	Dirts that are high in clay but contain larger particles as well may be separated using a sedimentation pit. Create two pits, one of higher elevation. Put the raw dirt into the higher pit and wash it with water to suspend the clay particles, allowing the heavier sediment to sink to the bottom. Create a channel allowing the clay-rich water to flow into the lower pit, where it will settle out, similar to a river delta. Finer particles will be found further from the input channel. Once most water is gone, a thick slurry can be collected.		Dirts that are high in clay but contain larger particles as well may be separated using a sedimentation pit.

			Raw clay is seldom ready to use. The addition of grog (previously fired clay dust) can increase strength and decrease shrinkage. The addition of starch can increase plasticity. To add starch, boil starch rich foods such as rice and potatoes to extract the starch. The water can then be added to dry clay to create a pottery medium. The addition of starch will create odors as the pottery dries due to decomposition.

	Clay tablets are the earliest known medium for writing, used in Sumeria and Greece as early as 3000 BCE. Symbols can be inscribed into wet clay using a stylus, and the clay can either be remolded to record a new set of symbols or fired to make the record more permanent.

	~~== Natural sources ==~~

	Clay can be gathered from riverbanks and dry riverbeds or lakebeds in almost any part of the world. Wet clay is slippery even if it is unprocessed, unlike other kinds of soil or sand. A sample of clay can be tested by wetting it to a workable consistency and seeing if it breaks when rolled out or coiled into shape. A good sample of clay will be easy to work and resistant to breaking.

	~~===Processing===~~

	Before using clay, impurities such as stones and plant matter should be removed. This can be done by picking the impurities out while the clay is dry, by sifting the clay through a sieve, or by filtering clay particles suspended in [[water]] by passing them through a cloth. If clay is intended to be used for ceramics, it can be tempered with sand or with ground up bits of broken previously fired ceramics. This will improve the chance that the clay fires successfully. You can also add starch to your clay mixture, obtained by boiling foods such as rice and potatoes. Once boiled for some time, the starchy water can be added to your clay mixture to make it more moldable allowing for more precise pottery. Keep in mind that after adding this to your clay it will likely start smelling horrible after a couple days as starch is an organic material and will be decomposed.
