"Pyrex"

[zoiDman]

There is no need to anneal glass twice over.. Once it's annealed it's annealed. Annealing a second time will do nothing, If you want to add to something though youd have to re heat it to work it and then re-anneal it (I have work in and out of the kiln constantly). Boro can be annealed an infinite amount of times. Pyrex has become the generic term for borosilicate glass even though Pyrex cookware is no longer made from borosilicate.. The whole thing is pretty misleading.

My wording was Pour. Perhaps I should have said Two Heat Treatments.

But I agree, Pyrex has become a Mis-Leading Term.

Hey guys, I am a glass artist out of Pennsylvania specializing in very intricate glass pendants and marbles. Since I've seen this word "Pyrex" tossed around so much in the ecig community, I would like to inform people what it really means. The term "Pyrex" has become a term for any type of Borosilicate glass and it seems to be used very loosely in this community. Now I'm sure everyone has heard of the company Pyrex.. well if you go to their site you will see that the word "Pyrex" has a copyright type symbol next to it.. I notice that none of the websites I have gone to that sell glass tanks include that emblem (yet they ALL say Pyrex glass) . This leads me to believe that their Borosilicate is not actually made by the company "Pyrex" but is just being considered "Pyrex glass". This can be extremely misleading to the untrained eye. Borosilicate glass can either come from China or elsewhere (USA, Czech Republic ext.) and the difference is quite significant. The companies that make clear borosilicate are Schott, Simax, Pyrex, and glass from china is just referred to as "China glass". The companies you see selling colored glass tanks (amber, violet, cobalt ext.) are at the very least using china glass for their colored tanks. I am not here to point fingers, just to inform the community what they're purchasing because the retailers are not doing too well of a job of doing so.
P.S. PLEASE do not buy any tanks that don't say they have been annealed IF THEY HAVE BEEN WORKED IN A FLAME, they are literally time bombs just waiting to break at any moment and could break for no reason just sitting on your desk dormant because they still have stress in them from being flame polished.. I am working on releasing my own Boro carto tank using Simax tubing at Vapefest this year if all goes well, it will be my first time attending a vape show! . Ive attached a few images of my recent work. I hope some of this was informative!!

Edit: I shouldn't say don't purchase tanks that haven't been annealed but please purchase them at your own risk.. I feel it fairly essential to anneal any piece of glass.

Those are really beautiful pieces. I have a friend who collect art glass marbles. I turned a number of exotic wood stands for some of his pieces.

On the subject of the Pyrex name. It's the same with Kanthal. Kanthal is a brand of heating wire.

Great video fourtytwo! That's very interesting about Kanthal also! I haven't dipped into the rebuildable world yet, I don't know that I'll have the time for it lol, these carto tanks on top of making pendants and marbles will certainly take up most of my days for now atleast. Im excited to try to get out to Vegas for Vapefest. Really look forward to meeting people in this community!
