I did my first sculpture in 1982. I played with carving and molding concrete. In those days I was limited by the state of the art in those days, not to mention a lack of readily available information.
Nowadays, there is a plethora of information in the internet. I have recently used what I have heard with experiments of my own to develop a mixture that is serving really well to sculpt and carve with. It is hard, long lasting, colorful and the materials are all readily available. If you are interested, contact me.
I love making utilitarian sculptures that function as a usable device and as a work of art. Below is a work in progress that will be a mailbox holder:
My old mailbox holder was a concrete knot that was hit by a car:
