Pollution performance of silicone coated toughened glass insulators in AC and DC have been demonstrated by Rapid Flashover Strong Layer Pollution Tests either on artificially polluted units or from naturally polluted samples removed from the field.

Most (although not all, see Mott insulator ) insulators have a huge band gap This happens simply because the “valence” band containing the highest power electrons is full, and a large power gap separates this band from the subsequent band above it. There is often some voltage (known as the breakdown voltage ) that offers electrons enough power to be excited into this band.

You’d get a few fancy colors for the reason that some glasshouse did a fancy batch of cranberry glass or created some colored glassware and had some left over so they pressed a couple of insulators with it. Most of the glass houses didn’t make only insulators, they’d make all sorts of glassware That is why you get fancy colors occasionally.
