mignonette,
A lot of the boro colors are heavy with metals (silver) and have a 'haze' that must be burned off to get the best colors to come out and they often need to be worked 'hot'. When you heat the rod look closely at the edge where the flame and rod meet. You will see a haze that will recede as you heat the glass. This is the haze that you need to burn off. Momka does not show the rod on her color charts so her colors are a bit hard to identify by seeing the splotch on the poster. Most boro colors are like that...the finished color bears no resemblance to the rod color.
