I had a small project today that got Museum Glass, and I used a piece that I had wrapped up some time ago and put in a scrap bin. I noticed that it had a very pronounced, blue-ish reflection from its surface. This was true no matter the angle or lighting in various parts of the store. I compared it to a known current piece, which had only a very subtle pinkish reflection from very particular angles. I switched the glass in the piece to a newer piece and it looked 100% better.

Have they actually changed the coatings on MG, or was the older sample from a funky batch?

I have a small pastel at home framed in MG that gives me "the blues" too. I'm going to bring it in Monday and replace the glass with the newer stuff.

I have only ever noticed the purple/green colors with Museum glass - fine on something dark (like their samples) but hideous on light colors.
 
It's not a cleaning issue. I didn't have to clean it bec. I was wearing my special gloves from Grainger to handle it. It's an older vs. newer thing. They seem to have similar edge color, but the optical properties of the surface are very different.
:shrug: Rick
 
Some batches are just funky. I had a box recently that had such a greenish yellow tint to it that I couldn't even use it. I originally put it on some art that had bright white matting, with the mg glass on it the mat looked canary yellow, no joke
 
I noticed the same thing too.
If its anything like matboards, the manufacturer's probly changed. I used to work at one of the major matboard manufacturer's and the labguys explained to me all about how the vendor calls all the shots. They were constantly testing every roll that came in for consistency and subjecting them to standard tests, not just new products, but each and every roll had to match the standards that they kept in a refrigerator. When something began to vary too much because the vendor changed their product, the mats were often discontinued. The number one reason for mat discontinuation was vendor change.
So if the museum glass is anything like mats, someone along the way changed their formulation.
Personally, i like the blue hue better, but so long as it is protecting the same if not better, i'll settle for orange.

My regular boxes of MG don't seem to have the blue effect. This was an older piece I had had around for a while, and the frame at home was done a while back. It's not just the blue tone, but isn't the point of MG to cancel the reflection altogether? As a customer, I wouldn't be happy if I paid for "no" reflection and got a "blue" reflection.

That is the reason I have never been fond of Museum Glass - what good is no reflection if what you see has some awful color tinge to it - doesn't that kinda cancel out all of our careful and sometimes tedious efforts to design perfect matting packages?

I think I'll stick to reflections.
 
I've always pointed out the 'blue' reflection to people and practically no one minds it. And I tell them that no matter what kind of glazing is used, it's still going to reflect light--every surface does and there's no way of getting around it. Museum glass and non-glare (which is a misnomer) are options available to them that reduce what I call a 'white light/mirror image' reflection. I've found that the people that buy it, are doing so mostly for the color clarity (reduced iron content) and not the non-glare or UV protection.
 
I dont think I have sold a single piece of MG that didnt have that purple haze to it. I only see it when it is flat on the table. Upright, I dont see it.

Funny tho, I have 4 different TV promotional displays, and none of those have that haze.

How does TV reflection free compare to MG? I have never ordered it.

If you mean AR glass, it has the same surface coating, but no UV filtering.
