Oh wow .. big question. Pottables get their purity from the pot they're planted in, the initial plant, and the humus used to plant. Crop purity is a mix of the field purity, seed purity and a random factor. The random factor can push field purity up and thus you can improve on both fields and future harvests.
Ore purity increases with distance from the ladder inside the mine, as well as a random factor that is affected by the amount of +mining and +productivity bonuses you have from gear.
In turn metal purity affects a butchering knife's purity, which can be used to butcher animals and have them inherit the purity of the knife. Metal purity also affects fishing hooks which are crafted into lures that can be used to get fish with the purity of the initial metal used in the hooks.
Alternatively, the purity of the fibres used in making a netting for a fishing trap affect the trap's purity, and the fish inherit that purity if they're caught that way.
Purity adds to the gluttony and regeneration effects of food. at 100% purity, your food will have double its normal values at 0%.
Exactly 6.022 x 10^23 worth of Lach molecules.
