While bottom pour furnaces excel when pouring smaller jigs and sinkers their flow rate is limited and insufficient to fill cavities larger than 1-1/2 or 2 ounces. The limited flow rate many times results in wrinkled or incomplete castings. Those larger cavities are better poured with a ladle from a dip out style melter. This allows for a more rapid pour rate that fills the cavity before the lead begins to cool.
