Wow, reading that article brought back memories. Where it says "you occasionally see new materials show up in your inventory..." I remember the time I threw something away by mistake (I think it was Graphite) and then I couldn't build anything with that block because it's not a naturally occurring material. But I got it back later after I learned about alchemy.
