Pots and Pans

Vitreous enamel for aluminium kitchenware

Today’s pots and pans are practical and attractive: vitreous enamel also makes sure they are elegant and fun – and will last a long time.

For some time now, there has been a change afoot in the music being played in the kitchen for aluminium pots and pans with a vitreous enamel finish. Because there has been a change in what we eat, so a change in how we prepare it. Because we want to use less fats and sauces and also spend less time in the kitchen, both preparing and cooking, because we always have so many other things to do every day of our lives.

Aluminium kitchenware finished with vitreous enamel has enjoyed a new flowering in recent years, because it caters beautifully for all these needs. It is convenient, functional and lightweight, as aluminium is a material that weighs less than others and comes with a guarantee of hygiene; when it has vitreous enamel coating outside and a non-stick one to avoid incrustations and burns inside, you can wash it like a plate – and it is also suitable for all cooking systems: induction, electric hot plates and gas burners. There is a model for every taste and for every regional and international tradition in the kitchen: for cooking spaghetti, steaming, grilling steaks or chicken, making a paella, a cocotte, a crêpe suzette…
Aluminium kitchenware with vitreous enamel coating also has a long lasting tradition of offering an exciting challenge to top kitchenware designers – and the results are there for everyone to see: the format may be small, but this is a field where you can find all the elegance of classical models alongside amusing and ultramodern design statements: unusual geometric outlines, pans with the shape and colours of peppers, fried eggs and ripe or sour apples.

Vitreous enamel works on the outside of the pan to guarantee – as usual – durability, brilliance and hygiene; it also enables the designer to specify all sorts of colours and serigraphy on the sides and the underside: from abstract patterns to recipes that remind you how to make a good coffee or a drink… If you are a manufacturer with the courage and imagination to stand up and be counted, enamel can provide what you need to give free rein to your fancy and your creatives’ verve, or to follow the latest trends in home décor and women’s fashion.
That is why vitreous enamel coated aluminium pots and pans are not just interesting products: they are also ideal for the mass market and entice the buyer with their balanced quality to price ratio.
And there is still plenty of scope for growth and further improvement, both for the non-stick insides and for the outer sides where the vitreous enamel is applied, ready and waiting to tackle every challenge.

Enamel coating – Functional Characteristics
Characteristic Properties References
Resistance to high temperatures Its ability to withstand high temperatures makes vitreous enamel the only cladding material that can be used to line aluminium without any problem: direct flames will not damage vitreous enamel, make it turn yellow or leave any burn marks. ISO 4530
Resistance to temperature excursion Enamelled surfaces do not alter in any way when subjected to sudden temperature excursion, even when it is significant UNI 7232
Cleanability Vitreous enamel can be easily cleaned. Generally a damp sponge is all it takes to wipe away any traces of dirt.  
Hygiene Does not allow bacteria to proliferate or fungus and mould to take hold. Bacteriological survey conducted by the Modena Hospital Institutes

ISO 4531/2
UNI EN 1388/2
Chemical resistance Properties References
Resistance to acids The acids contained in foodstuffs leave no stains or marks EN 14483-1
Resistance to normal detergents Charred food remains can be removed using either liquid or cream detergents, which neither scratch the enamel nor alter it  
Mechanical resistance Properties References
Adherence The enamel cladding must adhere to the aluminium support ISO 13805
