A drawing/ print is selected. The paper is placed underneath a slab of clear (and clean) float glass. The glass should not move throughout the process, so it is often taped down onto the drawing. A bridge (wooden device) is placed over the drawing, as to prevent your sleeves or arms to come into contact with the drawing while you're busy painting.

A pigment is then prepared by mixing together grisaille, a small amount of gomme argentique and vinegar. You should obtain a grey, thick and grainy fluid paste. This paste is then applied onto the glass with long thin sable brushes, to trace the drawing. Once the first layer or outline is traced, you place the painted glass into the oven to bake. When it has finished baking, the grisaille can no longer come off the glass. The next layer is prepared.

Next we apply a layer of silverstain with mineral water. Silverstain looks like a thick, clay-like mixture when applied on glass. After the silverstain has baked and dried in the oven, we will see how it transforms to a shady yellow texture when the excess has been washed off.
