One thing I learned about this is that not every casting material
will behave the same way during casting and curing. Resin-based parts
typically retain the shape in which they're made, but some quick-cure
casting compounds will warp to an amazing degree as they cure.
In other words, buying a casting kit expecting to use some other
casting material is not necesssarily a good idea.
