Nice looking sword and story. The metal seems to be a standard bronze except for magic dust ashes.. I do not know what the addition of mercury would do as it would vaporize.
An interesting point Tim. I have read the text in the link and wondered similar things. Melting points for the metals are vastly higher than that of Mercury but would it actually vaporize? Perhaps metallurgists here can offer some insight to the subject about how metals meld?
