I was reading through some blogs and came across this one from Garciela http://glyntpottery.blogspot.com/2008/08/why-pot.html
Very interesting note. I think mugs are the most intimate thing a potter makes. It is a simple form but creates this intimate connection between the potters hand and the user. When I drank first out of a hand thrown mug... I couldn't help but think who made it, whose finger marks are those, glad they made the lip of the mug in such a way that it felt so soothing to me, the handle was made for me to hold it.
Every potter I know is always perfecting their mugs. They want their work to be individual and at the same time make a connection with every person who buys them. So from being a very simple form it becomes a very complex execution.
Below you can see my transformation of cups starting from earliest to current and I am still learning to make the perfect mug!
