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?
You are right, thanks
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.
God bless you my freind, it is the desire to learn that drives our souls.
Great work 👏
Thanks for sharing your process with us!
Old school baby! Very COoL.
Amazing I'm inspired, keep doing the great work... Now I'm curious to know what this beautiful mirror can see!
Thanks for making these detailed tutorial.
Mantap.
Sukses terus bro
Wonderful demonstration, Thanks
Very use full vidoe bro ❤️
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.
Very nice video. I enjoyed it very much.
Thanks🙏
Hello, how can I spray this solution on the work piece? If you answer me, you have helped me a lot.
It's like magic
I used to have a half can leftover from back in the 70' s but it dried out. I needed to re silver a small 4" adams in the 90's and even all over the world I couldnt get silver nitrate. Here in shreveport there used to be a blackman that remirrored but hes past away i think his name was Mr.Bains. his shop was in allendale
Thanks! subbed!
Most welcome to my channel🙏
Does it work on glass only?
Or I can use it on Plastic, Robber or acrylic too?
I did not experiment with plastic or rubber , may be work but plastic or rubber surface should be very smooth
11:35 это был опасный момент)
Thanks a lot brother i used your video tutorial n watched closely and made 2 old jonga jeep concave mirrors... Please suggest me how to protect the back of the mirror after silvering... What exact paint i should apply to protect the silver or mirror shine and make it scratch proof? I think normal oil paint won't work here or may be chemicals in it can ruine the silver coating itself. What you suggest
You can try with melted wax (candle), but i am not sure , you can try
@@astrovillageri tried spray paint but it damaged the mirror after a week... what paint did you use after silvering it?
Try using red lead oxide paint!!!
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...
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.
Thank you💙 for your suggestion.
Ho to aply silver solution mirror frind Or back. Good work❤...my douts please clear

Thanks for the reply ❤

Yes I got the link
can i apply this technique on fiber-glass or plastic disc?
No
thanks

@@astrovillager what is about metal surface such as aluminum?
@@pichaidvaroonchotikul259aluminium is naturally shine in reflection. It reflects 80 to 92 percent of visible light .
I think you dont need to give extra silvering coat

From where did you get curved glass?
I made it , you can watch my mirror making vedios from first step
Can you made this mirror for me..?and what price you expect for that ? Pls replay..
Sorry, Try yourself my friend.
Can we make it using other meterial than glass..?
Please answer anybody..?
No , my friend.
Thanks!! I should recommend you not to silverise so long time. If you keep glass in silverazing solution long time, silver will cristallise on your mirror face. And you got foggy surface. Get mirror out from silverasing solution right away your mirror begin to shine.
Thank you 🙏
💝🇧🇩
Can i pucrches glass bro
Yes
Your glass surface prepa was not good enough. Degrease with trichorethylene or petrol then Wash with caustic soda then nitric acid pure, then dist water. Ntric will clena your secondary so you can do it again. Perhaps increase the dose of Ag Nitrate too. Thanks for the nice video.
Thank you very much🙏
Cómo puedo adquirir este producto muchas gracias José Antonio Fuentes
English please .i cant understand.
Can these chemicals be applied to other than glass?
May be, I did not try,
@@astrovillager saya juga tertarik membuat cermin teleskop, namus saya ingin membuatnya dari cetakan semen, namun saya masih bingung dengan bagaimana caranya membuat lapisan cerminnya. sampai akhirnya saya menemukan video anda
If you want to make a telescope mirror then glass is only one option . You can't make with other materials.

What about alumanizing?
You can't aluminizing at home and it is also costly .
just mirror or objectif mirror
objective mirror
What is the focal ratio of your 12" mirror?
F/8
@@astrovillager I think you had mentioned in your grinding video that you'll not parabolize it. If you leave it at F8 sphere, the Peak to Valley wavefront error will be about 1/2 waves which is less than Rayleigh's minimum standard of 1/4 waves!
@@biswa145 thanks, i am new in mirror making. But i kew over f/8 spherical is ok, so what should be the f ratio of spherical mirror?
@@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.
BTW I'm also new to mirror making. I have just completed my 6 inch f7.4 mirror. Next planning to work on a 8 inch! It's great to watch people like you sharing your experience through videos. Keep it up! 👍

ATM mentioned that after silvering the silver residues should not be stored because of an explosion hazard.
How long this coat sustain?
6 months at good condition, but after 6 months yet you can use, little bit brounish colour appear. Again you have to silvering it . silvering chemicals are not so expensive .

This method is for 10% reflecting, Aluminium Coating is 90% reflecting but it expensive
Only 10%?? No, I think it around 60%
@@astrovillagerbro, You should find Aluminium coating method
Actually silver is the best metal with 95% on the visible , is mirror is far from perfect generally a primer solution of copper is used to help silver to hold on the mirror and reduce the nitrate to pure silver
@@brunobastos5533 💯💯
Best part is when you pour the chemicals on the ground, contaminating it. 👍
just found out orion sell mirriors so nvm
The result does not seem like I would expect it when done professionally. Please don't put toxic chemicals into the soil!
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 :)
Will it be easier to buy a new one its cheaper and environmental friendly 😅. Thanks for the effort.

Looks like a meth lab 😂😂😂😂
Плохое серебрение. Неаккуратно, покрытие низкого качества. Да еще и раствор просто на землю слил. А там серебро.
Thanks🙏
а шо с ним делать правильно?
Interesante video... pero super aburrido y super antiecologico...
Looks like a useless mirror!
