with brass alloys, if you think it's hot enough, then it really isn't, lol
[6:06 AM]
when your scooping the dross off, you should see green/yellow flames where your scooping, and a small steel rod, it should wet to it and not ball up on it
[6:06 AM]
just heat it up first to preheat it and drive off any moisture
[6:07 AM]
a steel coat hanger would work perfect for that, just stick it in the metal and stir it around very gently to make sure everything has melted, and when you pull it out, it shouldnt have anything on it except where it wetted to it
if you take a piece of aluminum wire, just a small, short section and sit it on top of the melt right before you pour, do not mix it in, just let it sit on the top of the melt as you pour. when you pour, the aluminum will help the brass wet it's way through the mold and flow into the mold easier, and you'll end up with a white powder on the cast part, which you just brush off with a wire brush
and I'm not talking about a massive piece of aluminum wire, just a very short section, like 3/4" section of 1/8" aluminum wire at largest
yea, higher temperature is the best bet
I usually wait till every last piece is melted down into the crucible, then skim the dross and everything off of the melt, put it back into the furnace and set a timer on your phone for 10-15 mins depending on how well insulated your furnace is and how good your burner is, then go directly from the furnace to the mold(edited)
you can scoop the dross off right before you pour, but you shouldnt have much since you skimmed a few mins before, so very little to no time lost there
the second you take brass alloys out of the furnace, your on the timer and every second counts
you can try an extra 5 mins, but I usually let it heat up 10 mins
some people's furnaces/burners aren't that great, so I said 10-15 mins

since your using an electric furnace, that'll help
you'll want to use the thin walled temps
