Barium sulfate was heated in a copper foil pan with a MAPP gas torch until it melted forming a thin crust. Then, the crust was broken and the BaSO4 was stirred with a marble rock. The center part was then heated until it was incandescent. I believe the roasting created barium oxide as well as a small amount of barium sulfide (from thermionic reduction of the sulfate ion).
Why are there two colors of fluorescence? The blue seems to be related to heat and to the interior of the heated (and melted) material.

...\FL min Experiments\Group II Sulfides\Calcium Sulfide w Mn
FOV: 4.5" wide.
Approx. 1mL of strontium carbonate, 1mL of sulfur, about 1mL sodium nitrate, 1mL of sugar and about 0.01mL of manganese carbonate was ground together and placed on top of a piece of chalcedony. It was ignited with a match and immediately burst into bright yellow flame which burned for a couple of seconds. This resulted in a hard grey melted substance that was quite luminescent.
This mixture was named "Gorn Powder" in reference to a Star Trek episode wherein an alien (the Gorn) was defeated using a mixture of a nitrate, sulfur and carbon (aka "black powder").

Scientific evidence confirms that Clostridium difficile, MRSA, VRE, Acinetobacter baumannii, and influenza are transmitted via environmental surfaces. Studies indicate that only 50% of environmental surfaces in a typical operating room suite or patient room care in hospitals are effectively disinfected. Hence a patient’s risk of contracting a Hospital Acquired Infection (HAI) from contaminated surfaces increases when the previous room occupant was infected.
- Mobile ultraviolet light (UV-C) unit significantly reduces aerobic colony counts and C. difficile spores on contaminated surfaces in hospitals.
- System for clinical & domestic applications to perform a proper air and surface sterilization against microbial contamination.
- Effective in the eradication of dust mites and bed bugs when used periodically.
- Prevention against indoor air contamination such as bacteria, mold, yeast and fungi.
- Decontamination of patient rooms, hotel rooms, meeting rooms etc... using an automated mobile UVC Light Unit.
- Short wavelength sterilization method to break down microorganisms in food and water.
- Variety of applications, such as food, air and water purification.
- UVC radiation destroys nucleic acids in organisms.
- Deadly effect on micro-organisms, pathogens, viruses and molds.
- Sterilize drinking- and wastewater.
- Air sanitization and purification.
Ultraviolet astronomy photos taken with telescope on moon, Apollo 16.
Disclaimer: I am not endorsed by NASA, I have done this out of intrest for the Apollo Program in my free time.
File information:
This set includes Apollo 16 UVC scans from NASA converted to JPGs by Thomas.
This set also includes unconverted scans from NASA, with a RAW prefix and .raw extension. The latter can not be read by conventional image software. For more information on how it was scanned, see NSSDC link below.
To get the RAW files, see 'Download options' window and click on 'SHOW ALL'
Why, and story:
The Apollo 16 UVC experiment photos are not all readily available on the internet. Original files have been received by NASA by asking here:
nssdc.gsfc.nasa.gov/nmc/datasetDisplay.do?id=ASUV-00017
At this website you can read how the raw files were decoded into image files viewable by modern operating systems: www3.telus.net/summa/faruv/explain.htm
Usefull Information:
The Revised S201 catalog of far-ultraviolet objects inspects some images in detail. A great source of information.
From Ganjam, Orissa India comes this 4" wide specimen.
Contains:
Ruby (FL Red >Green-UVab)
Cordierite (FL Blue >UVabc)
?? (FL Yellow, Tan >Green,UVabc)
Shown under UVc light.
Key:
WL = White light (halogen + LED)
