Glass from hell

I was doing a rose window over the weekend and I got in a wrestling match with some Spectrum red ruby waterglass and it just about whupped me. I produced scrap on about a quarter of the pieces, having to redo some three times.

To be honest, it wasn't all the glass's fault. I'd been lucky with easy cutting glass before that and I got into bad habits like not doing preliminary cuts on concave parts. I also found out that I just about had to do just one cut and break at a time. Multiple cuts before breaking broke into the other cuts.

Anyway, this window is my third now and I can see the quality of my work improving. Very satisfying. I'm getting closer fits with less grinding.

If I ever do another rose or hummingbird window I think I'll scream.

**************** Haha! I'm happily walking through all the cliches. I've done an underwater tropical fish window, then a traditional victorian design, and now the rose. I've got a heron/cattail one coming up, and gotta do a fleur de lys or however it's spelled.

I have found with a great many people, their cutting improves when they stop trying to shove the wheel thru the glass. Ruby red cuts beautifully, if you don't treat that little wheel like a saw blade, or a knife. No matter how hard you press, it is not going to cut the glass. Lighten up your pressure and place a small controlled scratch with the cutter wheel, and it will practically jump apart where it is supposed to.

Like everything else in life, to get good takes practice. No secret tricks to it, know matter what a glass campus guru tells you.

************ Haha! Guilty as charged. When I first started I would almost come off the ground with the weight I was putting onto it. OK, not quite, but still you get the picture. I've heard that if you cut too deep the break will go anywhere. I have started to lighten up, but I imagine I'm still at about twice the pressure I should have on it.

Yeah, me, too.

About two years ago, I had the opportunity to collaborate in my studio with Mr. Javahut on a huge SG project that I had to complete under some tight deadlines. I've been in and around the glass business for a few 24 hrs now, and I considered myself a pretty good craftsman and pretty proficient in cutting glass. My jaw hung open as I watched Java cut down sheet after sheet of opal glass with nary a stray run.

I can tell you from first hand experience and observation that his "lighten-up" advice is what everybody needs to do. He taught me to listen to the sound the score makes. Different kinds (and manufacturers) of glass need different pressures to score properly, but the sound of a correct score is pretty similar. You'll know that sweet sound when you hear it.

Using a bathroom scale to figure out how much pressure you are putting on the glass is, well, just plain latrine advice. Believe what you are told by people who actually make a living in the glass business, not a discredited scam artist.

P.S....next time you have a trip to Atlanta, send me a private email. Maybe we can hook up?

In addition what Moonraker said (listen the sound) there are acouple of other cues.

- If you get any tiny schards, you are over pressing

- Look at the score. It must be a hardly visble clean line with no jagged edges

- After breaking, look at the cutting surface with a magnifying glass. A bad score leaves deep scale-like irregularities, a good score has onlu slight scales and the core of the glass is broken clear and straight

First of all red is one of the easier ones to work with. Next, I NEVER score and break more than 1 cut at a time. I've taught thousands..... "1 score, 1 break". I think that all those "relief cuts" are useless, and only make the area you're working with weaker, more prone to trouble, and later crack running when soldering. Sure there's always different ways to do things, but my way works everytime.

So now you are claiming that Bullseye stole "YOUR" idea? Bwahahahahaha!

Don't you have enough to do covering your tracks on you kiln sales scams without displaying your ignorance around here?

BTW, the "latrine" reference was because you are a shit head. LOL
