Other popular events include the Glass Olympics, and Blowing In The Dark - a night-time demonstration of glass-blowing by students from the Wanganui Glass School.
Ms Craig said tickets to Blowing In The Dark were strictly limited, and this year for the first time tickets were required for entry to the Glass Olympics, although the cost was only $5.
"It's great that the event is so popular but unfortunately it's become almost too popular for its own good."
The festival headquarters will be in Taupo Quay (near Caffeinator), where visitors can buy event tickets, buy glass and view exhibitions, including one by the Wanganui Glass School's current artist in residence, Samantha Jones.
The Quay Gallery at the Wanganui i-Site will feature Snapshot, a showcase of New Zealand artists working in glass.
Visiting American glass artists Evelyn Dunstan and Ethan Stern will give public talks and also hold advanced glass workshops for glass artists, which Ms Craig said was a important part of the festival.
"It's not only about exhibitions, it's also about upskilling our local glass community," she said.
Last year's festival was estimated to have brought an economic benefit of around $200,000 to Wanganui, and $30,000 worth of glass art was sold during the festival.
Around 40 per cent of the 2012 festival's 2000 visitors were from out of town.
Ms Craig said 2013 festival brochures had just been printed and were available at the Wanganui i-Site, galleries and other locations around the city.
