Presume we have a small-scale merchant in Renaissance Italy. By "small scale" I mean someone who has a shop and a house but isn't big enough to be a "rich merchant". I believe that something like this existed in Elizabethan England, where a merchant might have his family dwelling above and shop below in a small, two-story house. I'm presuming that something equivalent existed in Renaissance Italy, but I could be wrong, so I'm happy to know that as well.
I'd like to know which household items such a family would see as non-negotiable. That is, every merchant might have different things just due to what they sell and/or make, but perhaps every single such family would have a collection of pots for their own personal use. I'm using the "small scale merchant" as an economic class, not necessarily because I'm interested in merchants themselves. I'm just trying to distinguish them from farmers, and am expecting them to be in a city of the time.
