In some tests, solid slag and coal were fed together, while in others the slag was first melted then the coal added afterwards. Coal (at 53% fixed carbon) additions varied between 4, 6, 8, 10, and 12 per cent of the mass of the slag. The mode of addition of the coal, and the reduction periods of the tests were also varied (around 30 minutes).
