25/04/2018 -Silver Polyfilla
After removing the sprues from the castings, it becomes clear that the mold cutting in this area went a bit awry.
Instead of a raised seam that could be removed, there is a recess where I assume the mold pieces were not joined up on exactly the same level.
This is a real problem as there is not enough metal to file down far enough to remove this chasm.
I tried filling one with solder, but the colour difference is too obvious.
I could use silicon burrs to at least smooth out the holes, but that just wouldn't be up to my standards.
Luckily I have a secret weapon.
I'm not sure if they make it anymore, but I have some ArtClay Oil Paste at home. It's an oil (rather than water) based version of fine silver clay which is mainly used to join pieces of fired silver clay together (instead of solder).
I basically used this as silver "Polyfilla" and filled up the holes.
