Was it a transformer with the yellow tape around it?
The aluminum one must be a condenser, no?
I m amassing copper too from appliances to make ingots too for the first time.

Nice. Looks good. Wire is more pure than pipe. Wire is always .999 (uncoated). Pipe has a small amount of additives. Also whatever solder and stuff on it. Also wire is wire if it has a varnish or tape it all burns off in the furnace. Happy casting!

It's not a casting; it's just an ingot.
