Do you think one could make a mold using this metal and then cast Urethane resin into it?
I’ve read that Woodsmetal, if cast into long strips can be used like solder..if thats true that what are the flow properties of woodsmetal? does it soften as it approaches its melting point or does it stay hard until it gets then then “poof” suddenly becomes fluid like solder does?
ALso, after becoming liquid, how long does it stay like that before it hardens? again using the solder example, it’ll return to a solid pretty much as soon as a heat source is removed..

Just a note, those weighted bricks have a piece of steel in them, not lead. Any yes, I did take one of them apart.

How much safer is it, really, than metallic mercury? No question that organomercury compounds are nasty, and that you should keep your mercury in a sealed container, but I’m not sure that metallic mercury is really very bioavailable. Whereas all that cadmium is foul stuff…

I'm not just a Blogsome user - I'm their current number one Sample Blog, I'll have you know! I don't know whether this speaks to the excellence of my blog or the crappiness of all of their others, of course. More MAKE-ey stuff for visitors from the MAKE blog: Dumb stuff in microwaves, electrolytic rust removal, IR photography, a MAKE product (sort of), sparky stuff, and, of course, The Secret Life of Machines.

Found this through the Make: blog. Fascinating! You’re also a fellow Blogsome user, so that gives you two stars in my book. :)

I wonder what reaction would be prevoked if one were to fill someone’s home or office keyhole with this metal. While it wouldn’t make a key impression or anything, it would make the owner wonder how the heck that happened if they were unfamiliar with this metal.
