Linothorax vs Quilted linen vs spolas

[John Conyard]

Paul B. was indeed the first to propose tawed leather for armour.

But I doubt tawed leather was used as armour. I suspect, but can't prove that vegetable tanned leather was more popular than tawed leather in Athens. Generally in Europe it was. And alum can be used, as already discussed, to help tan leather. This may have been the process used in Egypt to make armour. Not tawing.

Tanning and tawing are different processes. And alum can be used in both.

So for example alum could be used to produce white vegetable tanned shoes. Vegetable tanned leather shoes are used throughout history. Tawed leather be definition will rot in water and does not seem ideal for shoes. They may need tanned leather soles.

Logical, yes?
