gloves seem like they would only be an impediment to tactile feedback and to the fine motor skills Robert mentioned. that said there is a Korean bender who wears a glove on one hand, leaving his other (dominant?) hand free for manipulation of the glass. (unfortunately, i dont know his name because i do not read/speak Korean)
personally, as a novice bender, learning to bend is difficult enough without a 50% handicap due to a bulky glove, but to each their own.
Robert, here is a video of the one-gloved Korean bender in action, and there are many more on his YouTube channel. i suspect you may also find the segment starting at 09:23 of this video of particular interest; as he demonstrates making his own electrodes.
Please note: as a disclaimer to newer/novice/learning members: there are many questionable practices shown in this & other videos on that channel. some are safety-related, others are quality-control related. sure he makes functional neon, but i urge you to strive for the safest & best neon possible. some of the questionable activies that i saw (in this and/or other videos) that should be avoided:
1) touching the manifold while bombarding (he opens & closes the main stopcock multiple times)
2) not using mercury traps; putting a ball of mercury directly into the (8mm?) side tubulation and pumping around it. seems to me that would be an easy way to suck mercury into your vacuum pump.
3) dirty mercury syringe lying around in an open dish in a puddle of dusty mercury (contain your mercury for safety AND to keep it clean)
4) using latex tubes anywhere on your vacuum manifold. latex is leaky and never stops outgassing.
5) using heat shrink tubing for high-voltage connections... GTO splicing, substitute for electrode boots, etc. Heat shrink tubing is not rated for the multiple kilovolts that are required to power neon signs. (apparently that's fine in Korea?)
those objections aside, however, i do enjoy watching how neon is made all around the world. this particular video also shows phosphor coating of tubes, which is not commonly done in the US, so that is neat to watch.
