer, then my talisman sieve and
have a new glaze. Usually a green and usually one that layers nicely over
others. If you get an iron brown, maybe it can be layered also.
