Porcelain has been a part of my pottery-making life for a number of years, since first trying to make pots in the SRU studio. It is emotional and unforgiving, that porcelain. But the beauty it brings is well worth the struggle. I have always had to be "in the mood" to sit down and throw pots with porcelain. An elegant material, porcelain ought to be thrown thin, with rims and edges that compliment it. Trips to Standard Ceramics to pick up clay usually include getting some porcelain. Opening the bag and taking a whiff of its special scent (not odor) gives that reminder of this special material that often comes seemingly as soft as cream cheese.
But working in porcelain is an acquired taste and the unforgiving personality of the material demands extra attention to how you handle it on the wheel and timing when you attach pieces. The window of opportunity for attaching a handle for example is smaller than stoneware and other clays. Well, that is just a point-of-view I suppose. Because what porcelain really needs is treated differently in every step and in that case of attaching, it needs to dry slower.
