Glass Artist: John Dosa aka Dosa Glass

Dosa Glass' work stands as a testament to both his artistic vision and his technical skill.

When discerning collectors discuss the most prominent figures in the glass art industry, John Dosa is consistently cited as a leading favorite. He has garnered widespread acclaim for his impeccably clean reticello patterns, a signature technique that has become synonymous with his name. But on top of that, his mastery of shaping should be highlighted. John’s amazing attention to wall depth and clean connections is par to none. As someone fortunate enough to spend time with John, I have to say that his art is a direct reflection of himself and his dedication to mastering anything in front of him.


Whether a solo creation or a collaboration with some of the biggest names in glass, a Dosa piece is instantly identifiable by its crispy, meticulously spun lines, clean shaping and seals executed with absolute perfection. To fully appreciate the distinctive Dosa technique, it’s helpful to refer to the definition provided by the Corning Museum of Glass: Reticello (Italian for “glass with a small network”) is a type of blown glass crafted with canes that, when arranged, create a delicate net. This intricate process often results in tiny, intentionally trapped air bubbles, adding a subtle dimension to the finished work. 

John’s mastery of reticello and his ability to adapt it to a borosilicate form elevate this traditional technique to another level. He showcases a profound understanding of glass with a dedication to precision. His work stands as a testament to both his artistic vision and his technical skill, making him a true icon in the contemporary glass art world.


Based out of the mecca of glass art that is Bellingham, Washington, when John’s not on the torch, you can find him tackling single-track trails on his dirt bike and experiencing all the things the PNW has to offer while always enjoying some El Fuego sauce.
