Material-first design thinking transforms laboratory aesthetics into memorable hospitality experiences.
A beverage floats within its vessel, suspended by invisible walls of air and glass. The Tube drinking glass collection by Florian Seidl creates precisely this optical phenomenon through a double wall structure that recalls laboratory test tubes housed within transparent cylindrical supports. Designed during summer 2024 for Officina Endorfino and recognized with a Silver A' Design Award in 2025, the Tube collection demonstrates what happens when designers allow material properties to drive formal decisions. Borosilicate glass, the same material used in chemistry laboratories, possesses exceptional thermal resistance, clarity, and durability. Seidl's approach began with understanding what forms borosilicate naturally enables. The answer: a modular series of three stackable tumblers sharing identical diameters but varying heights, each showcasing the suspended tube effect that transforms every pour into visual theater.
For hospitality brands evaluating drinkware investments, the Tube collection illustrates several transferable principles. The three sizes (200ml, 330ml, 500ml) maintain consistent 85mm diameters, enabling mixed-size stacking that reduces storage footprint in commercial operations. The double wall construction insulates beverages, keeping cold drinks cold longer while eliminating the condensation that leaves water rings on tables. Borosilicate's infinite recyclability supports sustainability messaging with genuine material credentials. Most compellingly, the chemistry laboratory aesthetic creates natural alignment for establishments emphasizing craft cocktails, molecular gastronomy, or innovative beverage programs. When a guest lifts a Tube glass, the floating liquid effect becomes a conversation piece and a photograph waiting to happen. Tableware selection represents an often-overlooked touchpoint for brand expression, and the Tube collection demonstrates how material intelligence combined with cross-disciplinary inspiration produces vessels delivering both function and visual distinction.
Material understanding precedes formal innovation. The Tube collection succeeds because Florian Seidl recognized that borosilicate glass already contained the design solution within its molecular properties. For brands developing products or selecting tableware, the methodology matters as much as the outcome: start with what materials genuinely offer, and distinctive forms emerge naturally from honest investigation.
