For one thing, it helps give it added stability, as each coil is threaded onto the coil below it. Also, using the coiling technique, it is possible to build thicker or taller walled vessels, which may not have been possible using earlier methods. The technique permits control of the walls as they are built up and allows building on top of the walls to make the vessel look bigger and bulge outward or narrow inward with less danger of collapsing or cracking during firing.

Coiling is among the most ancient forms of pottery making. The potter forms coils by rolling clay and then builds up forms by stacking the coils on top of each other and attaching them with liquid clay or slip. The coils are then usually smoothed over, making a smooth surface. Native American pottery is usually made this way and then the pots are covered with colored slip and decorated.

The clay is rolled out like pastry into a flat slab. Then these slabs are cut, joined, curved and shaped to form the pot.
White vinegar is a tried and tested method for removing water stains from most items. It should work well for pottery, see the natural method below: Natural Formula to Use: Pure white vinegar Method to Use: 1.Fill a clean spray bottle with pure vinegar 2.Spray the vinegar freely over the pottery and wait for a few minutes 3.If stains are stubborn spray more vinegar and wait a while longer 4.Simply wipe away with a clean cloth

The traditional method for preparing water dumplings involves making a dough with flour and water, rolling it out, filling it with a mixture of meat or vegetables, shaping it into dumplings, and then boiling or steaming them until cooked.
The traditional method for making sfogliatelle involves creating thin layers of dough, filling them with a mixture of ricotta cheese, sugar, and citrus zest, and then shaping the dough into a shell-like form before baking until golden and crispy.
The most common method would be to study the style of the pottery - decoration, form, and so on.Beyond this, thermoluminescence - a property available for test on objects that have been buried, is a more recent technique. And requires precautions.More Information:One method is the radiocarbon dating of organic materials concomitant with the pottery artifact.Recently (ca. 2003), a method of radiocarbon dating the lipids, embedded within the pottery material itself, has been developed. Now, for the first time, direct dating of the pottery is possible.
The traditional method for making persipan involves grinding almonds into a fine powder, mixing it with sugar and water, and shaping it into a paste. Some popular recipes that incorporate persipan include persipan cookies, persipan cake, and persipan marzipan truffles.
Actually it isn't always the best method, but it is quick and inexpensive to do making it a very popular choice for electronic connections. In high vibration and/or high thermal stress environments spot welding of the component leads is a much better method of making electronic connections.
