Leather Cuirass Lorica Musculata, I used to think no way but

[Dan Howard]

It was very interesting to read your experiments. Could you explain further how you hardened your leather with water as there are many people who are under the impression that making it wet renders it useless!.

Leather is hardened with heat, not water. There are two main ways that we think leather was hardened. Water hardening involves soaking the leather in hot (not boiling) water. The other method involves baking it in an oven. Wet leather is definitely useless as armour. But it dries out eventually.
