Adding Handwritten Text into Silver Clay pieces
The easiest way is using a sharp solid point (like the end of a burnishing tool).
You need to wait until the clay is dry (or it kicks up messy edges). Sand & prep the area where the name will go then write your lettering using a soft pencil.
Lightly scrape the name onto the clay, support the work well as you do this (so you don't break it). Repeatedly scrape over the same lines building up depth. You'll find a kiddies paintbrush helps remove the dust, which you can keep for making slip. Fire the piece and polish it as normal.
Tip: To make the text stand out even more, apply a liver of sulphur patina and then re-polish the piece.
