AGA range cookers are made in exactly the same way they always has been. Quite simply, molten iron is poured into moulds. It’s this technique that gives the castings their characteristic surface – each one is unique – and sets the AGA apart from the ubiquitous mass-produced uniformity. While most cookers are spray painted in minutes, the AGA cooker’s multiple protective coats of gleaming vitreous enamel take three days to apply. It’s this enamelling that helps ensure the working life of an AGA cooker is measured not in years but in decades.
