My new glow-wand (glass dab tool) was perfectly straight. I torched the end to take a dab through an oil pipe (mortar and pestle style). After getting the glow-wand to glow, I noticed the end of the glow-wand where the heat was applied start to warp/bend due to the glass softening and gravity. Has anyone else seen this happen? Would particles of glass get inhaled off the glow-wand since it is flexible and soft when heated?
