Photo from Crave Online 
This 4 x 4 inch example is in two layers with a process of printing dry frit through a custom made photo exposed silkscreen then adding loose frit to the top clear piece and moving the loose frit(size of fine beach sand) around to produce textures. I ws trying to get the loose idea of water or old cyanotype colors.
For this white base I dusted loose frit through a distorted piece of burlap for the netting pattern, added clear glass and applied scraps, stringers, and larger coarse frit.
This Schnauzer dog is inspired by Murphy. I simply moved the loose frit around the glass base until it shaped up to a very painterly illustrated dog and added the specks, stringers, and confetti triangles to resemble the sometimes delicious bits of things he finds very irrestistable. I found this technique to be so simple, yet requiring persistent patience and experimentation with tools like a needle pointed mini awl, toothpicks, and varying dry paintbrushes.
Goldfish, screened pattern base and fish for the top layer with scrap Bullseye color and bits of orange stringers.
First day using a little of everything-frit( periwinkle), stringers (thin lines), and scrap bullseye in orange and irridescent on one clear glass base. 
My example of wafers ( berries and holly leaf) add to base for second firing with confetti glass that melted more like wet tissue than the original hard edged form.
Experimented with mixing liquid and black frit to apply from a squeez bottle for dots and linear design. I also cut paper stencils for the silhouette and used a strainer to dust frit for airbrushed look. Look closely for bubbles possibly caused by the liquid trapped between the two layers of glass.
