Hello,
i have some questions about glass silvering;
i found this procedure:
1) make a solution (A) with 1.4 gr silver nitrate + 17gr water
then, add to the solution 1.2gr of ammonia 26% solution
2) make a solution (B) with 9.2 gr potassium bitartrate + 4gr sodium carbonate + 17gr water
3) make a solution (C) made of 5gr (A) + 5gr (B) + 100gr water
4) put a very clean glass sheet (*) in solution (C) , and leave it in the solution until the glass silvering is done.
(*) the glass must be very clean before silvering :
to clean it, wash it with a 6% tin chloride solution,
then rinse it with hot water.
The author claims that with this procedure is possible to silver also plastic with very smooth surfaces.
The questions are:
1) Do you think that this procedure can really work also for plastics?
2) How can i make the plastic surface clean (and smooth)?
do you think that the 6% tin chloride solution is suitable also for plastics, or does need another cleaner?
I am interested in plastics such as PLA,ABS,PETG; i have read somewhere that PETG is more suitable than the others...
P.S: this is my first post in this forum,
i am sorry if i have posted the question in a wrong forum section, in this case i ask to moderator to move it in the right place...
Thank you!

how to turn glass into a mirror

yes it is needed to sensitize the plastic
i read in other place that the tin chloride solution (after cleaning with alcool) has function of 'sensitizer'
somewhere i found that the object must be plunged in a concentrated (5%) tin solution for about 30sec, in others i found it must be kept immersed for 30minutes in a very less concentrated (0.003M) solution...
by the way...do you know how to make a stannous chloride solution?
thanks!
