An Inconspicuous Table

G'day, trying to make a content mod for hanging vessels but I'm out of my depth getting it to render textures in game, display names correctly or have functional recipes. They are in the creative menu, can be placed/broken, have the vessel lid animation and the correct shape [just missing texture]. I'd be happy with it only working for one colour of vessel (black or brown as they are the pit kiln ones) Any help would be appreciated (or if you want you can use the shape I made for your own mod) https://github.com/InconspicuousTable/hangingvessels

G'day, I'm getting an intermittent crash but only in LAN multiplayer. Crash doesn't seem to matter on location and happens every 15minutes to 6hrs I can only use lan to host multiplayer as my router doesn't have the right settings. Crash log below spoiler.
