OBhetos a Collection of Usables is a collection of diagrammatic and minimal shaped vessels for holding and making or infusing any hot or cold, beverage, or liquid.  Bowles and Linares looked at widening usual perceptions of the shape, material, size and use of vessels and wanted the designs to be produced in the thinnest glass possible with the additional property of resistance to heat.  These qualities could only be found in borosilicate glass and they aimed to transfer the blowing and making techniques for laboratory glassware truthfully to these objects. Not only are they heat resistant but also surprisingly light and stronger than expected for such thin glass.
