It all starts with the lopin or billet: thin strips of iron and steel called 'alternees' or leaves.

The lopin is heated, hammered, and/or rolled into a rod, stripe, band, blade, iron, or rope – THEY ALL MEAN THE SAME THING and in the finished barrel are described as a 'scroll' by their appearance in Crolle pattern damascus.

The scrolls are larger in 2 Iron/Stripe and (usually) progressively smaller 3 to 4 to 6 Iron.
The size of the scrolls is dependent on how tightly the rods are twisted before being hammer welded into the ribband AND how many alternees are in the rods.

2 and some 3 Iron/Stripe crolle patterns usually have 7 or 8 steel (which stain black) and 7 or 8 iron (which do not stain so silver) alternees or leaves within the scroll.

2 Iron



3 and 4 Iron might have 6 and 6.
