Query: discolored first time I used it!

I bought this from Amazon, and as soon as I got it, I used it to make pasta, I did not have the heat on to high, (I never do) I drained the pasta and when I went to clean it, the bottom of the inside was discolored and splotchy! I returned it to Amazon the next day, and was refunded my money. I'll spend a bit more money and get a All-Clad pot.
