    When you put candle wax/grease in the melting pot to bring impurities to the top it will create a flash fire. This is the only Flash I can think of that is being mentioned.

    I had a friend introduce me to sinker making. I have yet to read the intructions that comes with the molds. Not saying that I could not learn something from them, just never got around to reading them.

    Flash is that little bit of lead that you get on the seam of a sinker if the mold doesn't close goodand tight.

    that would be called gates. let me give you an example of a flash, hot lead and a cold ladle. when you dip it in the reaction is a flash or blow back. this is a time you can really get burned bad. the lead explodes. this may be what it means.

    The rev's right. It's called casting flash. It's present on anything casted. Engine blocks, tie rod ends, etc, etc. The gate is a chunk you have to cut off from the fill hole.

    That,s it.If you,re getting a lot of flash from your molds,they,re either wearing out or you got your lead temperature too hot.

    Even if you do get flash you can always take a metal file and rub it off. I have an old jighead mold that always leaves flash.

    You can take em into a machinest shop and have em put on a truing block its just a block that vibrates and is covered in fine grit. it will retrue the mating surfaces by giving them a even polish.

    i have a 12 oz bank sinker mold that had alot of flash on it.... being i work in a diecast plant and know the kinds of thing that causes flashing i got to looking at my die and on the bottom it was warped... another thing i had was a small piece of lead i seen on another one that was causing it to flash... there are alot of things that can cause it.
    i know this is an old thread but just found it... flash looks like aluminum foil ussualy thin like paper...

    Yea It is a really thin strip that stick out about 1/2 a centimeter from the sinker. And it is only in one cavity in a 2, 3, 4, 5 bank sinker mold. But I have had alot of bad luck with this mold Handles went bad right away. So i think it may be warped from being too hot. But im not sure If it is bad I can get one for $25 at bass pro so no huge deal. It has deffinatally paid its way off x 100
