[Clayart] cost of materials

I don't think people buying pints of glaze are trying to make a living, or
a profit, anyway. What they're far more interested in is bulletproof!

The local rec centers here charge between $20 and $40 for a class, often
taught by a 20 something with close to zero experience, but who is cheap,
cheap, cheap (the one center with $45 classes is taught by people who
really know what they're doing and they make their own glazes).
The rec centers use the ready made glazes because the people teaching the
class don't have any experience themselves.

It's the old story, pay peanuts and you get monkeys.

Not to mention that in most rec centers they don't teach you anything
besides making a pot and slapping a glaze on it. Nothing about firing,
nothing about troubleshooting bad glazes or bad firings, not even how to
mix up glazes.

WHen you look at the cost of classes, those expensive glazes are cheap. And
to be fair to Amaco and Coyote, some of them are really pretty nice and
they can take a lot of abuse (i.e. large firing range, thickness is less
critical etc.). And with the lack of expertise at rec centres someone in
that situation probably doesn't have much of a clue where to start. And if
you only have a few hours a day or a week to work on something that is a
hobby, then Amaco glazes are probably worth the price.

(And there are plenty of people on this list who have posted about how even
many colleges have degraded the craftsmanship and technical knowledge
portion of ceramics in favour of pushing artistic boundaries).

Are there people selling pots with expensive purchased glazes? Absolutely.
But they're probably not trying to make a living.

There are lots and lots of downsides to making your own glazes.

1. The really bulletproof homemade glazes are pretty boring. Things like
floating blues take a while to get the hang of.
2. Even a fairly modest glaze kitchen takes a fair bit of storage space. A
hobbyist in a small garage (let alone in a city where space is precious) is
already feeling pretty cramped with a wheel and kiln and table (or two).
Add in a few glaze buckets, then where do you put those bags of Custer, and
silica and whiting and Gerstley, oh and this glaze calls for dolomite, and
this one needs NephSy ...
3. And when you're just starting out, who wants to fire a kiln just for
tests. And we all know that if you make up an untested glaze and put it on
your precious pots, it's NEVER going to end well! So where do you start ...?

Considering the difficulties inherent in glazing, we should be a lot more
understanding of the difficulties rather than just sitting in snobby
judgement of people using easy, bulletproof commercial glazes.
If you look at the archives, when this list was truly active there was
probably a request every 3-6 months for a truly clear, craze free glaze.
And of course that's going to depend massviley on the clay body. And we all
know that "Cone 6-10" bodies (clay companies should be burned at the stake
for that one!) don't really vitrify very well at Cone 6 ... which leads to
crazing problems. Honestly when you think about it, it's absolutely amazing
that anyone that comes from a rec center, or a dumbed down college class,
gets started at all!

(Please note: I have a tendency to make gross generalisations and use
plenty of hyperbole to make a point. I'm sure YOUR local rec center is a
paragon of virtue ;) )
