Although molten iron didn't flow from the furnace into a bed of "pigs" as was done countless times at Long Pond, enough ore was smelted to require the furnace tap hole to be opened to allow slag to flow out.

Historically, the Long Pond furnaces were "tapped" twice a day.

Slag is a by-product of iron production, made of impurities found in the ore.
