Glass Mug

I bought a curved clear glass tea mug for a dollar at Job Lot as consolation while waiting to get paid from a client. I love this mug because when I fill it with cold tea it is cloudy until the tea heats up and then becomes clear. Then I add milk and it forms clouds and I drink it and then the glass is cloudy from use. Then I wash it and it's clear again. So much entertainment from a simple tea mug.
