About Cali Drinking Glass

The Cali glassware series, a creation by Officina Endorfino, blends personality with functionality. Its stackable design not only extends the product line but also subtly evokes the elegance of a chalice. The series features three distinct sizes, all crafted from borosilicate glass. This material allows for various color combinations and its unique properties create captivating reflections, playing with perceptions of volume, weight, and gravity. Additionally, the product packaging is made from recycled cardboard.

Within the continuum of contemporary tableware design, Florian Seidl's Cali Drinking Glass collection represents a thoughtful meditation on the intersection of functional utility and sculptural presence. The designer appears to engage with the longstanding tradition of elevating everyday objects through considered formal intervention, recalling historical precedents where master glassmakers transformed mundane vessels into carriers of aesthetic meaning. Each glass in this series demonstrates a sophisticated understanding of material properties, exploiting the inherent transparency of glass to create visual experiences that shift dramatically depending on viewing angle and light conditions. The distinctive pyramidal bases, with their precisely faceted X-form geometry, introduce an element of structural surprise that challenges conventional expectations of drinkware stability while simultaneously creating opportunities for playful interaction and tactile engagement. The chromatic choices suggest a deliberate palette strategy, moving from the deep aquatic tones of viridian through transparent neutrality to the fresh cerulean with its unexpected warm foundation, creating a collection that functions both as individual objects and as a harmonious ensemble. Technical accomplishment is evident in the seamless transition between cylindrical and geometric sections, where the junction appears optically continuous despite the dramatic formal shift. The capacity markings visible on each vessel indicate practical consideration for measurement and portion control, grounding the artistic ambition in functional service. This work invites contemplation of how objects of daily ritual might elevate mundane moments into occasions for aesthetic appreciation, transforming the simple act of drinking into an engagement with light, color, and form.

Production Technology
The Cali glassware series is made from borosilicate glass. The material is known for its strength, durability and temperature resistance. The glass can be moulded and crafted in a variety of very different shapes and thicknesses. It is an infinitely recyclable material that can be re-melted again and again minimizing waste and environmental impact. The packaging is made from recycled cardboard.
Design Challenge
The main challenge was the necessity to create a series of modular and stackable drinking glasses in different sizes that also explore the formal possibilities of the material and make a visual statement.
Project Duration
The project was designed in Italy during the summer of 2024 as a quick side study for Officina Endorfino. A free exploration and exercise in glassware design.
Operation Flow
Take a glass. Fill it up. Bring it to your mouth. Drink. Enjoy!
Research
The design process was based on conceptual and formal research aimed at understanding material properties and opportunities of the category.
Product development and refinement through traditional sketching and 3D modelling.
Inspiration
Cali has a lot of personality and perfectly fits the identity of Officina Endorfino. The stackable design extends the product line naturally, while projecting its very own character. The shapes used merge the existing form language with a remote echo of an elegant chalice. The main body appears to be floating like a dream on top of the delicate but stable base. Cali dreaming.

Design Interview about Cali Drinking Glass

The design is a subtle re-interpretation of a classic chalice.

A colourful, lightweight and elegant drinking glass that is stackable and comes in different sizes. A free exploration and exercise in glassware design.

It would be great to see Cali succeed on the market.

The concept was developed in parallel with other ideas during the summer of 2024.
A quick side study for Officina Endorfino - the process took about month.

The design was developed as a personal project.

This is still an ongoing discussion with several potential partners.

I think there Is a place for colourful and well designed drinking glasses. Cali started out as a side project and quickly turned into something really special.

Not really.

The target customers would be interested in well crafted design objects that have a unique identity.

The design is following a modular, stackable concept. Cali comes in three different sizes.

The name uses the first few letters of the italian word "calice". This seemed fitting, given that the shape and initial inspiration.

From simple basic sketches directly into 3D.

The unique shape and material allow for many different colour combinations.

Cali is a personal project.

Production and material technology play an important part. The Cali glassware series is made from borosilicate glass. The material is known for its strength, durability and temperature resistance.

The design process was based on conceptual and formal research aimed at understanding material properties and opportunities of the category. Product development and refinement through traditional sketching and 3D modelling.

The main challenge was the necessity to create a series of modular and stackable drinking glasses in different sizes that also explore the formal possibilities of the material and make a visual statement.

I wanted to share the project and create more visibility. Hopefully the award is only the first step!

The whole project was an interesting opportunity to develop unique design ideas in the area of glassware.

Get in touch for interesting collaborations!
