Does Your Hot Solder Drool and Cover Your Copper Wires Like Hot Butter?

Since i been doing leaded windows with reinforced zinc bracing i will put my 2 cents worth in. A few years back the EPA put a stop to 50/50 (1/2 lead and half tin)and 60/40(40 %lead and 60% tin) soldier for copper water lines.They also put a stop to flux with Zinc, So if you are going to the hardware to pick up flux and soldier ,you have to have a lot of heat on the new stuff, thats why plumbers uses torches. If there is a HOBBY LOBBY they keep the 50/50 and the 60/40 both in 1 lb rolls, and also any stain glass company that giver classes or sells to the stain glass material to the public will also have it. I use a 100 watt iron as it takes about 300 degree to melt solder, but a 60 to 80 watt iron will also met the older soldier, the new stuff at the hardware for water lines takes about 400 to 500 degree to make it flow like the 50/50,or 60/40. Dont use rosin core solder, just put the paste where you want the solder to go, if you check at some auto parts stores they have 60/40 in a real fine blister pack, its in the radio section about soldering wire and connectors, also some marinas keep it as well, but you get about 1/2 ounce at these places where with Hobby Lobby it comes in 1lb rolls.
