Where is clay reported to appear?

Pro Game Guides describes clay as brown patches scattered across the map and recommends noting their positions so you can return when a recipe asks for the material. The article does not provide a versioned map coordinate list in the captured text. Use the color description only as a search lead. If a location or node looks different in your game, rely on the current map and item prompt rather than assuming every brown patch behaves the same way.

What is clay used for?

The same guide connects clay to pottery and to later building recipes. It also reports a pottery recipe that turns clay into a plate used in a fishing-rod quest. Those are useful connections for planning, but exact ingredient counts and every building recipe are still pending confirmation. Check the recipe shown by your current crafting station before gathering a large stock.

What should you do if the recipe is unavailable?

The guide reports that pottery crafting depends on a technology unlock. If you already have clay but cannot use it, inspect the Building branch and the active quest requirement before collecting more. The exact node cost and all alternate clay sources are unverified. This page keeps those details out until a current-build screen or second source confirms them.
