I think because most (not all) people who fire w/ gas go to ^10 or
better in reduction. ^6 is mostly used by folks with electric kilns,
thus the oxidation glazes. I do have a recipe for a nice copper red at
^6R, but have currently misplaced the notebook that has the recipe in
it. I got it from somebody on Clayart tho, so maybe they will repost.

Recently there has been a discussion and promise of some postings of ^6r
glazes, for which I wait with a worm on my tongue ("bait"ed breath.).

I have been sending ^6 reduction recipes. Rick Malgrem also has a list
of ^6 reductions recipes. Where are you looking?

Jack,

It is my understanding that, with a typical electric kiln (not the "heavy
duty" or "professional" kind), cone 6 is the highest practical temperature
that they are designed to reach on a repeated basis. Most of the standard
kilns are insufficiently insulated and the elements provided are not of the
capacity required to reach cone 10 time after time and give reasonable
longevity. Sure, the manufacturer says they'll fire to cone 10--and they
will--but it's extremely hard on the elements and you'll be replacing them
very often, as well as paying for all that electricity. Thus, the
popularity of cone 6 which, with a properly formulated body and glazes,
will give results every bit as good as firing to cone 10.

Well, I know that the reason we use ^6 in oxidation here in Florida is simply
because we only have electric. Most often cone 6 is an option for potters who
want to use a stonewarte, but cannot afford (my case) or do not want the
hassle of gas firings.

My question to you is: Why drop down to cone 6. The effects that you can
achieve with cone 9 are much more brilliant. If you need any recipes, please
e-mail me back. I have tested most glazes and have been working on these for
the past three years at Flagler college here in St. Augustine.

Jack,

The reason is that most people who do cone six fire in a electric kiln. The
potters who fire to cone ten in a gas kiln for reduction have not found out
the benefits of firing to cone six or seven in the reduction atmosphere
(like lower gas bills, less wear on all refractories, less waste of natural
resources). It takes some work to drop your glazes down to cone six and alot
of potters like using the old tired and true glazes developed in the
sixties, they are rich and you just plunk and dunk.

I'm making the move from cone 9 to cone 6. But I'm a little puzzled that
all of the cone 6 recipes that I've found are for oxidation. Why is this?

Hi Marcia...I have not seen any on the list so far...?????

Dear Clayarters,
I have sent two batches of ^6 reduction recipes last week and more will
come. Richard Burkett is sending me an updated version of hyperglaze so
that I can easily transfer them to readable files for clay art. I will
be out of town for a few days for University business.
Will catch up some day, I hope.

Some people missed the previous posts:

Because I teach just half-time (two days a week), c/5-6 electric works out
for my community college classes. We're always looking for better glazes -
if you have any to share, we'd love it! Thanks so much!
