DIY Material Guide: Polymorph Plastic ( a thermal plastic with low melting point)

Step 2 A toy maybe?

Here's a Lego size figurine made with the fantastic stuff, the idea was to embed a flashing led powered by a button cell battery for a fickering heartbeat, cute? Never quite got on with that.

Out of curiosity, not malice - but is the polymorph moulding fine enough to create a mold for a key? I was thinking of placing the key on a solid surface, then covering the side in polymorph then repeating the other side (depending on the grooves running down the side). I'm aware of the fact that two pieces of "molten" polymorph will stick to each other so I thought this way might work...
Of course then it'd be nice to find a low melting-point metal with a high tensile strength so the copy wouldn't snap in the lock and leave evidence *I mean* mess up the lock ;)

Hi,

I think it is possible to mold the key, but I suggest you coat thinly, the flat surface with vaseline, and do likewise with the key, wash and dry your hand before pressing the impression with polymorph.

But I doubt you can get a casting metal that would meet both the requirements of low melting point and tensile strenght.

What about coating the inside of the mold with vaseline and placing polymorph in the mold, so the vaseline ensures that they don't stick/melt to each other? 
Or does polymorph not have that much tensile strength to make it viable for key making?
Good idea with the washing/drying - could get messy I guess.
Really good quality smoothing on the model btw.

did you mold him by hand?I want to know because i want to go get me some polymorph right now, or atleast gonna try(don't know where to find it!)
