clean glass. Scour the surface of the glass at least twice with Bon Ami, rinse, then wipe with denatured alcohol.
Linseed oil is the necessary vehicle, it forms a very tough, durable film. Do not use oil paints mulled in safflower oil. Resin mediums improve adhesion and handling on glass, and unlike painting on flexible surfaces (canvas, wood) eventual embrittlement of the paint film is not an issue. It's oftimes advantageous to render using paint near transparent by admixing a varnish medium.
Not being a good comprehensive reader, I'm unclear whether you intend to paint in reverse, on the backside of the glass, so that the viewing side presents the "perfect" glossy surface of the glass pane. I presume so, otherwise there's no advantage to choose such a fragile, breakable support. This requires a lot of fore-planning and "inside out" thinking, since the very darkest passages have to be laid down first, working into the light . . . no room to make overpainted corrections.
