Akua, since you mentioned casting I do not think your mold needs to be drilled. When casting you are fully melting glass to a fluid state which conforms to the mold as it fills the mold. In most casting applications the glass is either in small pieces or dripped into the mold in a fluid state which ...

Lorelei, to determine the coated side of your dichro place a sharpened pencil point. tooth pick or other small thin object against the side of the glass that is up when you start. Look at the reflection of the object in the glass. If the reflection touches the point of the object the coated side is ...

I like the back side of my jewelry items to be smooth and shiny so I borrowed Bert Weiss' recipe for kilnwash and purchased alumina hydrate and kaolin clay from a local ceramic supply house, mixed it 80% alumina/ 20% kaolin, by weight, made a thin mix in water and appled several coats to the kiln sh...

Barbara, does the location and shape of the problem area have any relation to the size and shape of anything slumped on this mold in the past? Different glasses seem to affect kilnwash differently. Some seem to leave more flux in the kilnwash than others as seen by the discoloration of the kilnwash....

I don't much care what you call me just as long as you call me in time for dinner.

Best wishes,

I have drilled a drain hole in a bowl formed from about 3/4" thick System 96 glass by using a 1 1/2" carbide grit core drill from Home Depot in my drill press. I placed on the drill press table a shallow container large enough to hold a piece of 3/4" plywood slightly larger than the b...

The fact that your cab is in one piece indicates that the dichoic you used was 90 coe. If you fuse an item using glasses with different coe you get cracking or outright breaking of the fused item, not incomplete fusing. If it would work for your design you might try making the dichroic layer the mid...

On a Bridgeport slow and wet with tungsten carbide cutters but I would be afraid of contraminating the lubrication system with the abrasive cuttings removed from the shelf. Not at all like metal cuttings. I you have access to a surface grinder with dust collection I would rather try that. Best wishe...

I have used cherry red, chrome green, and opaque blue in sizes 2 and 3 on 1/4" float, no experience with powder or confetti. Fired to 1500/1550 and got good results. I mixed with just enough clear fyre to hold the grains together and packed it into a stencil about 3/32" thick. The only pro...

Measuring the distance from one rim of the mold across the top of the mold to the opposite rim with a flexable tape measure will give you the maximum diameter circle that can be draped on that mold without folding over the edge of the mold if it is supported above the kiln shelf. Cutting your circle...

Anealing is not a temperature or holding the glass at a temperature for a given time. Instead, anealing is the gradual cooling of the glass to relieve the stresses in it which have been caused by heating and moving the glass in the kiln. The "anealing temperature" ( 1000* F. for float glas...

I get the best results fusing float glass by placing the tin side of the bottom layer against the shelf, decorating the air side with whatever I am using, placing the air side of the top layer down against the air side of the bottom layer and coating the top and edges with a borax anti-devit solutio...

Camaro, you don't say where in Texas you are located. I am in Houston and have had some luck looking in the yellow pages under "Scrap". most of the dealers listed there are buyers of scrap metals. Some of them will sell to individuals while others will not. Even if they do not sell to indi...

Since glass shrinks more than ceramic bisque upon cooling I am concerned that if you slump glass over the face part of your bisque mold and allow the glass to go over the edge of your mold you run a very real risk of locking the glass onto the mold or having the glass crack as it cools. You might be...
