Quite likely they are chrome covered tin. Don't fire them. Poisonous gas. Roll out a slab of clay, cut the shapes out with the cutter to make tiles with holes in the center, cut each tile in half, dry, bisque fire, coat with kiln wash and fill with frit. You need to cut the tiles in half or thirds s...

Re: sculpting wax
Have any of you tried using Scupt-a-wax? The company representatives say that its "wax", and melts out cleanly for lost wax moulds, but it is more oily than waxy and is opaque. It feels great in your hands for sculpting, unlike my experience with microcrystaline. I wouldn't want to use it...

This is one of my favorite rants. Shape, color, pattern, texture -- all the formal elements are important. I agree with the guild. If you are using a shape that you bought in a store that anyone else can buy, why should you be considered a craftsman while others using that shape are considered newbi...

Re: Pot Melt
Unless it's Inconel the stainless will spall off black crud into your glass. Normal stainless is fine for slumping but won't hold up to casting.Steve Eshbaugh wrote:Is there any reason why you can't use a stainless steel funnel to

It is probably sugar. Lots of refractories, especially fiber boards and papers, use a sugar binder that is burned out at about 600 F. Smells sweet whene fired. I haven't heard that it is used in fire brick, but maybe so. In one of the pictures you can see the corner of the fiber board of the kiln li...

One thing that complicates the calculation is that the IR doesn't radiate just straight down. Parallel element's radiation overlap each other. Many of the better large, commercial, fiber, bell kilns, like the ones from the Czech Republic, which use coiled elements, in tubes on the ceiling and one al...

You are not mistaken -- glass will not thermal shock above 1000 F. That is not to say that all of your glass is above 1000 F just because your thermocouple says that's the temperature of the air in your kiln. If you are getting thermal shock in a 1/2 inch thick piece after going up at 35 dph then so...

You can stretch MM6 by backing a painted on face coat with plaster/silica if you want to. Two coats MM6 with drying time in between should be enough if your backing it up. The easiest way to paint it on is to run it through a blender first. That will make it very liquid for a while. For an open face...

It is hard to imagine what your shape is like and where the right angles are. I made some rectangular boxes with two inch high, 1/4 inch thick walls, where the top of the walls were buried in the bottom of the mold while the bottom of the box was exposed to the air. So to cast them the glass started...

Silica flour is finely ground quartz. The schmott he mentioned is apparently what we call grog -- fired clay ground up. Most clay is primarily alumina and silica in various propportions so I bet grog would work just fine. Do some small scale tests. You can also use olivine sand instead of silica, wh...

The Czechs can charge by the pound because they specialize in huge stuff, like Karen LaMonte's work. I think she's going to get hosed if she charges by the pound for green beans. I would charge for the job as a whole by figuring up the costs including anticipated failures and adding profit. I wouldn...

Ceramic molds can be used several hundred times, but probably the best material for multiuse casting is brass. If you can make a ceramic mold, it's not a big step to making a brass one. If you want detail, you'll probably have to use some mechanical means to press the glass into the mold. Gravity i...

I pay my guy $100 per hour and he's worth every penny. Once things are set up, the pieces go into and out of the set pretty quickly and it's not that expensive.
