In this body of work I am exploring the glassworking techniques used by Heinrich Geissler. Geissler was a scientific glassblower and businessman and in 1857 he invented the mercury vacuum pump which allowed for better vaccums to be achieved and he produced the first low-pressure gas discharge tubes, now called Geissler tubes, that paved the way for modern Neon Signs as well as applications in electronics, television displays and many other fields.
