Jeri reproduces the Terra Labs transparent conductive glass experiments with stannous chloride. The stannous chloride decomposes to tin oxide on the glass when heated.

  • Please see this video how to make the SnO2 layer even more better and more

  • @overunitydotcom Very nice results!

  • I am getting only white smoke and very heavy white coating on glass to the extent the transparency of the glass is compromised and there is no rainbow color and there is no electric conductivity. Any idea where I may have made a mistake.

  • @jucest The glass needs to be very hot. My attempts to do this by heating the stannous chloride with a torch were not great, but I get better results in a kiln. Maybe you can try heating the glass more.

  • why do we need stannous chloride here?

  • @chouabali The tin oxide conductive layer comes from the decomposition of the stannous chloride.

  • Wonderful work. I wish to put action steps in writing. So they can understand more

  • Would the decomposition of stannous chloride liberate chlorine?

  • @daviddanielgraham Stannous Chloride has a melting point of 370 C and Boroscilate has a melting temp of 800-ish C... Soda - ash glass has an even higher melting point temp. Is the point here just to form the tin oxide layer on the surface?

  • Has anyone tried this technique on Boroscilate? 

  • whre do you heat the glass with stannous chloride?... ty for your reply

  • I thought oxide WASN'T conductive?

  • I found where you can buy Stannour Chloride

    You can buy Stannous Chloride Powder at the following site.

    StannousChloridePowder com

  • If you were to immerse the glass in pure oxygen gas and then heat it up it may improve the decomposition of the Tin chloride. Cool thanks I am going make some tin chloride now
