Coke Quotes (3 quotes)
I was fascinated by fractional distillation as a method while still a school-boy, and built in the cellar of my home, which was my combined workshop and laboratory, distillation columns, packed with coke of graded size, some five feet in height. They were made from coffee tins (obtained from the kitchen), with the bottoms removed and soldered together! Experience with them served me in good stead and by the time I graduated I had a good understanding of the problems of fractional distillation.
July 11, 1656. Came home by Greenwich ferry, where I saw Sir J. Winters project of charring sea-coal to burn out the sulphur and render it sweet [coke]. He did it by burning the coals in such earthen pots as the glassmen melt their metal, so firing them without consuming them, using a bar of iron in each crucible, or pot, which bar has a hook at one end, that so the coals being melted in a furnace with other crude sea-coals under them, may be drawn out of the pots sticking to the iron, whence they are beaten off in great half-exhausted cinders, which being rekindled make a clear pleasant chamber-fire deprived of their sulphur and arsenic malignity. What success it may have, time will discover.
