Important Things to Note about Aluminium Cookware:
1. Some dulling or darkening of the interior will occur with use. This is normal oxidisation. 
2. Aluminium is not dishwasher safe. Please wash by hand in hot water using a detergent of choice. 
3. Where-as it is perfectly safe to cook acidic foods in aluminium pots and pans please do not store acidic foods in them. The acid may cause pitting of the aluminium and result in the food tasting slightly metallic. 

NB: It may hurt the pot but it won’t hurt you.

In 1920, Italo Ottinetti, born in 1898 and veteran of the Great War, together with some partners, established in Baveno, the typical village on Lake Maggiore currently in the province of Verbania, the metallurgical company that is still named after him. In the small factory, aluminium was full processed: the bar was melted to obtain the plate that in turn was rolled to obtain the disk from which, after pressing or turning, the finished product was obtained. 

A purely craftmade production of high quality articles that Italo Ottinetti sold personally, travelling all over Italy as far as Sicily. At that time, the range included cutlery, pots and pans and household accessories, as documented by the catalogue of 1925, year in which Italo Ottinetti became the single owner of the company.
