Note :  If you've mixed different materials in the crucible, and if these materials do not all mix (like if you've thrown an Iron pickaxe, its Wood won't melt with its Iron regardless of the temperature), you'll never see the colored liquid state, whatever temperature the Crucible is, you'll only see the dark gray solid state. That's why you've have to respect recipes as much as possible until you can craft a thermometer.
