Re: DTC 800

They also make the RTC 1000. You might want to look at that one. Typically, Bartlett supplies the board attached to the front of the controller. You need to add a separate power supply. They will give you the spec. http://www.bartinst.com

You can mix the medium in yourself. It's not hard to do.

Re: Imprints/Flat slumping

I use finely ground alumina hydrate instead of dry plaster. For the bed to make the imprints in, I use a mixture of sand and alumina hydrate, about 25% alumina by weight. I would use alumina between the sheets. I have done this, just as I describe, and then resin laminated the 2 sheets of 10mm float...

Re: How to Calculate Shipping Charges?

The best deal out there for shipping heavy stuff that manages to fit in the box is USPS flat rate boxes.

On the other side, I know people who will only ship USPS overnight, for a minimum of handling.

Re: Viewing window in homebrew fibre kiln

My first kiln is a front loader just a bit smaller than yours. The door is made of a combo of mineral wool covered with blanket (interior surface) with an expanded metal skin. I cut a round hole, about an inch and a half in diameter, in the expanded metal and insulation, and stuffed a wad of blanket...

Re: Viewing window in homebrew fibre kiln

Just cut a hole and slip in something like a brick, or a wad of fiber blanket. Pull the plug out and look in.

2" of fiber blanket is under insulated. It must run hot to the touch. It will work though.

Re: large kiln

Fiber all the way. Brick floor is acceptable. I just built a kiln a bit larger than you are looking for. What is your budget? Message me to talk more about it.

Put a straight edge over your shelf. I suspect you will find a dimple under the place where the bubble blew up.

Re: CaN A PIECE BREAK BECAUSE OF BAD ANNEALING???

Stress is stress, regardless of where it comes from. Stress is cumulative, so adding a little bit more can cause a crack. If you have compatibility stress, combined with annealing stress, and you add a puff of cold air to it, your result is not a surprise. Many years ago, I was trying to cut the thi...

Re: Slumping small and large projects together

On a second thought, I did all draping together, and will do the slumping separately. Don's opinion was supported by many colleagues- and I will post photos. I think this is a good strategy. Draping is not always supported, so the glass can keep on stretching and sagging. Slumping in to a mold is d...

Re: Slumping small and large projects together

There is a point at which you have heated the glass too much and it will begin to fall down the sides of a mold. Until that point, the glass will slump or drape, until it hits a solid surface. Float glass is far more forgiving than the fusing glasses. I often fire float glass in bowl molds as hot as...

Re: Help me, please

Hello every body, I broke a piece on which I have worked a lot. Tough! I glued it together, and it is now being fused. It seems to me , that there remained a 'scar' a mark that shows that there was a break there, even though it is probably fixed now. My question is - Is it possible to do something ...

Re: Frosted Finish Glass Paint / Enamel

Valerie, That's not it --- it looks like it might have some interesting affects but the temps are somewhat higher than I usually go. Bert, I tried to Google things before I posted a question --- but after I googled your satin etch --- I came up with a Reusche product. It has a fairly wide firing ra...

Re: WORKING WITH LIQUID ENAMELS OR GLASS PAINTS

Thanks Bert, A nice piece! I must insist do you PRINT on the glass or paint on it??? I do not paint but PRINT. I believe it is different. And IF you print, has it happened to you that you fired a piece MORE THAN ONCE, with the print on it, and it was not harmed??? Ferro Samba? THanks, Havi I don't ...

Re: WORKING WITH LIQUID ENAMELS OR GLASS PAINTS

Bert , is there a special benefit by firing upside down - the print on what would be the upper side of the piece later? Does it relate to surface tension??? i.e. the color will not stretch or something? [the wafers do - they stretch, being fired on the top , but would not stretch if they are fired ...

Re: Frosted Finish Glass Paint / Enamel

The product you are looking for is called satin etch. You need to make sure you are firing to the recommended temperature. Satin etch is basically a clear glass frit, possibly with some white alumina hydrate powder added. This frit is fired to a temperature hot enough to make it stick, but not hot e...

Re: WORKING WITH LIQUID ENAMELS OR GLASS PAINTS

Havi, primarily I use Sunshine series that I mix myself with micas. I usually work in a single firing. Often I can get away with a single firing that vitrifies the paint and does a slump. Most often I am reverse painting and firing paint side down, so the painting comes out under glass. I like to us...

Havi, I have been screen printing enamels on glass for some 30 years and I have found out that the glass enamel itself is only a small part of the overall complications. I started out as a printmaker too and have found that the complications of screen printing on glass are many. Your screening tech...
