Nice video Just a … Nice video Just a tip from part 1 I can see the metal glowing red in daylight this is way!!! too hot when I pour the metal does not glow that bright you can make yourself a pyrometer with a type k thermocouple and a multimeter and excessive stirring of the melt can also cause hydrogen to be dissolved I don’t have stir my metal at all and I have never had a gas problem I don’t even degas I just leave the slag on the metal until right before the pour this helps to protect it .
