Silvering of telescope mirror | How to make reflector telescope |Step-6| Large12" telescope making 

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?

God bless you my freind, it is the desire to learn that drives our souls.

Thanks for sharing your process with us!

Thanks for making these detailed tutorial.

Great work 👏

Amazing I'm inspired, keep doing the great work... Now I'm curious to know what this beautiful mirror can see!

Old school baby! Very COoL.

Wonderful demonstration, Thanks

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 use full vidoe bro ❤️

Mantap. Sukses terus bro

I recall burnishing the mirror after coating; a chamois and perhaps rouge were used.

thanks from Brazil.

Eu ainda vou fazer o meu. Só preciso da receita desse bolo. Só não gostei de como foi descartado o resíduo.

Very nice video. I enjoyed it very much.

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.

On what surface did you put the chemical to silver it? The concave curve side where you have that sagitta you grinded or the flat side?

Thanks! subbed!

It's like magic

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...

Hello, how can I spray this solution on the work piece? If you answer me, you have helped me a lot.

💝🇧🇩

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.

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

Does it work on glass only? Or I can use it on Plastic, Robber or acrylic too?

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

11:35 это был опасный момент)

Do not discard chemicals in such a manner and background music was not required.

“Do not let the chemical solution touch your skin!” - yet you don’t warn us about dumping hazardous waste right where you just sat-disrespecting the Earth that sustains you and your family. Other than that the process was amazing.

Can i pucrches glass bro

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.

Best part is when you pour the chemicals on the ground, contaminating it. 👍

ATM mentioned that after silvering the silver residues should not be stored because of an explosion hazard.

Ho to aply silver solution mirror frind Or back. Good work❤...my douts please clear

From where did you get curved glass?

Cómo puedo adquirir este producto muchas gracias José Antonio Fuentes

can i apply this technique on fiber-glass or plastic disc?

Can we make it using other meterial than glass..? Please answer anybody..?

Can we use chrom spray paint insted of silvering. SIVER chrome spray paint is not so expensive it cost around ,RS 250 to RS 400 ONLY in onling.

Can you made this mirror for me..?and what price you expect for that ? Pls replay..

ACORDA CRIATURA !!!

Берёт и серебро на землю выливает... оно же денег стоит! ))

Can these chemicals be applied to other than glass?

2:38 May I know the Background Music name?

What is the focal ratio of your 12" mirror?

What about alumanizing?

Зеркало можно было бы и помыть, перед тем как. И неужели чел настолько занят, что сразу два зеркала вынужден делать. Видно же, что он зашивается

This method is for 10% reflecting, Aluminium Coating is 90% reflecting but it expensive

Indo

just mirror or objectif mirror

The result does not seem like I would expect it when done professionally. Please don't put toxic chemicals into the soil!

Bhai ek mistake ho gai Angle

Te-a costat mult kitt - ul?

Could you go a little slower, everything is happening too fast!

How long this coat sustain?

just found out orion sell mirriors so nvm

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.

আপনার সাথে কথা বলতে চাই ভাই! দয়া করে আপনার ফোন নম্বর বা ইমু নম্বর দিন।

Looks like a useless mirror!

Interesante video... pero super aburrido y super antiecologico...
