As autumn unfolds, the Open GLASSroom is in full creative swing. 
While the project is nearing its completion, the community continues to grow — and so does our open collection of learning resources. 

Over the past two months, twenty-two brand-new videos have been released, covering everything from fracture mechanics and façade systems to sustainability, fire resistance, and cutting-edge glass innovations. 

Each video is part of one of the five Open GLASSroom collections on edusources.nl, and is accompanied by openly licensed teaching materials such as papers, transcripts, and translated subtitles. 

And this is not the end — more videos are coming soon, so it is worth checking back regularly! 

Glass Codes & Standards

Browse Collection 

Effective Thickness Method 
Martina Eliášová – 12 Oct 2025 – CC BY 4.0 
Explains how polymer interlayers and temperature or load duration affect composite action. The EN 16612 “effective thickness” method leads to more accurate and economical designs. 

Comparative Analysis of the Glass Plate Design 
Ivana Rakić, Nebojša Buljan – 26 Oct 2025 – CC BY 4.0 
Compares new and existing standards (FprEN 19100 vs. EN 16612 vs. ASTM E1300). Demonstrates how the new FprEN enables more cost-efficient designs for heat-treated glass. 

Glass Fundamentals

Laminated Glass Production 
Martina Eliášová – 27 Sep 2025 – CC BY 4.0 
Explains laminated glass composition (PVB, EVA, ionomers, TPU) and its post-fracture capacity for structural applications. 

Float Glass: Primary Manufacturing and Mechanical Properties 
Mauro Overend – 12 Oct 2025 – CC BY 4.0 
The Pilkington process explained — how molten glass becomes annealed float glass, and why its structure defines elasticity and brittleness. 

Float Glass: Secondary Manufacturing and Mechanical Properties 
Mauro Overend – 12 Oct 2025 – Material link – CC BY 4.0 
Strengthening through tempering and laminating, with a focus on post-fracture safety and durability. 

Glass Processing

Julian Hänig – 29 Oct 2025 – CC BY 4.0 
In this presentation from glasstec 2024, Julian Hänig introduces sedak tempered+, a tempered glass designed without visible optical anisotropies. 
Using precise light-scanning measurements, sedak developed a technology that eliminates the rainbow-like stress patterns of standard glass, creating perfectly homogeneous façades that meet the most demanding architectural expectations. 

A Novel Approach to Artificial Fracture Pattern Generation 
Leon Bohmann – 29 Oct 2025 – Material link – CC BY 4.0 
Numerical simulations of fracture patterns calibrated from over 130 tests — a cost-effective alternative to physical testing.
