looking for a suggestion on small chamber
I have several A/C compressor housings out back and it occurred to me that if I could cut them in half a make a good seal they would make a good chamber. Does anyone have any suggestions on how to

Re: haze on mirrors?
Well, I spent a little bit of time in a physics lab where they working with high vacuum. The technique they used most often was while wearing rubber gloves, rinse with acetone and wipe off with

Re: haze on mirrors?
Judging by recommendations and videos I've seen, there are lots and lots of different ways of cleaning mirrors before coating!? ? Guy Brandenburg, Washington, DC?

Re: haze on mirrors?
I am very new to this vacuum thing, but I would guess that blowing water off a mirror would be a good way to finish the cleaning process, but apparently is not recommended. I've also been known to

Re: haze on mirrors?
If they have changed the treatment of the municipal water supply then a new chemical may be being deposited on the glass prior to coating leading to the haze. Option two (more remote) is that you have

Re: haze on mirrors?
I know this going to sound silly, but you are using distilled water right? If so then that just leave the paper and possibly anything that might get transferred from your gloved hands to those towels.

Re: haze on mirrors?

Re: haze on mirrors?
No, I don't. Never have, except for polishing & figuring. This phenomenon is recent. Not quite sure what you are trying to say. ? Guy Brandenburg, Washington, DC? http://gfbrandenburg.wordpress.com/

haze on mirrors?
Every so often, I am recently finding that a haze remains on mirrors that I have cleaned and aluminized, even ones that I have stripped. I am wondering if it might be from the composition of the paper

Re: New washing detergent for mirrors prior to aluminizing
Some people do use nitric acid, but I think it's too scary, and not necessary either. Yes, some places, like Mount Wilson, do use chalk aka calcium carbonate to help with the cleaning. When I switched

Re: New washing detergent for mirrors prior to aluminizing
Calcium carbonate is chalk. Pure alcool can help too. What I want is to obviate the use of nitric acide. ? Bien ¨¤ vous, Charles Rydel ________________________________ To: "VacuumX@..."

Great! Not too many Americans will be able to read them, however. I wonder how much it will cost to order them and have them shipped to the USA. Formidable! (en francais - en anglais ca ne veut rien

Re: New washing detergent for mirrors prior to aluminizing
You need to make sure it's very very very clean before putting it in the bell jar. There are lots of methods used by different people. Some use a slurry of pure calcium carbonate precipitate with

Re: New washing detergent for mirrors prior to aluminizing
It must be rinsed with water. Sometimes I find a haze which must be rubbed off with a much-laundered cotton cloth.

Re: New washing detergent for mirrors prior to aluminizing
Hi, The aime for sure is to do it before aluminize. Is it enough to wash with alconax before and then to alumining or the mirror must be whashed with something else ? ? Bien ¨¤ vous, Charles Rydel
By Charles Rydel <rydel_charles@...> · #3778 ·
Re: New washing detergent for mirrors prior to aluminizing
You use the alconox solution BEFORE aluminizing. Or at least that's what we did. I suspect, but do not know for sure, that if you use it on an already-aluminizers mirror, it might remove the aluminum.
