There are ways, I've tried some but have not been successful. Score and snap only works for glass sheet or small diameter tube. Most methods seem to involve scoring and applying a large amount of heat so it expands and cracks along the score. There are some YouTube videos of various methods. Let us know how you go. Just make sure you play it safe with whatever you try.
Also, I've bought a couple of cheap cutting wheels (one from the big green shed, another from a Chinese website) and they were both rubbish. I found a cheap router bit (that I had no intention of ever using) did a better job of scoring borosilicate glass.
