I made my very first combustion today *is proud* :D

Is it normal to see an orange glow for a split second in solid white pvc while firing?

I am using a shoe waterproofer with propane distillates and an unknown hydrocarbon propellant. It may contain heptane.

The combustion chamber is 2" nsf-pw sch 40 and the barrel is 3/4" nsf-pw sch 40.
