Wheal Martyn China Clay Museum

This is the UK's only museum dedicated to China Clay. As well as discovering the history of china clay, you can explore the old workings and see how they turned the white rock into the clay from which fine poreclain is made. |more things to do| 

There are water wheels, settling tanks and lots of old industrial stuff to look at. There's also a nice walk up through the woods to a look-out point. From here you can look down into the quarry from which china clay is still quarried today. Get there at the right time and you may even see them blasting. Very interesting place to visit. |map| |nearby attraction|
