First glass is heated and then shaped by rotating it in burner flames. There are 4 main types of burners. They are crossfire, fishtail, ribbon and Hand torch burners. Crossfire and fishtail burners are used for slices and angled bends. Ribbon burners are used for curves and sweep bends and hand torch can be used for splices or tapering and tipping of electrodes.

Both Neon and argon gas are inert gasses. If with neon or argon gas a few drops of mercury are added in the tube it will not cause any damage as long as the tube is intact. If the tube is broken it create problem to both environment and health. Due to this reason, many neon shops do not repair neon tubes.

For accuracy sake, all neon signs are manufactured over a fire resistant pattern. Other artistic work can be produced freehand.

Neon sign can be read within 350 feet, even in bright daylight.

Expected life span for a Neon is somewhere between 8 to 15 years. If glass tube is coated it can last for nearly 20,000 hours and if tubes are working on high-powered power supplies, lifespan of tube will reduce.
