list of important posts/ "Old and decrepit"
|
Hey Paul, amazing post. Please feel free to write any time you wish, as you have what might seem like a limitless amount of experience in the area of industrial optics and related. Thank you for writing, it's very fascinating. I had to right away check my heavy metals test to see where the beryllium was, and fortunately it did not register, as the measurement was less than the detection limit.

Your last line seems to deviate from the rest of the post, but brings up a good question. Perhaps it's a worthy thread to pursue on the Zambuto mirror group. I guess it would be on-topic. Maybe it's time to write on the subject and tell more of the story. The question was asked, what am I going to do with the business when I get old and decrepit? Perhaps it's time, because the subject is indeed on my our minds here at ZOC. When I can, I'll take some time and fill in a lot of items that may relate to it all. But I'll start it off by saying, in truth, I AM the business. And like just about every other cottage industry shop, it is intrinsic to this property, as it was developed here, where the land and buildings are a critical, integral part of all of it.?

There are many aspects to this query, as in many factors that apply. Again, when I have some time I will write. Meanwhile if anyone wants to weigh in and say anything about the subject, please feel free to do so. The subject is wide open as far as I'm concerned.

Carl, Beryllium is not normally on a heavy metals OSHA listing but is a hazard class similar to Lithium, Thorium, Phosphorous,? Sodium, Magnesium, and Hydrogen. All are a severe fire or explosive hazard. Some are capable of causing lesions and considered cancerous. Is OR as stringent as CA about hazardous materials ? My son never said anything while working in Bandon but is very cautious about contamination, especially biological toxins. He had to move his family away? from one apartment because the high humidity caused the growth of mold and mildew. ? Supposedly, one can swallow a small block of Be and it will pass through the gut? before it will damage the lining of the stomach. I would not try that, though. Most of these elements are used to color fireworks. It seems you were successful in coating mirrors with aluminum without greatly increasing scatter. The deposition process results in collection of microscopic beads of the pure metal but heating can fuse the beads into a continuous layer and lowers the scatter coefficient. ?We did the same heating to drive out moisture and fuse electroplated Gold over Nickel, which slightly improved reflectance and bandwidth. This results in better reflectance in? SWIR - short wave Infrared as well as the Far Infrared beyond Thermal. ?Good Luck, Paul On Wed, Aug 21, 2024 at 2:37?PM stedystate via <stedystate=[email protected]> wrote:

Paul, thank you for replying.?

The amount of scatter of aluminum in our thin film deposition is based on an electron beam depositor. We run it at about 10 angstroms per second. When we turn on the quartz, it goes much slower and we use ion beam assist to lower scatter and improve the smoothness.?

On the subject of becoming "old and decrepit"...

I don't follow OSHA per se. I recently did a provocative metals test following EDTA chelation therapy and had urine sent to a lab in Indiana. It went overnight FedEx in a cold package. This is about general health because in my most recent studies I'm coming to the conclusion that heavy metal toxicity is the basis for many if not most degenerative diseases. That of course is another discussion and is off-topic. However on-topic might be toxins that are work related, in this case optics fabrication. My last career was a plumber, and it was long ago enough in history that I did melt lead. The highest reading I had was lead at 19 ug/g creatinine, it should be less than 1.1. Lead has a half life of 30 years in the body untreated. We also used to handle lead in this shop as weights, we have since wrapped them so there is no more direct contact. With chelation therapy over recent months my lead level has been cut in half. Other metals have also improved markedly, and just for general information the list is below. BTW I had uranium show up in my blood. That is also another discussion, probably not related to this forum. I had seven on the list below show up outside the reference range, in other words high enough to take notice. (The uranium is now below detection level.) The seven that did not show any detection at all were Beryllium, Bismuth, Palladium, Platinum, Terrarium, Thorium, and Tungsten. Everything else on the list showed up and was measurable in the first provocative test.

MS Spellcheck deserves to be included in a list of environmental pollutants. On Sat, Aug 24, 2024, 7:14 PM Mike Rock via <mikerock=[email protected]> wrote: Don't you just hate it when 'Terrarium' shows up!? We kept two turtles |

I wonder if it sold have reported Tellurium rather than 'Terrarium'. I don't know if it fits into the heavy metals category? For years, I worried about Acetone but it is a natural component in the blood. Of greater concern is overheating polishing pitch, especially if based on Asphalt. Norm Brown reported that burning pitch can cause lung cancer. It was a real? concern in CA.?I think, however, that Norm died of natural causes. He dropped? out of Nuclear?Energy as a young student as soon as he realized it was a dirty? business.? I have a friend that was?an advocate for using nuclear power, but under safe? handling procedures. He is?now in his mid-eighties, like I am, and has no? unusual diseases. I think he does not?consider himself 'old and decrepit' and? works out regularly.? It is thought that the Arctic Explorers, British sailors, on the Andersen Expedition? looking for a?NorthWest Passage. Many died of Tin poisoning from the metal? cans holding their food. The rest resorted to Cannibalism but then froze to death. If the Voyager Interstellar spacecraft had not used electric power?generated by? radioisotope generators, they would not be still broadcasting about interstellar? and Solar 'winds', 45 years after launch.?? At one time, researchers thought that Alzheimer's Disease was caused by? exposure to Aluminum, like from pots and pans. I think that has been disproven. Glad to hear that you solved the problem of light scatter in Evaporated Aluminum? coatings by using a different deposition process. Your customers get that benefit ! Paul V. ??
