Support BladeForums! Paid memberships don't see ads! Hello everyone! I am coming to you because I could not find anything online I felt was reliable, and my researching led me to this forum. I am writing a fantasy book and there is a part where they are working to create a new sword out of steel. This is in the early medieval time period (a stretch, I know, but since it's a fantasy story I can get away with it). I know that they would not use water to quench the steel blade (if they are a proper bladesmith) and am wondering about animal fat, but which specifically would be suitable for quenching. This is where my research has failed me on what types of animal fat or oil was used during that time frame. If any might have suggestions or helpful information, I would appreciate that. While this is fantasy, I still want to keep some accuracy in some aspects of my writing to give it some reality. Thank you!
