Awesome Glassblowing

A dual-layer glass drinking vessel helps insulate its contents thanks to the air gap between its layers. But how do glass manufacturers sandwich those layers together so precisely? This fascinating factory video from Process of Everything shows how skilled workers cut, heat, and connect glass tubes to create these insulated drinking bottles.

The artists of Seattle Glassblowing Studio make some amazing glass objects. In this clip, you’ll see how they take molten Kugler Colors glass and shape it into a glass cheeseburger that looks good enough to eat. They don’t show the finished piece in the video, but they’ve posted a pic of another one on their website.
