Also, are there any tricks or weird little things that a sculptor who is planning on making a bronze statue would do? I mean, other than the modeling-plaster-bronze sort of simple things. Details. In fact, maybe even, little_details.
Edit: Apparently, there is a difference in terminology. In the UK, what I'm referring to is called plasticine or polymer clay, whereas a lot of Americans refer to the non-drying, oil-based clay as "modeling" clay.
