What are handmade ceramics?
The most common definition of handmade ceramics is wheel thrown (made on the potters wheel) or hand-built (pinched/coiled/slab-work) ceramics.
These are unique art pieces made by the human hand.
What are the other kinds of ceramics?
Other than handmade ceramics there is also the slip-cast/mould-made variety. As the name suggests, the ceramic object is created using a mould. This is a very important method of making ceramics. This is the method chosen to mass produce ceramics.
