A few more photos - it has cleaned up quite nicely and with interesting rose tint to the blade and I’m wondering if anyone can educate me on the chemistry of the steel composition used for keris forging. I am very interested in blacksmithing but am ignorant of what the makeup of these blades might be and what would influence the colour - i.e. might it have a bit of copper in the mix or would a high phosphorous content possibly contribute to the tint?
