Soldering with human cremains revisited

A while back I put out a question on soldering on a wg box
containing human cremains. We have now completed this project and
all went well. The ashes are safely inside and the box is soldered
shut. I was a bit anxious about having it blow up on the final
solder but no problem. It is a pretty heavy piece with the top/face
cast from the deceased’s old ring. Now we have other inquiries about
jewelry pieces for cremains so it seems to be a new emerging market.

Thanks for all the helpful tips.
