There is a sticky here on strawing too- or maybe the other luger forum.
Just search on straw, strawing, re-strawing or similar and you can find it.
For those challenged in degrees C- a nice straw color is obtainable from 420 to 460 degrees F, the range depends on the accuracy of your thermometer, time, metal, and phase of the moon.
It can be done in your "regular" oven; and re-done if it does not turn out to suit the first time.
Just re-polish to white and do it over.
