I would guess that these schedules are artifacts of an "ancient" way of doing glass fusing. Before the introduction of computers and digital controllers, how would you do a ramp? Probably by turning the temperature knob on your kiln in a number of steps. For example, a schedule might say &...

I use equal parts of: Plaster of Paris (from Lowes) Diatomateous Earth (swimming pool filter media from Walmart) to which I add about 5% kiln wash (Hot Line or Bullseye) It may not be "the best" mix, but the only exotic stuff is the shelf wash, which you should already have. This mix can b...

I have described one way of dealing with this in Large Rural Mailbox Annealer, or Annealer Temperature Management for Jacks http://www2.cemr.wvu.edu/~venable/rmi/studio/mailbox.pdf This is cheaper than an "infinite heat switch". By the way, true rheostats are seldom used as controllers now...

I've been reading a book on "Prehistory and History of Glass Technology." We know that much early glass art was kilnworked from pieces traded internationally as ingots. In the book it is stated that the crucibles in which glass ingots were made were frequently lined with lime. Also that in...

Most of the make-a-mold suggestions have been about ceramic molds. Nothing wrong with those, of course, but there are lots of other kinds. If you actually are a fused glass crafts master, I'd assume you own, or studied, eith Brad's Contemporary Warm Glass book or one of the others. These give good i...

Well, yes, if its NEW glass the Spectrum is flat and 96 COE while the Bullesye is textured and 90 COE.

The possible gotcha is that Bullseye used to sell very flat double rolled 90 which were reported produced by Spectrum under contract. (Sigh - I loved the 12 x 12 inch sheets of this glass)

I told him be email that I don't do it that way. I let the printer fuse onto a transfer medium. Some other experimenters have reported ways to skip printer fusing and transfer unfused toner. A potentially messy procedure at best, and it may damage a printer if you get it wrong.

Now you see why some of us buy torches and glory holes as well as kilns. Its not hard to make in SMALL quantities. Rudy Fritc teaught in in the kiln class I took with him, or you can take Loren Stump's flameworking class and REALLY learn ablut detailed cane.

There have been several discussions of various forms of "fused batch" and/or "cullet" made specifically for re-melting in the studio. Some of this is/was coming from China, and early buyers were getting product not really ready for market. Personally, at present I will stay away ...

I would think it is a toner issue. I have successfully used two HP printer toners and a Xerox toner. It is, of course, impossible for me to test all of the toners on the market. I would appreciate email (or posts) providing information on success or failure with specific products. Definitely works f...

"...different shades of black.." I assume you are asking if a grayscale image can be reproduced. The general answer is "yes." A xerox or laser printer prints a gray tone by creating a dot pattern similar to "half-tones. Old copy machines did not do this well, hence we had pr...

OLD window glass may not be "float." My general guess is that the change-over is post 1950 in much of the US. I was given some old window glass to play with, and couldn't master the technique of finding the tin side with a UV light. Then I bought some new window glass at Lowes - and had no...

I have only used "laser" decal paper. I think ink-jet decal paper might work, but that they have different sueface finishes. It is possible, however, the the ink-jet paper might melt in the fuser of the printer or copy machine. Both types pf paper cost about the same. If you have ink-jet p...

The "kiln" control is only one part of the virtuosity. That is "only" a matter of having a big enough brick pile to make cooling take place over several days. Imagine managing to get a variety of compatible colors without having any concept of COE, etc. I'm sure they had a good g...

A thermocouple in a kiln is NOT simply reading air temperature. In addition, it is being heated by radiation. If it can "see" elements, the total it indicates might be significantly different. Think of a piece of black metal in the sun - it might be too hot to touch, although the air tempe...

Wow, 23 inches and up is pretty big. At that size the rigidity needed for a rotating cutter gets difficult or expensive. You dan't say how many of these you need to do, or what your expected investment level is. I'm happily cutting 12" circles with an $8.00 homemade device, and if I had to go b...

I've got a small compressor - I think about 2 to 3 hp and 12 to 15 gallon tank. I originally bought it to fill tires, spray paint, etc. I can accomplish a lot with it, but everytime I slowly work through a good project I can't help thinking how nice it would be to have a bigger unit.

Brock >>> I think you're waaayyy past student stage Wally. Hmmmm . . . Staying a student keeps me from aging. (Except in the knees and hips.) >>> . . so what if you loaded a color ink jet printer with enamels? NOT IN MY PRINTER, YOU DON'T... Seriously, it's a great idea. Some of the clay ceramics ty...

I've posted a .PDF handout on my process for fusing images to glass at http://www2.cemr.wvu.edu/~venable/rmi/studio/xer4jac.pdf This handout reveals the techniques which I taught in the Xerography In Glass class at Corning last October. I'll be away from my computer next week, but will consider ques...
