Fuller always went on about alloys and their unpredictable qualities.

theconstructor.org: What is Transparent Aluminum?

Quote:
How is transparent aluminum manufactured?
ALON is produced by combining aluminum, oxygen, and nitrogen. The manufacturing process involves pressurizing aluminum oxynitride powder to 15,000 pounds per inch in rubber molds submerged in hydraulic fluid. The obtained material, which is molded and opaque, is heated to 2000oC and kept at this temperature for two days. Once cooled, ALON emerges transparent, which is then ground and polished for extra clarity and strength.
