is cone 06 same as cone 6 ???

As a newbie, I ordered some cone 06 and cone 10 clay. Someone told me
that there is actually cone 6 clay that is not the same as cone 06 -- is
this true and what is the difference? I hope I did not buy the wrong clay!

There IS a BIG difference between ^ (cone) 06 and ^6.

If I read the chart correctly, cone 6 is fired at MUCH higher
temperatures than cone 06. I believe I ordered the correct clay, cone
06, rather than cone 6. I got the clay at Axner and they only had for
sale cone 04, 06, and 10 premixed clays.

O0ps, I meant I bought Cone6, not Cone06, and I bought Cone10. My goal is
to make my own stoneware dinnerware among other things, so I think I got
the right clay!

You wanted ^6 and bought ^10? You can definitely make dinnerware from that.

I ordered Cone6 and also Cone10. So I think I am getting the right clays
for making stoneware, etc. Those should both be nice strong clays when
fired, right?

Yeah, I did the same thing - for me it was the first time I bought glaze.
The good news was the pottery supply store exchanged both the clay and the
glaze I had bought for me.
I believe the difference is that cone 06 would be considered an
earthenware - still porous, whereas the cone 6 or 10 clay are high fire
stoneware - they fire to a much higher temperature. I'm sure someone else
in the newsgroup will give a much more thorough answer.
But yes, big difference!

That is correct. ^06 is what one uses to bisque fire,
^6 is what clay is fired to after glazing (though some
people fire earthenware to lower temps, but let's not
cloud the issue. ^6 is MUCH higher than ^06.
According to Axner's current catalog, their clay is
fired to ^06-02 (earthenware), ^6 for most stonewares,
and ^9-10 for porcelains.
Raku clay (which is a totally different animal) is usually
fired to ^05, except their "Max's Raku Clay" which can
go from ^05 to ^10.

^06 clay is not bad to start out with. Use it to get used
to throwing (like practice clay) or to figure out what your
wheel and skills are capable of in terms of height,
thickness, shapes etc. Have fun with it! That's the whole point.

Hope that helps,

You wanted ^6 and bought ^10? You can definitely make dinnerware from that.
You wanted ^06 and bought ^6? You can still make dinnerware.

You wanted ^6 and bought ^06? Make flower pots. ^06 is too porous, as
someone else has already pointed out.

Good Luck!

I made a similar mistake in a different area: Pure silica is a component of
almost all glazes. My first try, I ordered 100lb silica. I got a very
refined sandbox sand. I should have ordered the powdered flint (also 100%
pure silica)

Incidentally don't don't fire the cone 06 at cone 6 temperatures. You will
ruin the kiln. The 06 will turn to a runny glass mixture and spread all
over.

May I ask why you bought cone 10 clay? That is somewhat of a high fire for
someone who is new to this. Cone 6 would be a better stoneware range to
work with in my opinion. As has been stated cone06 is what you would bisque
fire your greenware to before glazing to fire to Cone6-10 (for stoneware).
What kind of kiln are you using? The manual it comes with should have a
very clear diagram of the cones and how they relate to temperature. Cone10
is pushing it for an electric kiln and is usually what you use for porcelain
or reduction firings.
