In Topic: My Thoughts On Element Life

18 May 2017 - 09:31 AM

I just attempted a ^6 firing in my very old Cress B23H. It was an inherited kiln that was supposedly maintained on a monthly basis. It was owned by an 87 year old ceramist who gave it to me when she got a replacement kiln from a friend. I've used it for bisque and low fire glaze firings up till now. The ^6 firing failed at 2117 degrees F. The controller had a "Firing too long"

message. I am guessing that the elements are old and tired and only reached ^1. This was actually a test firing to see if the kiln would reach ^6 before I sold it. 

The question here is...would it be worth replacing the elements at about $170 for the set and selling the kiln, or just getting rid of the kiln. I have a ^10 Cress waiting to replace the B23H. It too is used, but in much better condition. I will probably be using it at ^6 for the rest of its life.

Any thoughts?


In Topic: Advice For Centering Clay - Slipping

Most of the time I use non absorbent bats that I have recycled from a previous life or rescued from the trash. When I was in the remodeling business I had access to formica or corian sink cutouts. They were usually big enough for 2 round 14" bats. The formica bats had a particleboard core and I sealed the bottom and edges with 3 coats of Diamond Varathane or a polyurethane spar varnish. If you don't seal them, over time they will swell and become useless. The corian bats were waterproof to start with, so there was no deterioration with exposure to moisture. In either case you have to use them dry or your clay will definitely slip with too much pressure.

Usually talk radio...until I start yelling at the radio. Then I switch to an Oldies station or throw in a CD where I have total control. I don't like to anything in silence except read.

thanks, neil.  you gave me an idea mentioning the angle grinder.  i have one but only a masonry round thing.  (senior moment)  can i use a diamond one and cut out a space big enough to avoid the protruding thermocouple covers and leave an extra inch around one?  it just seems a shame to have to put a 3 inch post so  i can miss the thermocouple when the work on the shelf will fit with a 1 or 1 1/2 inch post.


Try a dry-cut diamond blade on your angle grinder. You could cut a slot in the shelf to clear the TC and finger grooves if you don't want to cut the entire shelf.


In Topic: Gray Areas In Fired Glazes

I find speculation on what may cause something to happen in a kiln interesting...

after a glaze firing in my Ceramics 1 class a number of years ago I was looking on the shelves for my Christmas red vase but couldn't find it on the first go around. I figured it would stand out like a sore thumb. On the second look I found it...but it was pure white instead of red. When I asked the professors what happened, they speculated that the piece might have been placed in the kiln next to something that might have had magnesium on it. If I can remember correctly, the piece was fired in one of the schools electric kilns. It still remains a mystery as to what happened.
