Just wanted to tell anyone who's interested that I tried making a pot from "ciment fondue" as per a book I bought on bonsai. The proper cement mix "ciment fondue" was very difficult to locate. But it works! It's a lot easier than "hypertufa" as you don't have to make a mold and pour it. The "ciment fondue" is the greatest medium - it's stronger and "finer" than regular portland, kind of feels like working with cake icing. Just figured someone out there might be interested. I'll be making more projects out of this stuff - many more bonsai pots and pads and maybe even a treebeard or a hobbit hole!
