This innovative approach transforms the marks left by cold drinks into an aesthetic element. ## Features of Handblown Glasses The GRINN collection is made from soda-lime glass using traditional glassblowing techniques. Each piece features a unique base geometry that guides condensation along a specific curve. ## Formation of the Smile As a cold drink cools the glass, warm air collects moisture, which follows the curve in the base. This process takes 15-30 minutes, depending on the temperature contrast between the drink and the room. ## Diversity of the Collection The GRINN collection includes five pieces: Classic Glass, Highball Glass, Mug Glass, Beer Mug, and Carafe. Each piece applies the same engineering principle to a different vessel. ## Material and Usage Constraints GRINN glasses are designed only for cold and room-temperature beverages. Due to the soda-lime glass material, hot liquids and sudden temperature changes should be avoided. ## The Significance of Design GRINN demonstrates the power of design by making an ordinary act worth noticing. The smile, a natural result of condensation, emerges through the combination of structure, temperature, and time. ## Sources covering this story - https://www.yankodesign.com/2026/07/15/lift-this-handblown-glass-and-find-a-smile-left-behind-by-your-drink/?utm_source=rss&utm_medium=rss&utm_campaign=lift-this-handblown-glass-and-find-a-smile-left-behind-by-your-drink — --- _Summary written by Brifing from the original reporting.
