What is Bakelite and what was it used for?
Bakelite, or polyoxybenzylmethylenglycolanhydride, is an early plastic that was quite sturdy and could withstand high temperatures. It is a thermosetting phenol formaldehyde resin, formed from an elimination reaction of phenol with formaldehyde, usually with a wood flour filler. It was developed in 1907-1909 by Belgian chemist Dr. Leo Baekeland. The black plastic handles and knobs on your Grandmother's old pots and pans are made from bakelite. The outer plastic shell of any rotary phone you may have seen was made from bakelite. Bowling balls, the old black ones, were also once made from bakelite too.
How can you make Bakelite into a conductor of electricity?
Clean and dry Bakelite is a such a good insulator it would not be possible to use it to make a conductor of electricity. However if the piece of Bakelite was sprayed with water all over and a high enough voltage was applied to it, the water (not the Bakelite) would conduct electricity. Another possible answer is that if the Bakelite was made as thin as, say, some cigarette paper, and if a very high…

In 1862 the first man made plastic was made by Alexander Parkes for the Great International Exhibition in London. It was an organic material from cellulose and once heated could be molded, but retained its shape when cooled. The problem with it was the high cost of the raw materials needed for production. During the latter part of the 19 century people wanted to find a replacement material for the ivory used in billiard balls…
