Hi all.
I am facepalming right now.
Figured out why my conducting glass never worked.
When making conducting glass...
The sheet you want to coat needs to be at approx 400C, and also it must be set up so that the stannous chloride is at one end on the SAME SHEET OF GLASS.. -------------------------- i.e. SnCl --------*-*-*-*-*-*-*-*-*- * = tin oxide Hot Plate applied
The sheet which gets hottest is where the tin oxide will end up. This explains why I have had precisely zero success with the experiments(s).
Also means that potentially my broken pieces of glass may yet be useful. Line up the cracked piece with the tin chloride, so another sheet is next to it. As long as the gap between them is filled i.e. with fire cement all should be well.
Induction heating may work, however the metal sheet needs to be a thick piece.
I would tend to use a flat iron plate the same size as the sheet of glass.
Also advisable:- put a piece of heatproof cloth between the glass and the heater plate. This allows it to cool slower, reducing the chances of the glass fracturing.
Drop some glass wool over the apparatus to prevent glass fracturing.
Turns out that I had (wrongly) thought that the tin oxide ended up on the top piece of glass. Well, duh.
Feel free to laugh at my misfortune if you wish, I am now going to try again with a piece of flat iron plate, salvaged induction cooker and glass.
On the flip side, adding indium metal to the SnCl would probably make ITO, which would be handy.

Hi. First post here...
I have multiple times made tin oxide coatings onto microscope slides with this kind of setup: g------g g = broken window glass piece (about 8 millimeters thick) *-------g * = tin chloride (solid) *-------g - = the microscope slide (the window glass and tin chloride are atop the slide) g------g Another microscope slide is then placed atop the window glass pieces. The microscope slide is on a metal plate and the metal plate is heated on the hot plate. You also will need to blow the white tin oxide fumes between the two glasses (maybe with very low rpm pc fan).
I have noticed that the thickness of the window glass pieces and the temperature of the glass effect the conductivity of coating. The best conductivity is on the coating that have kind of a rainbow colors to them(this means that there is thin film on the glass).
Best conductivity that i have measured was above 2 kohm no matter how close i placed the multimeter probes. To get more conductive coatings the tin oxide will have to be doped with indium or fluorine.

OK, thanks for that.
I have started a new job so am not going to be online much, so in the meantime PM me if you need any equipment or components as I need to make £500 by the 23rd September somehow.
