Therefore, a composite, and NOT obsidian. That's like saying gold and silver mixed together is "still true gold". It isn't. It's a mixture of gold and silver. And I highly doubt they took all this into consideration when giving Cinder her powers. It's more likely that it isn't obsidian at all, because there is no bright, clear, transparent form of obsidian. If they were to give her the powers of obsidian, it would probably be black, which is what people first think of when they think "obsidian".

Still, was a fun and rational debate. I appreciate it. It's refreshing to debate with someone who isn't namecalling the entire time. Gold and Silver are elements, not compounds, so anything that dilutes them to any degree is an alloy and not true gold or silver. Obsidian (or any glass for that matter) is already a mixture of other materials, meaning dilution and impurities do not change what it can be identified as.
