Maybe it's from when you fill it and all you need to do is to wipe it off with a wash cloth? If you have a pin hole leak, I'm betting that as you use it, the Calcium will eventually plug it up. I remember Grandma's old kettle; she put a marble in it to keep it from bumping and it gathered up a lot of the calcium and grew quite large. A good "bump" could possible poop a little water out the spout too.
I would wager that the marble that Grandma used was made of actual marble.
I tried that 'trick' with a cast-iron kettle on my wood heater... the glass marble that I used eventually shattered. Antique shops may be a source for an actual 'marble' made of marble.
