I went ahead and changed the wording. It makes more sense your way.
I base my theory on the idea they are making crafting like fallout and that they good at making games. In most games, crafting is poorly balanced. Crafting a weapon takes a lot longer then buying a weapon. By the time you can scrounge up the blueprints, the ingredients and the crafting bench, you will be fairly high level. Fallout 3 understood this. They didn't try to fight it by making it easier to craft, but just accepted that it was a long time consuming thing so they made the items you craft ultra strong and with abilities that no other item had. That way they will be strong and useful no matter when you finish them.
Crafting low level items is hardly worth the effort needed and you risk out leveling their range of usefulness before you finish. I can think of an example from oblivion, I wanted to craft a potion of invisibility, but in the time it took, I was able to level my illusion skill and buy an invisibility spell. Same thing will happen if you craft basic items. By the time you gather up the iron, you will be using steel.
You make all levels of items to sell to other people......just like all the blacksmiths in TES games.....
Obviously you could also make gear for yourself and special customized stuff you found the blueprints for, which required you to gather special components for constructing it. See the forging in Shivering Isles as the basis for these examples.
Dwemer items and gear? I doubt it. More likely we'll get a few special things along those lines, but I'm almost certain we'll be able to craft more common items than ultra rare super powered ones.
They are exactly recipes but for technicians who understood technology, Last Dwemer understood them well, but I doubt he still live if an Telvanni Wizard is not achieve his goals, as well some Telvanni members understood work of Animunculi,

Sotha Sil improve certain dwemer techs and expand them at new technology stage, Imperials use dwemer technologies like Numidium and Dwemer Airships, there is armors and equipment based on techs of Dwemer, like Dark Brotherhood goggles and scavenged Animunculi armors.
I think person who understood crafting well, if found certain books and schemes can use technologies of Dwemer.
Is English a second language for you, buddy? I'm guessing so, based on many of your posts, including this one. I was suggesting alternatives to the OP's word choice because recipe does not apply in the context of his idea.
Examples:
Alchemy -
Recipes for potions and poisons which use
ingredientsCrafting/Smithing -
Blueprints for weapons, armor, and items which use
components and
materials
