In technical glass production, molten glass is pressed and rapidly cools as it is removed from the mold. This rapid cooling creates internal stresses within the glass piece. Annealing is the controlled process of slowly cooling glass to relieve these internal stresses. Kopp's annealing process provides the solution for the elimination of these stresses in technical glass lenses. Kopp develops proprietary annealing schedules for each unique product design to ensure maximum stress removal. Factors influencing these schedules include glass composition, coefficient of thermal expansion and glass thickness. Check out our other videos by visiting our channel / koppglass
It’s satisfying to see glass annealing done right.
Yes I searched for this video
Me too, bit i work in glass.
Same. Trying to cut lenses for a custom light fixture and the glass keeps breaking unpredictably. Fun fact, if you have a pair of polarized sunglasses and a monitor, you have a polariscope! Put on the glasses, pull up a white background, and rotate your head to the side until the screen appears to be black. Then look through the glass at the screen. Anywhere there is stress it will alter the polarization and show up as a lighter area. Checked the glass using this method and sure enough the internal stresses were high and spotted all over the plate.
awesome
Wow
