    When getting ready to make sinker I lay my mold on top of the pot that I melt the lead in . As the lead heats up and melts the mold heats up as well. When the lead is melted and ready to pour the mold is already preheated. Saves pouring2 or 3 molds full of lead to heat the mold. Hope this helps.

    thanks for the tips ken, i just got my sinker mold today along with a hot pot 2 and melted down some lead and poured a few. heating up the mold was a must because with the molds cold i couldn't pour past the opening. however i got on the good ol' BOC and found the answer to my question. so i took a propane torch and lightly heated up my molds. after that it was smooth sailing...

    I've tried that and it helps, but it usually takes a little more, sometimes not.

    In case you have not read it anywhere smpking the molds real good helps the led pass through the opening and help the sinkers to release from the mold.

    Just thought of another little bit of info that might help someone!! I made a box of 1" lumber about 18"s square and 12"s tall, left out 1 side and the top to set my mold in while pouring in windy conditions. This helps keep the wind from cooling the mold off between castings. I use the little hot pot in this and it works rather well. One can build it to suit ones preferance for ease of working.

    Heating the molds prevents the lead from cooling down to fast,if you should have wrenkled sinkers, Half sinkers or the gate holes[mold pouring holes] stop-up your molds are still to cold. I use pam to lub my molds sinkers never stick.

    If your molds have clamps on them to hold them shut, Heat the gate as you pour, It makes them pour super smooth from the first sinker to the last.

    I heat my gates just before I start to pour the sinkers,the lead pours smoothly.
