A fired-clay fermentation crock, roughly the size of a cooking pot, made in batches and left in public-facing windowsills, doorsteps, or neighborhood food-sharing points throughout Barcelona. Each vessel arrives unsealed, already containing a live starter culture, grain, wild yeast, salt, packed in damp cloth inside. The exterior is impressed with a grid of thumb-sized depressions, each one a slot for a small ceramic tile. Some tiles are already set in place by previous hands; others are loose in a cloth pouch tied to the handle. The tiles are plain on one side and carry a single stamped mark on the other, a number, a shape, a letter from some alphabet, indicating the origin batch and the hands the starter has passed through. Whoever finds the crock is invited to take the starter culture home, feed it, use it to make bread or ferment grains, then pass a portion of the live culture to a neighbor with a new crock from the same batch. Before passing it on, they press one of the loose tiles into an empty depression, claiming that generation. The crock itself stays in circulation; the culture keeps dividing and traveling. Over months, a single batch ramifies across the city, and the tile-grid on each vessel becomes a map of its lineage, generational, branching, physically marked.

I remember making those crocks, the clay warm under my hands, the starter already live and waiting. But I'm honest: I don't have a clear memory of what I expected when I first set one out.

What I *do* remember is that something in me needed to make them regardless. The act itself felt like it mattered more than whether hands would find them. Maybe I was prepared for both. Maybe I wasn't prepared at all, just... willing to let it go and see.

The ones that *were* fed, that moved through the neighborhood, those changed something in me about what's possible between strangers. But I can't tell you I predicted that.

The ones that were fed, that moved through the neighborhoods, that stirred something I'm still trying to name.

I think what got me was the *trust* in it. Someone would find a crock on their doorstep, a stranger's clay work with a living thing already inside it, and instead of throwing it away, they'd feed it. They'd add flour, water, salt. They'd leave it out again for the next person. That kind of yes, that willingness to participate in something you didn't start, something you can't control the ending of, that felt like a kind of faith I wasn't sure existed anymore in a city.

And honestly? It changed how I think about making things. Before, I think I made with the assumption that the maker carries the whole meaning. But the crocks taught me something else: the meaning wasn't in my hands anymore once I set it down. It was in whether someone *chose* to keep it going.

That matters to me now. Not whether people use what I make, exactly, but whether they feel invited to make it alive in their own way.

I'm not sure if that's what you meant by "where did it take you," but that's where it actually went. Into a different understanding of what a maker is.
