Occlusal plant parallel to bench top
side walls parallel to posterior teeth
maxillary pointed in front and mandibular rounded

Crystal growth and outward thrust
thick mixtures have more or less expansion
more expansion cuz more crystals and more heat
increasing mixing time does what to expansion
Increases expansion

30 degrees condylar inclination
the lock in centric position
incisal pin at )
platform at 0 degrees
what should be checked before mounting casts
all nodules removed before mounting
