Best guess would be it is a gas bubble between the clad layer and underlying copper. But I have never seen one that large. Others may have a different opinion.
Show us the reverse and we will really tell you, but i think Huntsman hit it on the head I like the bubble from the heat ,and it looks like you stuck your finger in it already good try young lad. The fields even look strange and you could see some fire resembalance from the heat. Jazzcoins Joe
