They're several small flaws in the glass including a few air bubbles. It's fine for playing around with but not really sure you want to do anything potentially hazardous or sensitive with it. Too much heat and air bubbles can crack the glass from expanding and that could be bad very bad depending on the nature of use. Be safe just order from someone who has higher standards for quality.
