A glass writing surface behaves nothing like melamine. Ordinary dry-erase ink is formulated to key into a slight texture and on glass it gathers and looks thin. Liquid chalk markers lay opaque pigment that reads strongly against whatever is behind the panel. They need a damp cloth rather than a dry eraser. See whiteboard markers, whiteboards and whiteboard accessories.
