Fish Fossil

Try the fish press technique to create a unique showpiece for your home.


  1. Wrap fish in foil and place the fish in the oven for about 30 minutes 325 degrees.
  2. Gently remove the fish from the skeleton, keeping the skeleton as complete as possible. Discard the fish.
  3. Prepare a clean, strong work surface (such as a large table or you can even use a clean floor).
  4. Open bag of clay and place on work surface. Pound clay onto surface to get rid of any bubbles. You can work in small amounts of clay if too heavy to handle.
  5. Use a rolling pin to help create a larger clay slab. (Tip: check size of kiln you plan on using to make sure slab will fit inside.)
  6. Use the trowel to smooth out the top surface of the clay body. At this point, you may see some bubbles. You must try to get rid of all bubbles, because bubbles may cause your clay piece to explode during firing. Use Sgraffito-Duster™ tool to cut slits through clay only where you see bubbles.
  7. Repeat process, pounding and kneading clay, then smoothing it out. When you don’t see any more bubbles, you can create your project. Keep the unused clay in a plastic bag for future use.
  8. Dip sponge in water and wipe over clay slab to create a smooth surface.
  9. Place and press skeleton into clay, then gently remove bones.
  10. Use Sgrafitto-Duster™ tool to carve in grasses detail.
  11. Use Fan Glaze brush to softly brush over carved areas to remove any loose clay particles.
  12. Squeeze out a small puddle of each EZ Stroke color onto separate area of foil. Use Fan brush to apply 1 coat of Neon Red over center of fish (recessed skeleton will remain white; do not press paint into skeleton). Referring to photo for color placement, fill in fish with Neon Blue, Neon Yellow, Neon Chartreuse and Neon Orange. Clean brush after each color. Use Black to create spots on fish above skeleton. Also paint in grasses and water (again, do not press paint into recessed grass).
  13. Squeeze a small dot of French Dimensions for fish eye.
  14. Cover with plastic bag, and let clay dry completely before firing.
  15. Bisque fire to shelf cone 04.
  16. To create look of water, use Fan Glaze brush to paint alternating wide bands with 3 coats each of Envision Clear and Satin Clear Glazes on front of piece. The alternating glossy and satin finishes will help create look of water after firing. Also apply 3 coats of Envision Clear to back of piece. Let dry after each coat.
  17. Use Round brush to spatter Satin Clear over entire slab. This creates a look of soft bubbles after firing.
  18. Glaze fire to shelf cone 06.
