Kirksite ?
I think that is what I want . it melts at approx. 400* F plus or minus a few.
Where can one purchase the stuff?

Kirksite melts at 725 - 750. Look on the internet. There are several places that sell it. I just completed making a hammer form from Kirksite. I need to make eight aluminum trunk lids with a license lamp relief. The lamp relief is to be hammered in once the panels are wheeled and welded. The sample is thin aluminum so it could not withstand the heat of a direct pour. It took several tries to create a mold that could withstand the heat of the pour. The two cleanest were from concrete and plaster of Paris which I took off the original sample. Be sure to bake the molds to get them very dry. Any moisture remaining in the mold will instantly steam out and cause occlusions in the Kirksite. Some minor touch up is required which I can do with my jewelers torch and some fine sand paper.

Yes, RotoMetals. They refine and cast/extrude various lead/tin alloys. Body solder and fluxes, too. A great old SF Bay Area company.

thanks everyone ,
I was hoping to find it closer , but they might have straight tin ingots that I would like also . If I have to pay the freight ,might as well make it worthwhile. Any one have a ph. number or address for these folks . Don

Don Houseman has given demonstrations on how he makes pullmax dies from kirksite. There may be a video floating around the internet.

In response to the question posed in the link, I attended the Santa Cruz meet. Simple dams to corral the pour were made from sheet metal trimmed for the task.
Keep in mind - for design purposes - Kirksite is great in compression and relatively poor in tension. The demo used Kirksite for both punch and die. Drop Hammer punch and die combinations include lead and zinc for the dies. Every so often the press is cycled, without material inserted, to "reconstitute" the die. FWIW
