Saeid Esmaeilzadeh created the world’s hardest glass in a “failed” experiment

A researcher profile by filmmaker Folke Rydén

Saeid Esmaeilzadeh is Professor of Materials Chemistry at Stockholm University and currently runs several successful companies. This film explains how he produced crystals when a furnace suddenly malfunctioned. Instead of cooling slowly, the melt solidified much faster than usual, leading to a rock-hard glass material with very interesting properties. Based on this rock-hard glass, the company Diamorph was founded, a materials development company focusing on glass and ceramics. Diamorph’s glass material is now used in such products as roller bearings, wind turbines and medical implants. The company has received VINNOVA funding on a number of occasions.
