Once again two entries and two similar techniques.
H - Resist with Latex
After tracing letter & border into the clay I've put some liquid latex into a small nib bottle for easy application, well almost. After a few practice runs I finally got the hang of it thankfully latex is easily removed when a mistake happens!
I've added colour with black underglaze and used the spatter method with an old toothbrush, once dry the latex is peeled off.
Finished H - sanded, dry and ready for bisque.
I - Resist with Shellac
As per I've traced the letter into the clay and outlined the border.
With a fine brush shellac is applied to the letter and border. Once the shellac has dried a damp sponge is used to wipe back the clay.
In the bisque firing the shellac will burn out revealing the raised letter and border.
