Clearly, some of you don't have the sense you were born with.

Hi,

I´ve burned myself 3 times, two of them in the fingers from grabbing hot rods, I´m used to leave them with the hot part heading the wall but these times I was distracted and left them heading towards me so there´s was no way I couldn´t miss tha! hahhaa!
And the third was in my forearm, I hit it againts the head of my Cheetah, luckily it was not turned on at the moment, I had just finished torching that day.

I'd like to apologize all those times I laughed at you guys for sticking hot rods in your mouth. I'll be breaking THAT habit pronto.

shocking.
Actually the waving is done for a different reason and works quite well at preventing shock. When you remove the rod (rapidly) from the flame the heat does not stop. The heat on the surface of the glass now has some time to travel inward while the hot outer surface cools some. Basically what you are trying to avoid is having a very hot molten outside and a very cool inner core. The difference in expansion will tear apart the rod resulting in the "shocky" glass.

Shock can also be caused by other reasons (mixed colors such as pink, scratches, non amorphous structure, chemical composition etc) which is why some glass is more prone to shock than others.

Yes, there are other ways to avoid shock, preheat, heat slower, heat indirectly, heat with rotation, or heat with waving. All are valid methods that try to accomplish similar tasks... bring up the core temperature before the outer gets too hot.

Some of those thumbs look like mine - too bad my pics are on the laptop that died.
you should see the "bite club" at a reptile forum I used to hang at.
