silver nitrate coating?

[nicko0]

i want to dissolve silver nitrate in water and coat glass tubing with it.

i figure inner fire tube is like this

im looking for some direction on what concentration to use

and if i need a binder and if so, recommendations

i have the silver nitrate now. i just want to minimize the amount of trial and error.

is that safe for functional glass? any danger in the silver nitrate coming off from heating?

[nicko0]

it will be melted into the glass just like fume.

think about your silver based colors.

I always wanted to dissolve in Everclear and then dilute it to a non flammable concentration with water. heat up a point a drip a drop or two inside...It may explode! I never tried this...but that is what I would do...

Considering that the main hazard on the silver nitrate wikipedia page is "Explosively reacts with Ethanol" I wouldn't mix it with everclear. It should dissolve into water without any problem. Why add the alcohol at all?

why dissolve in alcohol?

i see what u did there. lulz

it does dissolve fine in water. use distilled water.. that's as far as i've gotten with trial and error, basically.

i think you will want a binder, because putting aqueous silver nitrate onto glass doesn't work well. it goes on blotchy, it doesn't sick or stay even.. it doesn't leave much of a residue like you're probably after. maybe a 200degree blank, and then painted with the stuff would make it evaporate quickly enough to get a smoother consistency... not sure.

i'd like to hear any input about this as well!
thanks

hmmm.

what might be a good binder.

whats that stuff theyre using to stick dichro extract made from?

I used to use 7up to get enamels to bind to float glass in fusing applications.

Put a small dish out, let it go flat and warm and swab it on,let it dry, then apply your silver solution.

I didn't know Silver Nitrate explodes with contact of ethanol. Sorry for the bad info. I saw a video of people who would take a blank point, heat it up in the flame, pop it in a mold and blow (xmas stuff), Then they dipped it into a clear liquid, then another liquid I believe had Silver Nitrate in it. It instantly silvered! There has gotta be a getto way to DIY...I've asked before but never researched it enough to get an answer. Image how much time and product we could all save making silver xmas-Balls, birds, santas, xmas lights, bells!!!

^^ thx so much. i will begin testing in the morning.

I know one of my glass books talks about silver nitrate and may have some useful info... I think its this one
http://www.amazon.com/gp/aw/d/096244040X

I remember reading about it and thinking.." this would be cool"
That's as far as I got with it.

I could be wrong, pm me if I forget to look.
