That was no doubt light-matter, a non-metal, and as such, non-conductive to light.
2
This light-non-metal did the same sort of thing; it reflected light and passed electricity.
3
Like sulphur, an electric non-metal, it reflected the base of which it was formed.
4
It occurred to Mara that perhaps it was enamelled, or consisted of some sort of non-metal layering.
5
Composite is a non-metal, graphite-like substance.
1
At the same time, other high-stretchable nonmetal materials such as conductive polymers generally have a limitation of low electroconductivity, restricting their further applications.
2
It's been a while since my nonmetal days, and I've kind of forgotten how this goes, but I bet I can figure it out.
3
Hoping that the nonmetal handle would interrupt a lethal electrical shock, in seconds I was hacking at the conduit like a demented ax murderer.
