I have had the same problem with the pour spout dripping. What I have found is to take a teaspoon of borax laundry powder and add to the lead pot and stir it around several times. this makes all impurities to clump removing them with a spoon. I tried wax for removing impurities and found to be extremely flameable. ]
I really appreciate all the great info on this site.
I'm a new member to this site, but have read up and learned very much. Started slow, but have caught on. I used the candle for a release and it seems to be working well - making sure the molds are warm/hot before pouring - and all the great tips. Have been just pouring jigs and really like what i see.
Yet - this is where i need help. I have a bottom pourer and it seems to clog up very easy. I took a drill bit to push through the bottom. It works, but now I can't even a drip............
It's a little frustrating, but am progressing carefully.
Would really appreciate the board's expertise.
