Our borosilicate glass tubing has snap cut ends, meaning the edges can be very sharp and uneven. The glass tubing is basically scored with a file and then 'snapped' between the thumb and forefinger leaving an edge that is rough.

Fire polishing is when the ends of the glass tubing are heated to create a smooth rounded finish that is not sharp at all.
