Thanks for all the suggestions guys, it is very much appreciated.
So quick update...
Re: Quartz - At first glance, quartz seems like the solution but quartz is about 7x more expensive than glass and infinitely harder to work with. Due to our design requirements, using quartz isn't a feasible option today as it is harder to bend and work than glass. Until it makes more economic sense, quartz isn't the right path.... at least for now.
What has been working great is Stinkmeaner's suggestion of spreading the heat around more as well as using a smaller flame. I vaped about 20 bowls before the initial one cracked when I used full torch power and was heating pretty much one spot. I am at about 30 bowls with the current model and so far so good.
@stinkmeaner - that copper concept is very interesting, I will def do some experimentation.
@2clicker - I'll start a VXR thread as soon as I feel comfortable enough to release this to the public. Given the first one cracked after 20 bowls, I was a bit hesitant to create a thread for something with durability issued. Even if the product never comes out, at least the video gave you some insight into the VXL engineering team and some of the different things we are doing here to innovate in the vapor space.
Quick Question - Let's say the VXR is durable enough with the new method of more even heating with a lower flame. Would you guys be comfortable purchasing this type of vape knowing that if you heat it improperly, it could potentially break? Price point for something like this would be similar to HDVape or Vapocane or any other vape in this genre.
