I am using Rutland black furnace cement thinned with water to clay a blade. I will be using a few thin coats instead of a single thick coat. First attempt at claying. Can anyone suggest (approximately) how thick to apply it. I know I may have to experiment a little, but I'd like to have an idea where to start, I am interested in differential hardening, making a hamon is not an issue.
