FRAGILE ARTWORK: Glassblowers Create Stunning Colourful Pumpkin

This footage shows how a beautiful colourful pumpkin gets made out of hand-blown glass by a skilled and experienced glass-blowing artist.

The images were obtained by Newsflash from the Decatur Glassblowing studio, which has been creating stunning glass artwork in Decatur, in the US state of Georgia since 2012.

Glassblowing is a complex glass-forming technique that involves blowing molten glass into a bubble with the help of a blow tube before moulding it into any desired shape.

In the footage, glass sculptors can be seen masterfully glueing little shards of coloured glass onto a larger, preheated piece before blowing it into a smooth pumpkin shape.

It took only an hour in the hot process to finish creating the glass pumpkin, but the final product is completely finished after 20 hours of cooling, according to Carli, the wife of Nathan Nardi, with whom they co-own the studio.

Each piece is a unique creation and goes through a different production process.

Carli said: "Some items like an ornament can be made in about 10 minutes in the hot process, but that's once we are all set up and ready to make several in a row. Other pieces can take several hours.

"Some pieces take months from start to finish if you consider the colour patterns being made in advance, finishing work, including if there is any hardware that needs to be glued, which can sometimes take up to one week to cure."

The studio owner and experienced glass sculptor, Nathan, mostly creates custom-made glass objects.

His primary artistic expression is the abstraction of natural form, which can be seen in all of his work whether sculptural, decorative, or functional, according to the studio's official website.

Artists at Decatur Glassblowing use a soda-lime glass with a COE (coefficient of thermal expansion) of 96, Carli said.

"Our glass is purchased pre-mixed and added to a furnace that runs 24/7 and melts it down at around 2,200 degrees Fahrenheit [1,200 degrees Celsius]," Carli explained.

"The coloured chips we used are called Frit. We purchase these already made. The colours happen when different metals and oxides are added to the glass: for example, cobalt is in many of the blue colours," she added.
