Tempered glass geek in the house

Does anybody know where can I get a tool belt pouch for my new microscope?

If this thread was on WCN it would be very informative and deep with scientific detail. It would be easy to read without a lot of off topic humorous posts. Nobodies feelings would be hurt. Gary would receive the respect he deserves and the thread definetly wouldn’t have over 6,000 hits.

Workers are just trying to do their jobs - but nobody tells them it really matters whether or not the roller side is defective.
Management doesn’t care enough to educate them.
This is why I go to the GPD conference in Finland - to explain a way to get their workers involved in roller side quality control, by actually checking tempered glass with scrapers in the factory.

By the way, I worked in a tempering facility that did not use furnace rollers - it was older technology where the glass was hung on metal tongs, 3 inches apart.
So unlike glass tempered in roller hearth furnaces (where the roller side could be bad) - both sides were always fine to scrape.

There is another newer technology without rollers where they use a continuous blast of air to keep glass from touching anything during tempering.
No roller side there, either - both sides are always fine to scrape.

It’s unfortunate for the consumer that some of us treat ALL tempered glass as if it would be unsafe to scrape. So the customer with Good glass receives less than perfect results for an inflated price because we DON’T want to get sued. That’s nice

Okay, just trying to stay abreast of the manufacturing end as well - the GPD conference in Finland; is that a national conference where manufacturers all over the world are meeting or just European? (Just not familiar with it.)

So I take it the rollers was a faster technology at the unexpected cost of FD? Enter new “blast of air” technology and that will hopefully replace that. And now with modern glass coating there is time delayed scratches too? Yet another flaw in manufacturing that we as user end maintenance have to protect ourselves from. If you know - what response do manufacturers have about time released scratch?

Possibly true Mike. But also respect demands respect. So, back on topic.

To which I should add; if there’s no roller side to worry about - as with the other tempering technologies I just mentioned - the marks wouldn’t tell you anything.
(Because there’s no bad side.)

If there’s noticeable distortion, usually that’s a good clue as to which way they tempered it.
(Because each technology distorts flat glass in a different way.)

Bah.

Coatings are not flaws.

They should be willing to sign waivers - if they won’t, it’s because they want to sue you.

Okay I missed something. What causes time delayed scratches, a change in the glass itself?

Gary: I never looked at a customers unwillingness to sign a waiver in that light before. For me that was one of the most important posts I have ever read in regards to fabricating debris. Thanks!

Good thing it’s on WCR then! Gary can use all the helpful humor he can get…and the high view count definitely is good for the industry.

I’ll bet Dangerous could make you one…

I realize you don’t want to talk about what you tell builders and homeowners about your abilities versus other window cleaners, so I haven’t asked.

But you really don’t need to be heckling - your support of heckling actually hurts your friends here more than it hurts me.

You did ask. I told you I wasn’t going to answer. So you rushed on with your arrogant assumptions. And that’s when I decided that even though your info is probably good, I don’t have time to fool with you.

Also, just because you like to use the word “heckling”… that doesn’t mean that everyone who makes a comment in this thread that isn’t addressed to you or that isn’t as self-important as your posts are is “heckling.”

First - coatings are not part of the glass, and you can scratch many coatings with a scraper - but I’m here to talk about uncoated surfaces.

And - I’ve posted about 140 times here, so I’m not sure what you missed - but I have discussed how tempered glass scratches grow, and I’ve posted links & photos.

You heckled a bunch of times before the day you mentioned your marketing materials, and you’re still at it.

Let it go.

Haha, you always have to have the last word. You fail the beer test, Gary.

Or don’t let it go.

You’re only disrupting and obstructing your many friends here - you really can’t hurt me.
