As a novel glass forming technique created in the middle of the 1st century BC, glassblowing exploited a working property of glass that was previously unknown to glassworkers; inflation, which is the expansion of a molten blob of glass by introducing a small amount of air to it. That is based on the liquid structure of glass where the atoms are held together by strong chemical bonds in a disordered and random network, therefore molten glass is viscous enough to be blown and gradually hardens as it loses heat. 8K resolution refers to an image or display resolution with a width of approximately 8,000 pixels. 8K UHD (7680 × 4320) is the highest resolution defined in the Rec. 2020 (UHDTV) standard. To increase the stiffness of the molten glass, which in turn facilitates the process of blowing, there was a subtle change in the composition of glass. With reference to their studies of the ancient glass assemblages from Sepphoris of Israel, Fischer and McCray postulated that the concentration of natron, which acts as flux in glass, is slightly lower in blown vessels than those manufactured by casting. Lower concentration of natron would have allowed the glass to be stiffer for blowing. Red Digital Cinema was founded by Jim Jannard, who had previously founded Oakley. As a self-described "camera fanatic" owning over 1,000 models, Jannard started the company with the intent to deliver a (relatively) affordable 4K digital cinema camera. Jannard dates this idea to a time when he bought a Sony HDR-FX1 video camera and learned that the files had to be converted with software from Lumiere HD and were not viewable on Mac OS.Lumiere HD's owner Frederic Lumiere collaborated with Jannard on developing an alternative and introduced him to Ted Schilowitz who became Red's first employee.
