It entered Arabic as kahraba, and modern Arabic kahrabā' still means electricity.

What intermediate substance does resin become before it hardens fully into amber?

Sustained heat and pressure from overlying sediment drive off terpenes; most resin never survives, being broken down by sun, rain and microbes.

What is 'ambroid'?

Small pieces once used only for varnish are heated without air and forced through a metal plate under hydraulic pressure.

A 2026 examination of 40 of his pieces found two flies and an ant inside.
