Abstract: A smoothing iron has a body structure with a handle (5) and a baseplate (36), a gas burner (44), for heating the baseplate (36), and a tank (8) to contain gas, for fuelling the burner (44), maintained under pressure in liquid form, for example liquefied butane or propane gas. In a preferred form, the body structure has a first portion (1) with the handle (5) and tank (8), and a second portion (2) with the baseplate (36), those portions being air-spaced with the exception of connections (4) of very low heat-conductive capacity. The handle (5) and tank (8) are advantageously integrally moulded of plastics material.
