Huzzah! success! This just goes to show, if you take a 3D printed scan of an ancient bronze spear head, cast it in the wrong bronze alloy (aluminum bronze vs. tin bronze), and pour into the wrong casting medium (petrobond sand vs. stone molds), you're gonna have a bad day. Also, anything is possible. With enough ingenuity and sheer stubbornness, you can make stuff despite problems.

This is the second attempt at sand casting this spear head. The first attempt is at    • Casting an Aluminum Bronze Spearhead,...  
In that video, I talk much more about bronze age casting and this particular spear point. If you were expecting rambling about the spear itself and about "bronze age" and what that means, watch that video. This video is the successful bronze casting.

If you want to hear much more rambling about aluminum bronze as a specific alloy, watch this:    • The Bronze Alloy as Tough as Steel! (...  
In that video, i make the aluminum bronze from scrap copper and extruded aluminum
