The Importance of Fabrication Prior to Heat-Treatment - Downloadable Out of Stock
Glass fabrication after heat-treatment may weaken the glass
Glass applications frequently require a variety of glass edge and/or surface fabrication. Some common fabrication processes include edge seaming, grinding, and polishing; hole drilling and notch cutting; and surface grooving, sand-blasting, and etching. GANA recommends against glass fabrication after heat-treatment because it may weaken the glass and/or cause it to break. This document discusses why. The Technical Services Division of the National Glass Association (NGA) has produced this Glass Technical Paper solely for informational purposes. This Paper was developed by dedicated member volunteers and subject matter experts. This document was first published in December 2013, and updated in 2018.
