Hi!
I started my smithing/smelting adventure not long ago. I've built a furnace, melt some alluminium, poured it into my clay cast, let it cool down (and used water to make the process faster). Then I wanted to make a sword out of it (as it was just a base stick cast). I heated it up, hit it with a hammer and... it just cracked. Later I discovered that I can even tear my casted metal pieces apart with my bare hands...
Please tell me guys, what am I doing wrong?
