Re: sealing copper...?
What I associate with failure on clears are chalking, yellowing, blistering, peeling, and crackling, caused by weather extremes, sun damage, incompatability, pollution, cleaning etc. Will the salt water soak prove longevity against any of them? Laboratories use sophisticated systems to expose mater...

Re: sealing copper...?
what he said.....erikwinkler wrote:Kelly,
Saltwater is a catalisator for the oxidation process of copper or any other metall.
So if the clear wouldn't hold up outside, you can probably increase your testing speed.
Instead of hanging it up 2 years outside, you can test it for two weeks in salt water.

Re: sealing copper...?
Ismael, 2 weeks to test for reliability is not sufficient. Either you rely personal experience from past work for products standing up to the elements, test for prolonged periods - 6 months or longer - or rely on recommendations from others that absolutely know that it will not fail. 2 weeks under ...

Re: Organic vs Inorganic Reducers Tollens reagent
Ismael, I think you may be misunderstanding the purpose of an MSDS and therefore the interpretation attached to information contained in it.. I am sorry Mr King... :( but I thank you for your answer.. :D I was just asuming the percentage of silver nitrate was 17 percent as stated but I was wrong I ...

Re: Organic vs Inorganic Reducers Tollens reagent
Hi Ismael, You are right that formalin (formaldehyde) and hydrazine both reduce the silver faster than sugar (dextrose, grape sugar, table sugar etc.) and so they are both used for spraying . Mrs King I hope I dont' bother you with my questions Please.... :( I have seen all of the MSDS of your very...

Re: Organic vs Inorganic Reducers Tollens reagent
Hi Ismael, On a related note, you can spray on the silver with ordinary hand-held spray bottles - you do not need to have a dual-nozzle gun and an air compressor. Just be sure that the bottles are all plastic or all stainless steel. Any other metal, such as brass, will seriously interfere with the ...
