water boils at 212 degrees which is a little cool for powder coating but what id do is get your water and eggs on the burner and right after the water starts to boil give the egg three or four minutes to get it to temp then take out, dry, and use the copper egg holder to dip in the fluid bed. might have to go over it with the heat gun easily to help it flow out then bake it off at the desired temp and time. remind me to not have any of your deviled eggs right after easter
