Appliances: Free-standindG Cookers
There is a right one for every home, kitchen, style and cuisine culture in the world: free-standing cookers set you free. But enamel is always a must in the most "hot areas": ovens and hobs.
Vitreous enamel makes an important contribution to the cooker industry worldwide. Vitreous enamel, is particularly important in "hot" areas, such as ovens and cooking hobs. Where it combines functionalism and hygiene with unashamed good looks, as it does in other areas.
While built-in cookers are a bit like the password for a modern kitchen - products that have what it takes to play their part in every global or globalised kitchen, free-standing cookers are, as the name implies, more versatile, capable of adapting to any space and – as a result of the variety of colours and sizes they come in – to any type of décor. Which means that they set you free: you will always be able to find the one that is just right, regardless of whether what you need is a refined modern statement, something that reminds you of your grandmother or a rustic delight. Free-standing cookers use all sorts of power sources: some run on gas (natural or cylinder), others on electricity. This makes them also the ideal solution for a house in the countryside and all those areas where natural gas is not piped in. They are also invaluable as second cooker, especially if you are one of the lucky ones who has a room big enough to do some serious cooking and don’t have to worry about space, cooking smells or making a bit of a mess.
A free-standing cooker also leaves you free to move house, because there will always be a place to put it without too many problems. It can even take the different ways of doing things in different regions into account: some types have two ovens (an absolute must if you have a kosher kitchen), others have a grill and/or a huge oven, while others may have a catalytic self-cleaning feature, an easy to clean oven, or a pyrolytic one. These are all features, the convenience of wich experienced chefs will appreciate. Those chefs will tell you food may well be washed and preserved in the same way from one region to another, but there are all sorts of historical, geographical, cultural and religious reasons why we continue to cook and thus to eat our food in profoundly different ways from one area to another. Free-standing cookers also lend themselves better to the needs of communities and catering services, where larger ovens and hobs with both hotplates and gas burners are a necessity.
For reasons that obviously derive from their functions (involving the use of high temperatures, handling foods and acidic substances, the use of detergents…), cookers really put the quality of an enamel to the test. The resulting performance leaves no room for doubt about its superiority to other coating materials: enamel is not damaged by direct flames, does not turn yellow with age and forms no smear marks, not even when subjected to sudden and significant temperature changes; as its surface is vitreous, it is easy to clean, absolutely hygienic, does not chip easily, does not corrode and is not scratched by ordinary kitchenware; charred food remains can be removed with liquid or cream detergents without leaving any scratch marks or damage to the enamel.
In short, there is an ideal free-standing cooker for every region and every style of cuisine in the world, for every type of home, for every room, for every taste. Furthermore for every one of those cookers, adding quality to beauty, there is vitreous enamel.

Resistance to high temperatures
up to 400°C |
Its ability to withstand high temperatures makes vitreous enamel the only cladding material that can be used to line ovens. Direct flames will not damage it, make it turn yellow or leave any burn marks |
UNI-ISO 4530 |
| Resistance to temperature rises |
Enamelled surfaces do not alter in any way when subjected to sudden temperature rises, even when it is significant |
UNI 7232 |
| Easy to clean |
Enamel is very easy to clean. In most cases, a damp sponge is enough to remove traces of dirt. |
NF A 92-032 |
| Hygiene |
Enamel does not allow bacteria to proliferate or fungus and mould to take hold |
