Season 4

Ten glassblowers hit the hot shop to create pieces that show off their signature style. But when scale is a factor, will they rise to the occasion?

The artists design sculptures that celebrate what they wanted to be when they were kids — with pieces inspired by botanists, stunt performers and more.

The glassblowers take cues from natural wonders with vivid, gravity-defying installations while working in teams.

Channeling their dark side, the contestants bring to life mutant mushrooms, creepy krakens and evil eyeballs for this spooky challenge.

Lollipops, gummy bears and hard candies decorate the showroom as the artists make colorful, supersized confections for a tricky treat-based challenge.

Inspired by kids' imaginative illustrations, the glassblowers prepare one-of-a-kind pieces including a top hat-wearing snake and a flame-throwing robot.

Passions flare as the judges task the five remaining contestants with creating pieces that pay tribute to causes they care deeply about.

The glassblowers put their presentation skills to the test by creating two pieces — one hanging and one sitting on a pedestal — that work cohesively.

The heat is on for the semifinals as contestants craft a pair of Venetian glass pieces: a quick-blow goblet and a highly detailed vessel.

In the fiery finale, the last two standing look to be the best in glass by designing an immersive installation. Will their pieces blow the judges away?
