Silvering A Concave Automotive Mirror

[@johnh8205]

your written instructions for tin say 1ml tin to 30ml distilled water. You mixed 1ml to 3oz water. Which is the preferred way to go?

Hello, I understand how it can be confusing. We actually measured out 3 mL of Tin for Silver with 3 oz of water. The wording on the screen and the instructions refer to the ratios. You can scale this up based on how much you would like. You should have 1 mL of Tin for Silver for every 30 mL (which equals 1 ounce) of distilled water. Thanks!

Am I right in assuming any shape object could get an even coating so long as the silver solution is agitated enough (3-5 minutes in the case of the car mirror in the video) to ensure complete covering of the object?

That's a great point. As long as the full surface has sufficient contact with the chemicals then in theory yes. However, with some shapes this could mean that you would need a very large amount of chemicals. This would all depend on the size and shape of the piece.

Alex, How is a 10x magnification mirror made?

[@AngelGildingcom]

Hello, the level of magnification is typically determined by the glass itself, not the silvering. It will also change based on the distance between the viewer and the piece. They would all pretty much silver the same way. Thanks!

@@AngelGildingcom You are right ! for having a 10x mirror the curvature of the concave glass must be 40 diopters and dividing those 40 diopters by 4 you shall obtain ten magnification ! Thanks for your video and the quality of your explanation !

[@javiermancheno8531]

By looking at the curvature of your concave surface (actually your budding convex mirror silvering) I can approximately determine that you already have a 10x magnification mirror (first surface mirror) but since you painted it for protection you end up with a minus (negative image) on the second surface ! In other words you silvered the concave surface in order to obtain a convex mirror ! Thanks for the video one more time !
