In Topic: White Glaze Issues.

Yesterday, 11:56 AM

I'm thinking to widen the firing range a small bit

you might try to tweak the glaze by taking  your Cornish stone down to 25-27 and upping the soda spar to13 to 15 to get a smoother melt with out movement, just a starting point for testing

In Topic: How Fast Do You Run Your Wheel When Centering?

19 July 2014 - 10:48 AM

The faster the wheel  the more centrifugal force pushes outward against your hands. By the end of the day I use more speed, am more tired and slop more pots as I fight the wheel. 

BTW a high speed wheel makes for great spin art without having to go to the county fair

I also I visualized   a 57 Chevy engine/ drive train/w rear end hooked to my wheel, remembering the Top Gear episode where they hooked up a car engine & transmission to a food blender, but I digress :)

In Topic: Wiring For An Outlet For A Kiln

If you have room for additional service on your breaker box, I'd have an electrician put in a designated line. Much better with your insurance company. You may need a designated box.

Most definitely, which you will learn as you gain experience as a potter using electrical kilns.

In Topic: Pin-Holing In Standard 112, But Not B-Mix - Help And Opinions!?

13 July 2014 - 04:35 PM

There have been post about the goldart clay used in some of the different brownstone clay bodies. It seem that some may have more organics/coal particles in the clay than it used to. This may or may not be true. One idea is to create a bisk firing schedule that allows longer burnout time in the 1100 deg f to 1600 or 1700 degrees range.

You might look at your kiln controller manual and find what the bisk schedule is and make one with longer firing times between these 2 temperature areas.

If the program calls for 200 deg/hr in this area, make a custom ramp/hold that slows it down to maybe 100 deg/hr.

I'm sure others here may have a better heat ramp suggestion than I.

Just a few ideas

You may also have issues from time to time because the slop clay will change with different people using different clays and amounts, maybe a little, maybe a lot.
