ITO Film on Irregular Surfaces

Am interested in using powder indium-tin oxide in a vehicle to be painted on an irregular glass surface and then fired at around 500 °C to make a conductive film. Would like to know of a convenient vehicle to be used, and also the practicality of firing at 500 °C in air.

Any information on this subject would be helpful.

Thank you.

There is a old method called Spray Pyrolysis that uses tin oxide solution. If sprayed hot and dried it forms a coating. I do not have the recipe but it should be easily available in one of the books on optical coatings and/or solar cells, or some old patents. Would that be easier to work with?
