Eindhoven design studio BCXSY used hand-blown glass in six grades of opacity, from transparent to white, to create a collection of glassware for Japanese design brand Inframince (+ slideshow).

The In Between collection of glasses, bowls and plates was produced by BCXSY for Inframince as part of the tilde_objects 01 collection shown at the Design Tide Tokyo trade fair last weekend.

"A closer look at pieces, which at first glance may appear identical, reveals the uniqueness of each piece through slight variations in shape, colour and dimensions," according to the designers, Boaz Cohen and Sayaka Yamamoto, who founded their studio in 2007 shortly after graduating from Design Academy Eindhoven.

Other glassware we've featured on Dezeen includes a series of engraved carafes accessorised with metal collars and a set of frosted glass decanters which echo the Istanbul skyline.

In Milan this year, BCXSY presented stools, tables and bowls made in collaboration with traditional boat builders as well as a collection of rugs woven by Bedouin women.

Harmony and gradations in glass

One of the greatest appeals of hand-blown glass is the delicate balance between imperfection and near-perfection, reflecting both the nature of the material and the skills of the maker. A closer look at pieces, which at first glance may appear identical, reveals the uniqueness of each piece through slight variations in shape, colour and dimensions.

In Between is a hand-blown glass tableware collection, consisting of drinking glasses, bowls, plates, and accessories of various types and sizes, which come in a six-step gradation – from transparent to white.

The subtle successive changes are enhanced through the use of the pieces and the way they harmoniously combine. Besides emphasising the artistry required for reproducing such variations, this also encourages the exploration of different compositions and applications. More playfulness and awe are now introduced to the table.
