Powder coating is the process of applying a dry, powdered paint compound to an object utilizing a low-velocity air powered gun and electrostatic. 

The solid powder particles are electrostatically charged when exiting the low-velocity air powered spray gun. This electrostatic charge attracts paint particles to the work surface and holds them during the high temperature curing process. The end result is a durable, colorful finish that resembles enamel. 

The powder is made of  pigments, specialized resins and fillers that melt and fuse together during the curing process. 

 Powder coat gives you a thick, vibrant coat of color while remaining durable. There are endless possibilities for color choices as well. Colors can range from subtle monochrome to transparent. Some reveal textures that appear once cured. Some even glow in the dark! Another big benefit to powder coating is that you can reclaim the unused powder over and over again until it’s gone. It can be more cost efficient than vitreous enamel. 

Because powder coat doesn't rely on solvents or chemical carriers like traditional wet-paint systems, it’s deemed as environmentally friendly by manufacturers. Although it is seen as environmentally friendly, it’s a fine powder. You should exercise safety by spraying in a well ventilated area and using a face mask. The fumes from the curing process can be dangerous as well.

Yes! in fact, there are many vitreous enameling techniques that can be used with powdercoat. There are many metalsmiths and creatives out there who are pushing the boundaries of the craft. Many, like myself, teach workshops.
