Since the cast of the marks left over on the ledges did not turn out great, I went back a second time to try it again.

I smoothed the bottom of the clay before pressing it onto the bench to get a more effective print.

Once I had the printed marks, I brought it back to college and made a cast.

I left the plaster set for about 25 minutes and this was the final result.

Better than the last one I think!
