FIRING (8) Methods en pottery.
Firing methods: A kiln can be heated by burning wood, coal, gas, or electricity. When coal and wood are used as fuels, they can introduce smoke, soot and ash into the kiln which can affect the appearance of the ware. Modern kilns powered by gas or electricity are cleaner and more easily controlled than older wood- or coal-fired kilns and often allow shorter firing times to be used.
