What is this stuff on my cooking pot?

I just finished washing a pot, and maybe 15 to 20 minutes after waiting for it to dry, I started using it. At the moment I was only boiling water with the top on, but when I came back to the pot, the water had boiled but there was a strange white substance on the sides of the pot above the water. It looked as if someone powdered the sides with flour, however if had no real texture. I tested to see what the substance was by rubbing the side slightly with my finger, but when I brought my finger up to see, nothing was there. Additionally, the part where I put my finger no longer had the substance. If it help to deduce what the substance was, the pot was used to make white rice a few days prior. The substance (to my knowledge) had no taste nor odor. Unfortunately, I did not get any photos as I freaked out a quickly washed the pot (the second time I tried boiling with it, the substance was no longer there).

    Scale from the hard water; mostly calcium carbonate. Harmless, but it can build up and clog appliances that boil water like coffee makers.

    Your tap water must have a high mineral content.

    It's the residue from hard water.

    Look at the inside of your kettle .. where you don't 'wipe it off' every time.

    Either soap scum or hard water residue.
