NGA volunteers update Glass Technical Papers (GTPs) through the systematic review ballot process on a 5-year cycle. The GTP FB22-24 Proper Procedures for Fabrication of Flat Glass Mirrors was updated in April and is now available to download for free in the NGA Store.
Silvered flat glass mirror products can be fabricated to provide additional aesthetic appeal such as beveled edges and surface accents. As additional fabrication features are applied, it is critical to ensure proper conditions and techniques are utilized during every step of fabrication to protect and maintain the integrity of the mirror backing and edges and to reduce the chances of black edge developing.
NGA offers 88 Glass Technical Papers free to download for everyone. Find them in the NGA Store.
