If you're making a stained glass lamp, a quality heat cap is a must.  This 4" brass heat cap can transform an ordinary vase into a masterpiece reminiscent of Louis Tiffany's original stained glass lamps.  This is no small task obviously, but if you are ambitious and patient, you can do this.  You have to believe in your self and pace yourself with stained glass work.  Don't rush things, slow and steady wins the race.  If you get frustrated, take a break, take a breather, step outside.  This is not a race.  Quality is attained with patience and determination as well as a large amount of practice.  Probably not a project for a beginner, you may want to start with something less intense for your first project, but if you are set on doing a stained glass brass lamp, this is your cap!
