Hoe does the glass painting proces work? I just finished the third layer with ‘grisaille’. It’s a powder which is paintable when adding water or vinegar and mix them together. When the paint is smooth and liquid I put an evenly layer on the glass and let it dry to become powder again. The next step is to remove parts of it to create texture and shape using different types of pensils and brushes. When it’s finished, I put the glass in the oven at 640 degrees to make sure the grisaille burns into the glass. Now the monster is ready for digital editing. Before I can edit the original, I make a photograph of the glass painting on a led lightbox.
