The wiki also describes hoppers extracting smelted items.WikiMinecraft Wiki: Furnace · Minecraft Wiki: Java Edition version historyrevised
   How we know

   Its interface can be opened by pressing the use item button on it. A fuel source (up to one stack of fuel items) is placed in the bottom slot, and the items to be processed (up to one stack) goes in the upper slot.

   Hoppers can now be used in conjunction with furnaces, allowing for automatic smelting.

   Furnaces drop their contents when broken, including XP from processed items that were extracted by hoppers.

2. ^ abcThe player crafts by laying items out on a grid to match a recipe: a 2×2 grid in the inventory for small recipes such as planks, sticks, torches, and the crafting table, and a 3×3 grid at a placed crafting table, made from four planks, for every recipe. Most recipes are shaped: the ingredients must sit in the right places relative to each other, though the pattern may slide and be flipped left to right. Some are shapeless and take their ingredients anywhere on the grid.WikiMinecraft Wiki: Crafting
   How we know

   Players craft by arranging items in the crafting grid to match a given recipe. Small crafting recipes that are at most 2×2 can be made there, including wooden planks, sticks, crafting tables, and torches. … The crafting table can be made by filling the 2×2 grid with any type of wooden planks. This brings up an interface with a larger 3×3 crafting grid in which the player can use to craft any crafting recipe in the game. … Most recipes must have their ingredients placed in the correct relative positions on the crafting grid. These are commonly known as "shaped" recipes. Ingredients in shaped recipes can be moved up, down, left, or right. They can also be flipped horizontally, but not vertically. … Some recipes don't require their ingredients to be arranged in a specific way on the crafting grid. These are commonly known as "shapeless" recipes.

3. ^ abcdIn version 53.16, as the wiki describes it, an order at a workshop becomes a job that waits for a dwarf with the right labor. That dwarf fetches the nearest suitable material, nearest to the dwarf and not the workshop, or only from linked stockpiles if any are set, carries each ingredient to the workshop, makes the item, and leaves it there. Taking it to a stockpile is a separate hauling job, queued later, and items piling up in a workshop slow its work.WikiDwarf Fortress Wiki, "Workshop"
   How we know

   When there are items ordered at a workshop, the workshop will generate item creation jobs until it finds a suitable dwarf with appropriate labors … The dwarf finds the nearest, most suitable base raw material. This is nearest to their current location, not the workshop. If any stockpiles are set to give to the workshop, only linked stockpiles will be looked in. … The dwarf gets that material and hauls it to the workshop. The dwarf repeats that until all the necessary ingredients are in the workshop. The dwarf labors in the workshop for a while and creates the item. The dwarf leaves the finished item in the workshop. … A new hauling job is (eventually) queued to take the finished item to the nearest suitable stockpile. … If you have no stockpiles to put finished objects in, workshops will become cluttered. … The more items there are, the longer tasks will take.

   How we know

   Though no process can be truly automated, there are a few tricks to keeping your workshops productive.

   Thus, standing orders automate certain tasks, queuing them up whenever input materials are available

   Appointing a manager noble allows you to queue work orders using the job manager interface, though your manager will need time to approve work orders before production begins. … Firstly, it allows you to produce an exact number of items as opposed to putting a workshop on repeat, and secondly, it allows easier management of complex tasks … the tasks will simply re-queue, to be fulfilled as soon as the prerequisites are in order.
