Abstract The abstract describing the content of the publication or report |
A further assessment of geochemical data previously reported on the composition of Romano-British bloomery slags from the Severn Estuary Levels (16 sites, 113 analyses) reveals that the Na2O/K2O ratio for furnace bottoms from non-tappable bowl furnaces in general is significantly higher than for the tap-slags from tappable devices. As sodium is the more volatile of the two metals, the difference in the ratio could indicate that the smelting process in the tappable furnace, most likely to have been of the shaft variety, was generally of a longer duration and/or at a higher temperature than in the simple bowl furnaces. | ||
