I just finished framing 3 pieces for an out of town friend. He wanted UV glass. Two of the three were clearly marked as to which side faced art. One piece was not marked. Having never run into this before, I called the place that sold the glass to me and was told that the coated side (unscratchable with a blade) faces the artwork. Well, that is what I did. My friend was happy with the work and headed back out of town. Now I found out that the UV filtering is on the wrong side! Dumb question, but, does it matter that much?
Thanks for yor help, Sam :confused:
 
The scratchable side is the coated side, and yes, it's supposed to go inside.

The UV-filter will be equally effective either way, but the coated side will show scratches from normal handling, and abrasion from routine cleaning.

How far out of town is your friend? If you can do it, arrange for him to bring back that piece so you can turn the glass over. Or, if he's waaaay out of town, maybe you should have a fellow Grumbler fix it for you. I'm sure any of us would be glad to take care of that for a small fee -- or perhaps a beer at the next PPFA meeting.

Avoid the problem next time by test-scratching a tiny spot that would be under the rabbet. On small frames we often use cut-offs from larger sheets, which do not have the identifying ink line, and that's how we determine which side is coated. It's quick, easy, and fool-proof.
 
Ummm..you could just take a visavisa pen and mark the score side before taking it off the wall cutter and storing it!!

if you have an unidentified or unmarked piece of cc glass, try this: steam up a spot on it with your breath, if it's smooth and even it's uncoated. if it's all spidery, it's the coated side.----go on, TRY IT!!

And if you breath on it, and the glass cracks, you need some help.

Sorry. I didn't get on line last night and I have a lot of pent-up sarcasm.

What's a visavisa pen?
 
Spray water on both sides of the UV glass and note that the water runs off on one side and puddles on the other as if waxed. Put the puddle side next to the art because that is the coated side.

I tink it is a dry erase, magic marker, sharpie type pen. I use one to draw a circle around the scratch on UV scraps. That way I am less likely to score the glass and then find out I have a scratch. Not un-likely, but less-likely!
 
I checked on Google and it says it's a creditcredit cardcard.

Like you, I use the Sharpie pen to circle glass flaws. That way, the customer won't notice the flaw itself. They'll just wonder why there's a black circle on the glass. If you put the black circle on the uncoated side (the outside) you can remove it and say, "There. All better."

Your customer will be dazzled by your quick, friendly service.
 
I have always been able to see the coating and know which is inside.

Hold the cut piece of glass up to a light and look across like you are looking for warpage in a stick of moulding. The side with all the bubbles is the coated side.


Then again, I have four eyes. And four eyes sees better than two.
 
Ron,

just grabbed a "sharpie" to mark the glass bubble I found in my TruVue UV (finding quite a few in the past three cases btw) and the pen isn't a sharpie, its a Vis-a-Vis overhead projector marking pen! The things you don't know you have!



Jerry, I held up a piece of glass like that, once. My grip slipped, it hurt, now I scratch the glass! Doesn't hurt as much, (and I don't feel as stupid when people look at me sans facial divots!)
 
Sanford's Vis-a-Vis markers are overhead projection waterbased markers that are great for marking glass. They come off clean with glass cleaner or H2O. They are not dry erase though. Dry erase markers would just wipe off with a soft cloth. Vis-a-Vis are available at your favorite big box office store and many art supply stores. They come in a number of colors and sizes.

Sharpies are tougher to remove and often it is easiest to get a sharpie off with a razor blade and glass cleaner. If you use the extra sharp size sharpies for anything, try a Pilot SC-UF marker instead. They seem to be blacker and "wetter".

Another item I use on a regular basis are Schwan Stabilo's 8000 series "All-Stabilo" pencils. They write on paper, glass, film, metal, finished wood mldgs, etc. They are great for marking mldgs and again will quickly wipe off with a little spit on your finger. They are not as good for marking glass as the Vis-a-Vis markers though. They're a little harder to find and probably most available through an art supply store. I carried them in several colors in my past life as an art supplier, but they may need to be special ordered for you through a large national distibutor like MacPherson's.

Dave I still carry the Stabilo's!~ Sign painters love them because you can write on glass then just wash it of with (spit

BTW when Dave refers to an art supply store I am sure he is referring to me!~ Right Dave!~ LOL
