Can anyone help me with colored slip? I'm wanting to use slips b/c my kiln
will not fire to cone 10 anymore and cone 06 glazes are too expensive for
my studio budget. Can someone help me with how to make different color
slips (recipes?) and where I can buy the raw material for them at? Any
other info would be great as well! Thank you!!

You can make you own ^06 slips, and all sorts of
glazes and engobes as well. There are many
recipes available. 'The Potter's Complete Book
of Clay and Glazes'by James Chappell is basically
a big recipe book with sections for every standard
temperature range. There are other books as well,
including books focused on all aspects of low-fire
work. There are also quite a few recipes in the
Clayart archives.

Materials can be purchased from retail ceramics
suppliers (located in most large cities), or by
mail-order. Pick up a copy of one of the major
ceramics magazines (Ceramics Monthly, Clay Times,
etc) and check the ads. Many companies now have
websites with online catalogs. Start by looking
for a company relatively close to where you live,
since shipping costs typically increase with
distance.

Another option (sort of a 'halfway homemade' choice)
would be to buy commercial dry glaze mixes - just
add water, and a little CMC or bentronite if it
suits you. Several companies make these, and though
the're more expensive than making your own, they
are much cheaper than those silly little jars.

I sympathize with your situation - I had to live
for a time in a house with inadequate power, and
my kiln could only achieve earthenware temperatures
with the available power, so I started working in
earthenware. Those little jars of commercial glaze
are a sure way to go broke, especially since making
you own is not too difficult. Slips and engobes are
a good way to start, since they are not fussy about
mixing or firing, and when used under a small range
of transparent colored glazes can give a huge range
of effects.

Good luck! -Snail
