So what sort of metal is this?

There is no spoon.

A bit of a rush to see if this works - I'm sure someone else can do a much better job.

 

How many gm needed to make that 1oz coin?

 

Specific gravity of silver vs gallium says it should be 17.5g but this coin weighs about 23g (although it's a bit wonky)

 

First attempt (thanks to Ag47 for the gallium)
Was using the kid's playdough, but it was probably too soft. Not much details on the pour :|

 

Good first attempt Lunarowl, you should try it with wax

 

And try it with a high relief lunar dragon

 

Great idea! Definitely will show lots of details!
Now.. Who has a spare high relief dragon and don't mind my KFC fingers on it

 

I used to use a metal we called "fullers" metal , i think that was the spelling. it looked and felt like lead, but it melted in boiling water. I used to do a lot of intricate pipework on engines and the like. We would melt the metal, pour it into the seamless tube and let it set. we would then bend the tube in all sorts of shapes without risk of flattening on corners or deforming. the metal made the pipe as easy to bend as a solid metal bar. we'd then put it back in the water bath, melt the metal out and runa borescope up the tube to make sure we got all the metal out. This stuff sounds like it could be one of the metals used in making fullars.

 

Is that not "Wood's" metal?

Edit: Found it - Woods is the toxic one as it used lead - melts at 80-90

Fields metal melts at 60ish

 

Could be? Maybe Fullers was a trade name or something? It definately melted very close to boiling point , it wouldn't have been 60 deg
