Pretty much... sounds like you may not have quite enough oxy in your flame. Try turning the oxy up... or the propane down. Not sure if you're running concentrators or tanks...
The haze should get burned off and stay off. Work it hot and keep in above glow the whole time... the longer you keep it white hot, the brighter it will strike.
If you're trying to work too large for your torch, this may also be a problem. Work small enough that you can keep the gather smokin hot.
If you give me more info about torch and oxygen supply, I might be able to give more specific tips.
