Throw to the side, sometimes called "sidearm" throw.
A properly prepared in advance molotov isn't going to break or open while you throw, but improvised ones are often unsealed and can spill mid-throw.
If you go up and over your back, like a baseball or snowball throw, you risk burning liquids falling onto your back and head.
By swinging over to the side, left or right depending on which hand you throw with, any risk is sent to the side of you. So be careful your don't burn your buddies legs, too.
My forge can melt steel, but I don't like it to. So I don't crank it to full unless I'm using my burners for metal casting.
You want to get steel hot enough to glow, then it's easier to smash into shape with a hammer and anvil. If it melts on you, well the piece is now fucked, especially if you wanted to make something hardenable like a knife.
There's entire sections of metallurgy dedicated to this kind of thing. It's pretty neat.
