Iridescent Nassau Tumbler by Sirius Glassworks

“The original multi-colour Nassau Cup.

These tumblers vary wildly and each one is a pleasure to gaze at. The decoration can range the full spectrum of opaque and transparent colours, earth tones, jewel tones, primary colour blocks, sparkly bits and mood ring areas, dots, lines and squiggles. Made by rolling handfuls of re-purposed and recycled colourful bits onto molten glass, that is fused and formed into a cup and then iridized. Each cup is entirely unique.”


Dreamy hand blown glass tumblers by Sirius. A lovely gift or gift for oneself. Each glass is subtly different from the next.

About Sirius:

Sirius Glassworks is one of the longest running art glass studios in Canada, established in 1976 in Port Colborne. Sirius was Peter Gudrunas' creative vision for several decades, making coveted vessels with proprietary colour melted from scratch. From 2013 onwards Peter has worked in collaboration with his daughter, Iris Fraser-Gudrunas, who introduced contemporary iterations inspired by the Sirius archives. Since Peter's retirement in 2021, the studio continues as a legacy business under Iris’s direction.
In our technologically sophisticated time, glass retains even more of its historic mystery- every piece is made by hand and will never be duplicated.
Please note: handblown glass is not dishwasher safe, and is vulnerable to extreme temperatures. Do not use with boiling liquids.
