#91863 Cone 10 Clay Contamination With Cone 6

Posted by Wyndham on 02 September 2015 - 08:42 AM

try putting a test piece in cone 10 firing, it might shrink a bit more but it will vitrify. Put a bit of extra kiln wash where you'll place the test in case it wants to fuse to the shelf. Should be usable, just test. If you are firing gas for cone 10 just place it in a cool spot in the kiln.

Turn them upside down while drying to keep from wrapping after cutting. Give it a try

#73075 Anyone With Experience Firing An Olympic Updraft Kiln?

Posted by Wyndham on 08 January 2015 - 11:24 AM

I started with an Aim updraft 10 cu ft kiln with 3 burners in the center bottom with a bottom shelf about 6 in above the burners. It worked fine for bisk and could only get to cone 7-8 with bottom hotter than top for glaze firing, it was a great learning tool.

If possible find a manual on the internet or call Olympic for instruction on firing,and shelf placement.

There's a learning curve that is going to take some time but it's only Gas($$$) and pots($$$$) and time.

A gas updraft will work well and not fall apart on you as long as you are reasonably careful.

Study how they fire their kiln, ask question, take notes before you head off on your own.

Trimming allows you to find the piece within the piece that you've thrown. This is the time that the true beauty  can emerge from a rough form. Feel the piece as it  develops don't rush it.

#68589 Exploding Pots During Glaze Firing

Posted by Wyndham on 25 October 2014 - 01:17 PM

A test would be to put an unglazed bisk piece through the glaze firing and see if anything happens.

If it cracked or exploded, the clay is the issue, otherwise it's the glaze or the method of glazing

Indubitably it does :)

#67279 Help! Hand-Dug Clay Needs Additive For Strength

Posted by Wyndham on 05 October 2014 - 12:15 PM

you might try bisking some of the clay, hammer it and sieve it to fine sand size or a bit coarser  and adding it back into the raw clay much like grog is added to other clay bodies.

It should give strength an the color would be the same

hope this helps

Dry screen the spod as you weigh it out., that way most if not all will wet screen later in your final screen.


#66263 Leveling the Wheel

Posted by Wyndham on 17 September 2014 - 09:04 AM

A quick test to see if yur wheel is out of level is to clean the wheel head then put a small amt of water in the center. You'll see where the low point is and the faster the water goes the more the wheel is off.

I've had to change from standing to sitting because of hip issues and seem to need to readjust wheel height about twice a year,up or down a bit and level


#65860 Have You Ever Done A Crazy Experiment Just To See What Happens?

Posted by Wyndham on 09 September 2014 - 02:33 PM

Yea, I took a pottery class, quit my day job and been up to my eye balls in clay ever since :).

I figure it'll be another 100 yrs before I figure out if it was crazy or not.


#65374 Trouble With Dried Out Glaze

You might also put the material in hot , almost boiling water to dissolve the soluble salts from the frit plus other stuff that may have formed.


#64928 Do You Donate Your Work For A Worthy Cause?

Posted by Wyndham on 22 August 2014 - 08:38 PM

Donate to local fund raising for medical issues. When the charity drives a better car than I...red flag.

Once I had  folks from a nearby city seeking donations to send their children to Australia to experience a different culture. I noticed their car was a Lexus.

Worthy charities outside the area, I'll offer 50% off. Some understand, Most don't have a clue what it takes to make a living as an artist.


#64265 How Much Testing Or Tweaking Of Glazes Do You Do?

Posted by Wyndham on 10 August 2014 - 06:16 PM

Testing is part of every firing, gas, electric, anybody I can get a piece into their firing.

My gas firing is the most active for testing because I can expect some major changes with small ingredient changes.

Test for changes in % of copper in copper reds as well as fluxes in those glazes.

With the thread on the temoku & leaf bowl discussion, I have some thoughts that I want to see where that may go.

If all I have to do was glaze mugs with the same glaze day after day, I'd go crazy......


I got the testing bug when I used to rummage through Harding Black's boxes of glaze test and notebooks full of his cryptic recipes and comments.

Toward the end of his career, I asked him about a test bowl of his that was great but not marked with any info. It was both a funny and sad moment because his memory was starting to fade.

When I asked,He said, "that's  beautiful , who made it?"

So many test, so little time.
