Items in Trove can be created with the different workbenches. Either they are decorative or useful, like the Chromatic Alterator, a machine, that can produce new kinds of blocks. One not fully can separate items and ingredients, since a lot of items become ingredients in certain recipes. To create an object, the player must "learn" several Recipes, a lot of these need a previous item produced, so the next item can be done. Usually, to learn a new recipe costs some Template:Gem.
Most of these have become obsolete!
