Contura Black Hard Anodised Pressure Cooker - CB35

The hard anodised models have all the features and benefits of the Hawkins Contura Pressure Cooker in a hard anodised body and stainless steel lid. The beautiful, durable black finish given by 60 microns thick hard anodising has two benefits. It makes the pressure cooker absorb heat faster, making it more energy-efficient. And the pressure cooker stays looking new for years. Recommended for use on gas stoves. What is Hard Anodising? Hard anodising was first developed by Russian scientists to produce a metal surface tough enough for space travel. The same technology is now used by Hawkins to make its Hard Anodised pressure cookers and cookware. Through a process of electrolysis at sub-zero temperature using a high-intensity electric current, a 60-micron thick layer of aluminium oxide (Al2O3) is formed molecule by molecule as an integral part of the metal. This process produces a surface harder than steel with wonderful properties for cooking. The Hard Anodised surface is non-toxic, non-staining and non-reactive with foods. It is thermal-efficient, heats fast and evenly and is not spoiled by high heat. It is tough and durable, will not tarnish or corrode and will stay looking new for years. Ideal for 4 or 5 persons. Features & Benefits : New improved pressure regulator; Operates at 1 kg/cm2 (15 pounds / square inch) pressure; Pressure-locked Safety lid – cannot be opened while there is pressure inside; Safety valve under lid handlebar for greater safety; Hard anodised body - thermal efficient; heats fast and evenly; Cooks faster - saves more fuel; Will not pit, tarnish or corrode – stays looking new for years; Non-toxic, non-staining – does not react with foods.
