Interesting Ibrahiim, thanks for the description. Would be interesting to see a video of the process.

Every time one is fired somebody makes lots of money.

Ibrahiim -Yes, that tell-tale dot is right in the centre of a flower amidst the four bosses. Probably spun over a hard wood dome shape. The figures appear to have been engraved, that is, cut with a small chisel. Either pushed by hand or with a small graver's hammer.

Ian - this shield weighs 3 pounds 4-1/2 ounces (1488 grams to you). My tulwar, posted Oct 1, weighs 2 pounds 3 ounces (992 gram). I have no knowledge of what constitutes an acceptable shield weight for combat.

Tim - Thanks for the video. In my employed days I saw a lot of half-doughnut shapes, about 610 mm OD, 3mm wall spun from nickel heat resistant alloys. They were for gas fired heat treat furnaces, an environment which tends to make Hastelloy X disappear. The aerospace guys have used X since the 1950's.

Salaams I think the give away sign of a spun decorated item is in its repeat pattern which because of the fast turning of the work and being rammed by a spinning die is cut in seconds requiring only finishing hand work by the artesan..by chisel and mallet . The bulk of the pattern is done by this rudimentary lathe. The centre dot is there because that is the method by which the item is secured so it does not move when spun ramming is taking place. This is the ancient technique of spun decoration; not the same thing as modern lathe spinning. Sometimes you see two dots at the centre where it has slipped giving a double strike rather blurred pattern ... I assume the work is flat but later in the case of a shield or bowl the item is hand worked to shape.

The famous book by Rachel Ward on Islamic Metalwork refers.
