'''Shingling''' was a stage in the production of [bar iron](/source/wrought_iron) or [steel](/source/steel), in the [finery](/source/finery_forge) and [puddling](/source/puddling_furnace) processes.  As with many ironmaking terms, this is derived from the French - ''cinglage''.

The product of the finery was a [bloom](/source/Iron_bloom) or loop (from [old Frankish](/source/old_Frankish) ''luppa'' or '' lopp'', meaning a shapeless mass); that of the puddling furnace was a puddled ball.  In each case, this needed to be consolidated by hammering it into a more regular shape.  This was done manually with heavy hammers; later by a [waterwheel](/source/waterwheel) or steam powered hammers, leading to modern [power hammer](/source/power_hammer)s.  The result was an oblong-shaped iron product similar in appearance to shingles used on roofs. In the finery, this was part of the work of the finer; during puddling, it was done by a special workman called the shingler.  The iron (or steel) then had to be further shaped (drawn out) under the hammer or rolled in a [rolling mill](/source/rolling_mill) to produce a bar. In more recent times, the process was carried out using mechanical jaws to squeeze the puddled ball into shape.
