       Silly idea: Monocrystalline rock candy.I'm thinking you start with a normal polycrystalline rock candy block, break off one of the larger crystals as a seed, maybe polish or something to reduce defects on the broken surface, then lower into a supersaturated sucrose solution.Then let it grow for a while and hopefully extract a relatively clear, defect-free <100> sucrose crystal.

       The dream would be your entire candy piece is like a 10cm or more long single crystal

       @azonenberg So, will it laze?

       @penguin42 LOL sucrose as a laser gain medium? I don't know enoguh about the physics to know if this is at all plausible

       @azonenberg Then you have to figure out how to dope it to produce n and p varieties...

       @azonenberg @penguin42 Sucrose is incredibly birefringent as I recall. so peering through a crystal in most directions (apart from along optic axes)  would show double images. Could be fun!

       @idiot Interesting about the dust acting as seed crystals. I could see that making it challenging.

       @idiot And it decomposes before melting so you can't do Czochralski.But glucose melts at 146C and doesn't decompose until 188C from some quick reading. So Czochralski glucose crystals might be doable?

       @GyrosGeier ooh that's an interesting idea. The big problem with sucrose though is you can't melt it, it decomposes basically at the melting point so you can't get a clean melt to crystallize.But glucose probably could work that way
