Plaster is easy to work withTurned out great!
How did you make the form? And did you make the edges with dremel as well, where the writing fades into the "stone"?
I made a mould with clay and filled the plaster in.
Just write the text into the plaster with a Dremel and easy sand all at the edges to fade out.
I plan to make a silicone mould, because I'm worried to break the tablet, because it's just plaster.
With a mould I could reproduce my tablet if I would break it
