1. Please don't discard the spent chemicals on the ground. Kindy Collect them in a bucket & neutralize the highly alkaline solution with HCl to a PH of @ 7.5 to 8 & pour them in a Suitable drain. 2. You have to use more dilute solutions of Silver nitrate. 3. I have a suggestion. See we have to precipitate the Silver on the glass & not anywhere else. So, first cool the mixture of AgNO3+ NH4OH + NaOH. Dont mix the glucose here. You could then warm the mirror to @ 40-45°C with a hair dryer & first pour a dilute solution of glucose on the mirror. Finally, gradually pour the alkaline Silver-nitrate upon it later. This way I think you can make the silver-deposit on the mirror alone & avoid wasting it.

There is only one thing: please do not just put chemicals into the garden or soil. You do not know what there will grow in future. Everything should be neutralized or be kept in a glas … or am I wrong?

Realistically, the only potential problem that I see here is that a high concentration of silver ions in a piece of soil (compared to normal) is going to kill any bacteria, fungus and many plants. But it doesn't pose a horrible toxicity problem for people or animals. Not the right way to dispose of it, but these are some of the less worrying things to dump.

Terrific to see you slivering the mirror!!! The coating process went on a bit too long. I find even wth the commercial Angel Gilding process, the coating becomes hazy if I try to get a thicker coat. Next time, stop the process a bit earlier. The spray process uses less chemicals too.

If you drag a cotton ball gently over the surface (in the solution) towards the last phase of silver deposit you can prevent the black bloom from sticking to the mirror. Or, stop sooner before it begins to form.

A couple of words of advice, practice your videos before recording, go through the motions without actually adding the chemicals, everything will flow better. secondly, as others have said, please don't just throw your chemical residues on the ground, others have mentioned this too...

@@astrovillager Well, there is no single focal ratio for good spherical mirrors. It depends on their aperture. For a 12 incher, it might be somewhere around F15 which is ofcourse way too big to handle and which is why mirrors are parabolized.

Terrible quality tbh. You will hardly see anything with that coating. And the mirror blank is too thin. You will have shit loads of distortions with this thickness. And yes - if chemicals irritates your skin, surely it will do harm the environment, so no point to "recycle" it under the bench :)
