The modern glassmaker
An evening pause: Though the last two minutes are a commercial and can be ignored, the rest of this video shows the modern way glass is produced for our technological society. Most fascinating, especially because the way it is done surprised me.
Hat tip Rocco.
Readers!
Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.
3. A Paypal Donation or subscription:
4. Donate by check, payable to Robert Zimmerman and mailed to

Very transparent, unlike Washington!
Is it possible to make glass on the Moon? To become completely Earth-independent, we need to.
The answer about glass on the Moon depends on where you are and what else you are doing. Oregon L5 Society’s Research Team has used a concept for our Lunar Development Settlement for National Space Society in the virtual world, Second Life, using the basalts of a lava field with a lava tube cave in it, before the end of Phase 1 with in situ resource facilities for producing 3 things:
1. ) Making Liquid Oxygen from regolith electrolysis, which leaves leaves waste highly enriched in reduced Iron, as well as the native Nickel/Iron bits from meteorites pulled out of the the regolith by magnetic rakes before it is fused.
2.) Making the LOX process waste yield Iron Pentacarbonyl and Nickel Tetracarbonyl through the Mond Process, and distilling them to separate the 2, as well as separating the Nickel/Iron bits and their PGM residue. This produces a waste product highly enriched in alumina and silica.
3.) Alumina and silica is most of what you need for high strength “S Glass” fibers from a glass furnace with a spinneret at the bottom and a coating process to keep the glass fibers isolated from water. Calcium from the lunar regolith can be added to lower melting points for separate glass batches. This can be used later with the high melting point fibers, allowing the sort of glass-in-glass composites that Dr. Goldsworthy demonstrated as early as the late 1970s.
Note is this sort of multiple usage of material collected that will lower capital costs for settlements, which costs, after cheap transportation is available, will be their chief limit.
