Replies: 15

Another way to test the temperature in your kiln is with ceramic cones. Each cone is set up for a different temperature, so you can get some idea of how accurate or inaccurate your kiln is. Also, there's a lot of good information in Bullseye's "Knowing Your Kiln" TechNotes No. 1: http://www.bullseye...

Re: Kiln Wash Won't stick in mold

:?: I have a new ceramic mold and the BE kiln wash will not stick to one small spot. I even tried leaving a thin puddle over the spot when I baked it, but no good, it came right off. What should I do to make it stick? Hopefully, Ross You probably don't have to do anything. It's common for ceramic m...

Re: Distance from top elements to glass?

[quote="db]A thread a few weeks ago on craft web gave me the impression that there's a point of insulation thickness (I remember 6") after which it becomes a heat sink and begins to degrade efficiency.

Re: Distance from top elements to glass?

I've just had my big side-element kiln retrofit with ceiling elements, so it can be used as a top-broiler, so to speak. I'm using it to slump lots of small pieces of glass, on corrugated stainless steel sheet. Question: how close can I safely place the glass to the top elements? 6"? 4"? I'd like to...

I don't see how anyone can own the process of cutting a piece of copper and fusing it between two sheets of glass. The idea is obvious to anyone who's ever had a sheet of copper and a fusing kiln. As for Jackson Pollock's "innovative technique", he himself said that it was taken from Native American...

I'd be reluctant to use thin fire, for fear that it would curl and cause problems. I'd use a thicker fiber paper.

Has anyone tried this with thin fire?

For larger pieces you probably need to find a local welder. You ought to be able to get them made for $25 to $50 each, but it may take some effort to find a welder willing to take on the work.

Some rocks have moisture in them and will explode or crack when heated in a kiln. If you're going to try this, first prefire the rocks to see how they react to the heat.

The commercial embossing products are brass. Plaster won't withstand repeated use at the necessary temperature (1300 to 1400 F).

The jury's still out on that. My latest test firing got fairly severe bubbles.

I'll report more fully when I know more and can do a few more tests. And I'm sure Jim will let us know his thoughts, too.

I also am curious about how many of the WG board members went to Vegas. If I could figure out how to attach a poll to this post, I'd do it.

I will post my results as soon as I've finished with the various tests. Right now the company offers several standard sizes, the largest of which is 20" square and costs $195 retail. I believe that custom sizes are available, but they're not cheap. The product is about 1" thick, one side is smooth, ...

Actually, it's easier than using cerium oxide. You can just use cheesecloth to smooth by hand, or if you want something really smooth than use a buffer attached to a regular drill (or just a car buffer without the cerium). I've fired the sample shelf I have four times and so far haven't had any stic...

Couldn't agree more, Sara. There are a number of things about the company that worry me, starting with their discount structure to retailers (it's horrible), their sales materials (lots of mispellings and such), and the lead times to get the shelves (way too long). But the version of the product I'm...

No Troubles with Bubbles

brad - the fusion shelves - are they smooth? also what about bubbles on larger pieces? D Very smooth. No bubbles at all. My understanding is that when they first introduced the shelves they did have troubles with bubbles, but they seem to have solved that problem. I'm using a 12" square shelf, so d...
