The art of reverse painting began in china centuries ago. Using a specially designed brush with a curved handle and sometimes only one bristle, the skilled artisan carefully draws the outline of the design on the inside of the mouth-blown glass shape. Next, the foreground details are painted (eyes, cheeks,lips, etc.) continuiong with each additional layer of colour in reverse order, the background being the last application. Skill, patience and careful planing create a work of art to be treasured forever.
