Memorial pendant, Your beloved Ashes melted into a glass cabochon and set into sterling silver.
I can melt ashes into glass in my kiln, Base glass colour of your choice is fired in the kiln several times  until I can get the correct size, then ashes are added and several firings of clear class are fired on top to fully enclose the ashes into a glass cabochon.
This is when my silversmithing skills will work to enclose the cabochon into sterling silver, resulting in a sterling silver pendant with memorial ashes.
All ashes are treated with utmost respect, I only need a quarter teaspoon of ashes. I only use one animal or human ashes at a time when firing to prevent cross contamination
