How does a cupola tender observe a furnace?
The cupola tender observes the furnace through the sight glass or peep sight in the tuyeres. Slag will rise to the top of the pool of iron being formed. A slag hole, located higher up on the cylinder of the furnace, and usually to the rear or side of the tap hole, is opened to let the slag flow out. The viscosity is low (with proper fluxing) and the red hot molten slag will flow easily. Sometimes the slag which runs out the slag hole is collected in a small cup shaped tool, allowed to cool and harden. It is fractured and visually examined. With acid refractory lined cupolas a greenish colored slag means the fluxing is proper and adequate. In basic refractory lined cupolas the slag is brown.

Cupola furnaces were built in China as early as the Warring States period (403–221 BC), although Donald Wagner writes that some iron ore melted in the blast furnace may have been cast directly into molds. During the Han Dynasty (202 BC – 220 AD), most, if not all, iron smelted in the blast furnace was remelted in a cupola furnace; it was designed so that a cold blast injected at the bottom traveled through tuyere pipes across the top where the charge (i.e. of charcoal and scrap or pig iron) was dumped, the air becoming a hot blast before reaching the bottom of the furnace where the iron was melted and then drained into appropriate molds for casting. A modern cupola furnace was made by French scientist and entomologist René-Antoine Ferchault de Réaumur around 1720.
