Potter’s wheel
While the term itself is pretty self explanatory, many people don’t know its actual name. The potter’s wheel, as the name suggests, is able to rotate. The potter puts a lump of clay on its surface, and by spinning the potter’s wheel is able to create different cylindrical objects, be it cups, pots, bowls, etc.
This skill is relatively easy to learn, and it can be done in a short period of time. However, just like with any other skill, actually getting good at that requires a lot of practice. You might be able to create some simple objects, but creating complex, proportionate and aesthetically pleasing pieces is a whole different thing, and cannot be done that easily.
