Yes, I would definitely like to find about this screen deal.........but I have seen what lies on the other side of the mouthpiece screen by unscrewing the screen piece but it is tricky to do without the proper tool that GHL uses. There have been previous photos of all the pieces inside the mouthpiece but they are scattered throughout the thread and the previous GH thread. I can tell you that the main piece is the screen that has 3 "tabs" that are bent into place to hold it tightly to a threaded piece of metal that is connected to a cone that is made from a heat resistant material. There is another cone that sits on top of the screen/cone piece ( vapor goes from chamber to screen to first cone to second metal cone to mouthpiece exit hole). These cones look like they serve as a type of heat shields that insulates the very tip of the mouthpiece. The second cone looks like it is made out of copper, at least it's copper in color. I think you can reclaim collected residue inside these cones but they are very tiny and without the tool, it may not be worth it, although it is possible.
First Photo: first cone inside mouthpiece. The screen connects to the wide part of this cone and the outer edge of the cone is threaded which holds it in the mouthpiece
Second Photo: The actual mouthpiece screen with tabs that hold it into the first cone
Third Photo: The second and final cone inside the mputhpiece. Looks like copper to me but I'm not sure. This cone is in direct contact with the inside of the mouthpiece tip. Its a cone sandwich and I think they designed it like this to help reduce the transfer of heat to the outside of the mouthpiece tip where you inhale from. Hope this helps answer your question
