See Chef Katie Pickens make her neon signs at Brooklyn Glass Workshop.

Signs made of neon are constructed in the exact same ways as when the technology was first used. The usage of neon signs has evolved with time. There isn’t the striking and vibrant signage of previous years, but instead more subtle, muted placements.

To begin, employ flames in order to mold the glass tubes. After that after which all the air has been removed from the tube with the vacuum device.

The final step is to remove any impurities in the glass tube by applying high voltage to it . At the same the vacuum pump removes the burned impurities. It requires a special transformer for this process; consequently creating neon signs from the past are not something you could do at home.

The second last step is creating a vacuum inside the tube prior to then pumping the neon gas through the tube. The lifespan of neon signs can be between 8 to 15 years when you do it correctly. bgt7j8m7sc.
