Conductive Coating for Glass
I am attempting to make an etched 6" diameter float glass conductive for electroforming. I have tried ~600 Angstrom thick evaporated gold: too inert and some tends to stay with the form and some with the mandrel. Chrome coating tends to stain in the nickel sulfumate bath. Aluminum coating is also prone to staining and must go in 'live'. Any suggestions?
Thank you in advance.S. Scott

The other way to make the glass conductive is to use silver, copper or electroless nickel. The silver is usually a paste that you apply to the glass and back or you can immersion Ag coat. Copper and or nickel can be applied by electroless means. There are a number of suppliers of these technologies out there.

Hi, JD. I've never heard of "sm02". Is this some brand name product or was it a typo and you meant tin oxide? If you can reference where you saw this formula, or what kind of glass it was used on, and for what purpose your glass needs to be made conductive, and why S. Scott's and George Shahin's answers were inappropriate to your needs, maybe someone can help. Good luck.
