This is great!! I've been trying to silver a mirror using a traditional Tollens reagent process with little success. I can get a thick layer of silver, but it invariably ends up cloudy/milky. I think I am getting crystals growing, making the surface microscopically rough. The quality of the coating here is awesome! I knew about the spray silver process from Googling, but this is the first time I've seen it successfully applied to a telescope mirror. One question I have though : How can I remove a failed silvering attempt? Hydrochloric acid and ferric chloride won't touch it, and nitric acid will harm the substrate (it's not glass). I was about to give up hope, but this video has inspired me to keep going. Thanks.

Really? Very weird. Have you tried using sodium hydroxide then reasonably concentrated ammonia? That might take off the silver too but at the very least it is like to remove any silver oxide that is probably protecting the silver by passivisation.

@MrGoatflakes 4 жыл бұрын

Oh, be careful, adding ammonia to a strong base will release toxic ammonia gas, do this in a fume hood or outside, preferably down wind.

@wayneyoung9612 4 жыл бұрын

@@MrGoatflakes I figured it out. The answer lies in using Tin Chloride to sensitise this surface. I thought I could get away with using another metal-halide salt, but it turns out Tin is the best. Here's an example of the quality of silvering I was able to achieve: flic.kr/p/2i1m92U Note that this is using a traditional pouring technique rather than spraying. Because my substrate is not glass, and is very hydrophobic, getting a spray to wet the surface is tricky. However, sloshing the solutions around on the surface seems to work. Thanks.

Yes ferric chloride. After stripping the mirror, use baking soda to neutralize the glass and any cloth or paper towels. The chemicals can be reclaimed and used a great many times.

@peterpekurar8440 2 жыл бұрын

It's called silver burn where the silver piles up too fast. I've found that diluting the chemicals to half concentration helps, especially during the hot summer months when the chemical reaction speeds up.

If you fail to see a break in the water eg at 3:40, what do you do? Go back to cleaning the mirror? Also there seems to be 2 types of 'water break': 1. Break in the middle of the mirror (spots) 2. Break at the edge of the mirror (never reaches edge) Thank you for sharing these videos.

@peterpekurar8440 3 жыл бұрын

Yes go back to cleaning. The glass should be squeaky clean before tinning.

@peterpekurar8440 2 жыл бұрын

Yes go back to scrubbing. The break you saw showed up in the video but not while I was working the glass. It still worked but better if the glass was cleaner.
