Do they embalm prior to cremating?

Depends on state law. In Texas, a deceased has to be embalmed if not interred within 24 hours of death.

Now, if cremation occurs immediately, there is no requirement for embalming anywhere in the States.

If a family wants a viewing for a couple of days, embalming is a necessity, unless they want their friends to view a swollen, smelly mess.

Just as an aside, morticians have been killed in such explosions.

Being hit by a red hot crematorium door isn't healthy.
