The metal has just been poured into the mould. It went in fine, and I stopped pouring once the sprue pin has filled up. But then, the sprue pin started bubbling. Hmm, that’s not a good sign. Presumably the sand was too wet. :-(
I poured the rest of the metal into the sand tray, making an impractically large ingot. Wow, I really did melt way more metal than I needed. However, it would’ve been much more annoying to have melted too little.
Surely the casting will have been ruined by the escaping steam?
Ian and I left everything to cool, and retired to my flat for a cup of tea.
