hard crud in disc rotor

I noticed within one of the air space sections around the outside of the disc brake rotor I had this hard crusty stuff embedded into it somehow: http://i207.photobucket.com/albums/b...1/IMG_1825.jpg
It's kind of like a hard white crusty corrosion and almost concrete-like in hardness but maybe not that hard. I tried to maybe chip it out a little with a hammer and old screwdriver but it didn't really start to chip out very easily. What is this, how do I get it out? thanks

Caked clay from high temperatures? Soak it in kerosine see what happens.

It could very well be concrete that wedged into the gap.

I was thinking of trying to drill out with a masonry bit.

I guess having that one vent clogged could contribute to excess heat buildup on the disc. Not really sure if it would be much of a concern. Yeah I have a Dremel. Maybe Dremel it out if I had the right type of bit I suppose.
Either that or just leave it alone and stop worrying about it.

I would try easier approach first; punch and a hammer.

Not just heat, it's also a balance issue.
