um. Maybe we're getting the coke oven and normal furnaces confused?

Coal in a coke oven eventually makes creosote oil, but it's very slow, wheras you can burn charcoal (and maybe coal as well? which version, exactly?) in a regular (or electric) furnace to get pure creosote oil more quickly. to quote...something..."some servers disable this".
