Regular cleaning of the nozzle, and flow rod also cuts back on it.Alot of the inclusions is the actual pot liner scaling, or a sign the lead needs fluxed. Certain fluxes (marvaflux/clean cast) also causes the liner of the melter to rust and corrode, which is why I wont use that stuff.

I have yet to read a manual or article that state you need or should smelt/render in seperate melters.

Most electric melters will not get hot enough to melt zinc weights, they just float to the top. Same with steel weights. I also find I have to turn down the heat on my electric melter when casting - you can read the the bullets on how they cast (they get a frosty look to them) to know when. Never used a Thermometer, never needed it with an electric caster.

Most Zinc weights are marked "Zn" and Steel "Fe". If you in doubt -snip the corner with a pair of cutters, it should cut fairly easy if it is lead alloy. If it wont budge - toss it, its useless.
I think he was asking about a hybrid alloy that is both lead and zinc and not just how to separate them.

I also expect that bottom pour pots will also leak almost no matter what you do, it's just how it is with the pots that we can buy.

I am using two pots because I load up around 40-50lbs in the pot. I am not yet casting bullets either but am measuring the hardness of my lead blocks prior to casting to see if anything needs added.

Looking at my stainless pot i'm using it's pretty dirty in the bottom and i'd prefer to do it in two stages. It's personal preference I guess.
