Do not use unbaked clay on unprotected furniture or finished surfaces.  Start with clean hands and work surface area. Good work surfaces include wax paper, metal baking sheet, or disposable foil. Knead clay until soft and smooth. For best results, clean your hands in between colors. Shape clay, pressing pieces together firmly.  Bake on oven-proof glass or metal surface at 275 °F (130 °C) for 15 minutes per 1/4” (6 mm) thickness.  For best baking results, use an oven thermometer. DO NOT USE MICROWAVE OVEN. DO NOT EXCEED THE ABOVE TEMPERATURE OR RECOMMENDED BAKING TIME. Wash hands after use.  Baking should be completed by an adult.

Begin by preheating oven to 275 °F (130 °C). Test temperature with oven thermometer for perfectly cured clay. For best results, condition all clay by running it through the clay dedicated pasta machine several passes on the widest setting. Fold the clay in half after each pass and insert the fold side into the rollers first. 

Condition a small amount of Yellow Translucent clay, about ¼” thick and ¾” square.  Add to this a bit of Ultramarine Blue, approximately a ¼” diameter ball. 

Blend the two colors until completely mixed.

Form the jade color clay into a ball large enough to fit into the ring blank. You want the clay to be rounded in a dome shape on top when pushed into the blank. Shape as smooth as possible.

Press the crystal into the center with even downward pressure until the desired look is achieved.

Bake according to the manufactures instructions.
