I wouldn't go that far.. if you can post some clearer pictures perhaps, I think there are plenty of ways to texturize and affect glass in ways that would, at the least, get very close.Ultimately, if the only way to achieve the affect you are looking for is through acid etching, there are likely professional shops out there that specialize in it.. and whom could do it safely.

There are probably, within the translucent part, differences of 1/8" or more. Perhaps I should put another picture up? Sure. It won't change my opinion about you searching for HF though... because I care about all my fellow forum posters ;-) I have been told from about 4 people who have looked it it is has been acid etched and not with a cream, the real stuff. They could be right (as I said in my second post to you)... but I don't think you get how important it is that you don't go searching for HF yourself.Cheers,Donovan

	So the gold-colored part of the window that looks to be foiled is actually the part you are talking about (and the gold is probably something behind the window creating that color... so that part is relatively translucent).. O.K.Like I said, the pictures don't allow an easy analysis, but if the gold-colored part is what you are talking about, I'm now thinking it may have been glue-chipped, then perhaps cream etched.Glue-chipped glass can make a variety of patterns.. here's a google images search for glue chipped glass.Just a thought... but really, if you are not well versed in chemistry, don't try finding HF acid. Boyke is probably not responding because he's probably in the hospital. ;-)Donovan

	No, no metal foiling -- way too modern. House is full of leaded windows though. Too, the previous post with someone who did use the acid looks exactly like what I'm trying to do. If you look at the zoom of the two picture I put up you will see the glass that has been etched is in no way flat and not sandblasted. I have access to sandblasting and already tried -- way too flat and not at all what I am looking for. Have tried etching creams and powders -- not strong enough. So wish the guy who used the acid would write to me. He's got the answer I think.

	P.S.. regarding your windows. It is still difficult for me to tell from the images the makeup of the glass and how best to reproduce it. It appears that there is some metal foil'ing as well.Good luck, and feel free to post some pics if you do reproduce it.Donovan

	Hello Judith,I'm certain that purchasing Hydrofluoric Acid is not the way you want to go. ;-) learn about that kind of acid.On the contrary, I think sandblasting (which is a general layman's term for "abrasive blasting") is a better way to go. What most people think of when they say "sandblasting" is a grainy looking texture.. that does not have to be the case. Using pure 320 grit Silicon Carbide will have a nice satin sort of look. You can also experiment with sealers over the blasted areas.. such as "liquid luster" for a bit more see-through look.The glass you have in your old home may have well been made with acid.. even hydrofluoric acid, but that is not what I would suggest for today's use. We are hopefully smarter now with better alternatives.As an option, you can find etching powders and creams, but read the instructions and abide by the safety precautions if you play with those.Donovan
