That's really quite successful for a first cast. Congratulations. I haven't used System 96 to cast so I can't answer the question on the color change. You might try their casting billets or I can recommend Bullseye 1401 as a casting glass that stays very clear. If you have room in your kiln to put a...

There are a lot of reasons to back up besides viruses. Like mechanical stuff. This weekend my track pad button on my laptop broke while I was on the road.

The chair is marvelous. In my eyes it looks like a laminated form. Btw. Who is the US guy who *casts* furniture in glass. A huge "flowerpot kiln" with the mold velow. I think it was mentioned here a year or so back. -lauri That would be John Lewis. He uses lots of glue as well. http://www...

Pizza. Shrimp on slate. Really. Heat it to at least 700, pull it out of the kiln and fry marinated shrimp on it. Try this Brock: Shrimp on rock salt. Pack rock salt about an inch deep into a pan. Smooth top surface. Heat and cook, flipping shrimp once. Has to be rock salt, not kosher or fine salt. ...

Well, well. I haven't been online, because I have been dealing with what showed up with the firings...turns out it wasn't the firing schedules that was making my pieces curve. No, no. The support structure on the bottom of the kiln (1/4" thick I-beam steel) warped. Yep. warped up 3/8" in ...

If you take your stainless sheet to a sheet metal fabricator they can cut it and roll it into a cylinder for you. They can also weld it together or fold the ends so you can overlap them and hook them together. Shouldn't cost very much at all.

I don't think anybody makes a clamshell this small. I doubt anybody even makes a kiln this small with elements in the lid. The distance from the walls to the center is so short that heat is not that uneven. It is easy to adjust for any uneven heat in a small kiln by adjusting your schedule or layout.

Bert I did a casting workshop with Berteil V. some years ago and have his sand mixture on paper - will post if you need it but he adds only 5 percent bentonite well mixed into the sand .

You might look at John Reyntiens' class at Pilchuck this summer. His work is based in leaded techniques, but he has also branched into many more contemporary forms. I wouldn't be surprised if you could contact him directly and ask how much he will be covering. He's a very easy going person. Take a l...

If you are new to working with plaster, it is very much worth your time and money to go to a ceramics supply store and get a simple book on making plaster molds and read it. It will save you many times its cost in time, frustration, clean up, materials and real money. Just looking at the pictures wi...

If you're going to keep firing on the floor of your kiln you might as well disconnect the side elements. They are more of a problem than a help in that arrangement. I think everybody should be able to look into their kiln and should do so often, every time they make a new type of piece and until the...

OK. I did change the firing schedule. As I was loading the kiln this time I thought that the edges of the glass were too close to the sides, so I only did two pieces instead of three and I centered them in the space. The top elements are 18" above. Since the sides that are "down" are...

OK. I ran the firing last night. The pieces look good, with nice crisp lines, and they are NOT FLAT. They are bowed in the middle by about 3/8". My theories are: 1. Since the edges that are down, are the ones nearest the side elements, there is some uneven heating happening in the kiln. 2. My ...

What you're seeing in restaurants is probably Starphire. If you call PPG they will tell you who their local distributors are. It is also possible that what your seeing in restaurants is normal old float with moody lighting. You can minimize the green cast with a colored light. Flourescents make it w...

From what I understand of boats, a spinnaker is the triangle shaped sail in the forward section of a sailboat. So when you say, "like the front of a sailboat's spinnaker," do you mean a tringular shape that, when lying on its back, is taller (thicker) in the middle than at the sides and t...

The devit layer is about 1 mm thick between clears.

Now I got a grinding tool. Wonder how it looks if I
polish away the outer devit layers

Look up Brian Blanthorn's web site, especially the bowls. He has done lots of controlled, layered, polished devit work in the past.
