ABSTRACT:
A saucepan of cast aluminium or moulded ceramics or glass has a trough around its rim to catch liquid boiling over. Small bore ducts lead down within the casting from the base of the trough into the main portion of the pan to return boiled-over liquid. The ducts trap bubbles in the boiling liquid to prevent upward flow. A vented lid may be provided to direct water condensate on its underside to drip into the trough, where it may again vaporize and escape via the vent. A basket can also be fitted within the main portion of the pan.
