11.45 was the last moment when we were allowed to burn chometz.
I was there around 11.30. While putting in fire my paper bags filled with dry dough from all the "chalas" baked during the year, I overheard the conversation between a boy of about 15, and a man in late 30-th.
Boy: Do not throw the foil. It won't burn.
Man: Not true!
Boy: At least, it does not burn here.
Back at home, I took a piece of foil and "burnt" a part of it holding it over the gas flame.
Here are the pics:
The original foil:
"Burned" foil
According to my wife Lucy, the last pic shows the film of Al_{2} O_{3}.
And here are the pictures of the burned phase taken at two magnifications:

What are the conclusions?
