You got it.
After the initial cool down and flame strike it is often just necessary to back out of the flame a few seconds to check the color and if it is not as you want go right back in the outer flame. Once striking is started, the object should never get back up to melting temp and only just get a bit of glow....almost. If that makes sense. A lot of boro color rods will 'show' you the darker degree of strike possible if you observe the dark color line near the tip after using a portion of the rod. That little band of color often represents the darker shades possible thru striking.
