Hi there, I am looking to create a mirror surface on a glass tube (0.5" diameter, 6" long) for a photography experiment. Where can I obtain the chemicals you mention?

This reaction is well known to organic chemists as Fehling's test for aldehydes. It can also be used to produce first surface silvered mirrors. But if I just wanted a silver glass jar, I would go for the much cheaper option of spraying the inside with bright chrome paint. And PLEASE delete the 11 photos of the same bloody jar !

Ooops ! My memory has slipped up again, that should have been Tollen's test, not Fehling's.

What is the point of this?

If you see all the steps, it's how to add a coating of silver to the bottle.

Yes, I see that, but why?

Why not?

The last step states, "Re close your jar or glass soda bottle and NEVER open it!"

So again, what is the point in coating a vessel that will never be opened. I can accomplish the same effect by filling it up with paint.

All I'm asking for is a simple introductory statement by the author.

Not every project requires a practical, reasoned explanation. Sometimes you just Make.

If you can't see the point of using chemistry to make a perfect mirror finish, just because you can, then I doubt anything the author says will change your mind either.

You win.

I didn't realise it was a contest?

Silver nitrate isn't exactly cheap and I suspect you're flushing most of it down the sink which isn't a good thing. Also, if you varnish the inside you can open the jar as as often as you like without the silver turning black through oxidation.

Really needs an introduction to let readers know what you're doing. I didn't know till step 9... needs more pix, not just the same one over & over. But it is an interesting subject !!

This is how they used to add the silver layer to mirrors.

You really ought to do the experiment again, and take a photo of each step, or even take a video.

Agree, would be helpful to visually see the process.
