Thanks Jen. I do miss the banter we had here, as it was a unique set of people who came together over the common theme of english speaking kiln fired glassies. These days there is plenty of banter over on Facebook. Rosanna and I responded to a political comment by Barry just a couple of days ago. I ...

I checked the oil. The plug has a dipstick type indicator and it seemed to be up to the bottom line. I added a bit of 30 weight non detergent oil that I had in my stash of stuff. That seemed to be the recommended standard. So I put the power back on. In the beginning it was making some "mechani...

Thanks Don, I would have guessed that mine was oilless however I did find the screw out plug, so I'll get some 20 weight oil and put it in. My compressor is in an unheated shop, so I need thin oil in the winter. With any luck the compressor piston rings aren't dead. We'll see. It hasn't cost much to...

I have a 6HP single stage compressor (big tank) in my shop that has been up to pressure for about 20 years. I don't spend much time in my studio these days. I made the mistake of leaving an attachment on my quick disconnect fitting, and it leaked. Several days later I went in to my shop and it smell...

Ethylene glycol is regular antifreeze. Propylene glycol is non-toxic antifreeze often used to winterize RV's and heating systems. I buy it as food grade from bulk apothecary, online, Recon requires a palette knife on a glass palette. I use a cake spreader that is pretty stiff for my palette knife, a...

I wouldn't add water. I'd add propylene glycol. Maybe soak the tips in the glycol.

Mullite is certainly more dense than any vermiculite board. So, mullite will heat and cool slower.

I generally anneal regular float at 1000 and I use 1030 for low iron.

PPG Starphire has a COE of 90, but is most certainly not compatible with Bullseye.

As to vitreous colors, you fire according to the colors, then anneal according to the base glass.

Vermiculite boards come in a variety of densities and thicknesses and are not smooth on top. Mullite shelves are smooth and dense. Both can warp, V-board is probably more prone to warping. Both tend to stick to glass. V-board is probably more prone to sticking. The more mass you place in your kiln, ...

If I were challenged to cut a circle out of a hard kiln shelf, I'd take it over to the waterjet shop and have them cut it out, perfectly in a few minutes.

and, Barbel... you are superwoman in my mind

Best, Dana

Plate glass pliers is a pretty broad term, so I'd make sure they are the same ones. These are running pliers. Most plate pliers are not.

What brand/model are these?

They used to be called PPG running pliers

It is true that pieces under an inch in diameter will anneal faster than pieces with larger mass. What would you actually gain by eliminating your 4th step? The glass is always hotter than the air during the cool down. I don't know if you can get away with that or not. Look at tutorials by Barry Kai...

I agree, But I have found that this running plier is the best economically speaking. Also a Toyo "tap wheel" cutter is a great help. Jim http://ecx.images-amazon.com/images/I/319JEn6HIBL.jpg The strip cutting principle that makes it easiest is to cut pieces of glass in half. So if you hav...

I have trouble cutting 3mm glass but 6mm, 10mm, and 12mm are easy to cut in strips using this cutter. My everyday glass is 10mm thick. http://cdn3.volusion.com/dgrwk.sauvh/v/vspfiles/photos/TC21SVR-2T.jpg I use these running pliers for anything 2" or wider http://cdn3.volusion.com/dgrwk.sauvh/v...

A steel wheel might be good for 10 or 20 circles. A Toyo or Silberschnitt carbide wheel might be good for 10 or 20 years.

The Silberschnitt with a single carbide wheel is good. The cheap one with the 6 wheel turret is horrible. Think about it. How do you know it is time to change wheels? That would be after a piece of glass breaks. Maybe cheap float glass guys can afford to lose some glass. Expensive glass cutting is a...

Fire float glass to a maximum of 1420ºF, and you will never get those bubbles. The glass gets viscous enough to blow bubbles around 1450ºF. Take as long as you need holding at 1420 to get your work done.

If you line the dam with 2 pieces of thin fiber paper, and the inner piece sits lower than the glass is thick, this will mitigate the tendency to make the spikeys. In other words if the glass is 7mm thick, make the inner lining 6mm high.
