For many years now, solder couldn't contain lead so all solder today is an alloy of Zinc, tin and other soft low melting point metals. The yellow is from the zinc burning. Don't inhale those fumes, they are dangerous, use a respirator. It's also why your copper didn't pour very smooth, you alloyed it with other metals and changed its properties.

Yes you are right. The part of the pipe used to join it together with the threads will be brass.
Yellow could be from impurities/oxidation. Looked like the joint were soldered
I was thinking perhaps zinc or lead?
@@backyardfoundry Zinc that's in the brass.
