I accidentally put my macchinetta on the stove with no water in it. A few minutes have passed until I realized what I have done, and in the mean time the pot has overheated, started to smell quite badly, and it's bottom has received a (permanent?) brownish hue.
The pot is stainless steel (bialetti venus model), but I don't know what the inner coating is made of. In terms of toxicity, is it safe to continue using it?
