Abstract. We report high speed etching of glass (Pyrex ® 7740) substrates using an inductively coupled plasma (ICP) reactive ion etching (RIE) process employing sulfur hexafluoride/argon (SF 6 /Ar) based chemistry.

Micro-Hole Drilling on Glass Substrates—A Review
2.1.1. Mechanical Drilling . Mechanical drilling is the most conventional and relatively low-cost method to drill micro-holes in glass. Most often, peck drilling (depth of cut is sub-divided into small drilling cycles []) is applied to evacuate chips created inside the holes during drilling [].Reported aspect ratios vary from 0.33 to 3.96 with corresponding …

Pyrex: How It's Made
The process was labor-intensive and expensive. Slumping sales in a depressed market forced Corning to turn to professional consultants who ultimately recommended cost cutting through automation. Thus, after 1929 the production of Pyrex was changed to a machine-pressed glass process. Corning was able to reduce Pyrex prices by as much as half.

The PYREG technology carbonizes your residual materials into pollutant-free, highly porous biochar.Unlike rotting or incineration, this process does not release the carbon contained in the residual materials as CO 2, but binds it stably in the biochar and thus removes CO 2 from the atmosphere. This makes the production of biochar one of the Negative …
