Bottom pour would be my very last choice if there were no other pots made. The spout will drizzle the melt and your ingots will look like hell. What you want is a Rowell ladle that drops 2-3 lbs of melt and any cheap cast iron pot off eBay. Making the ingots goes quick and the ingots will be smooth & even on the topLooking at a bottom pour ladle for making bulk ingots.5-10 pounds.
