Chain slip - Cycling Mob: Road Cycling, Mountain Biking and More

I just put a new chain on my Sears 12 speed road bike. Went for a ride
and the chain slipped a tooth on the smallest rear sprocket, every
crank revolution or so, under moderate and heavy pedal pressure. It
finally quit slipping after the first 15 miles or so. The only
condidtions that changed during the ride are (A) the temperature
warmed from 40F to 55F and (B) the chain got dusty from the ride on
the gravel road.

I should also mention that before putting the new chain on I boiled it
in grease, let it cool then wiped it with a rag. It was VERY well
lubricated.

The sprocket teeth look good. Very symetrical from front to back as
opposed to being hooked or worn otherwise. Is it common for a new
chain with good lubrication to slip on a freshly cleaned sprocket?
