These translucent hearts and flowers catch the light like genuine stained or sea glass. Crafted from cornstarch, baking soda, water, and food coloring, this clay dough produces a smooth, frosted finish as it dries. These ornaments are ideal for displaying in sunlit windows, hanging as holiday accents, or stringing into decorative garlands.
Equipment
- Medium saucepan
- Wooden spoon or spatula
- Parchment paper (2 large sheets)
- Clean, damp kitchen towel
- Rolling pin
- Cookie cutters (Hearts / Flowers)
- Drinking straw or toothpick
- Ultra-fine (400-grit) sandpaper
Ingredients
- 1 cup cornstarch
- 1 cup baking soda
- ¾ cup filtered water
- Food coloring (gel or liquid, drops)
- Mod Podge or Acrylic spray (optional)
Instructions
- In a medium saucepan (off heat), whisk 1 cup cornstarch, 1 cup baking soda, and ¾ cup filtered water for 60 seconds until completely smooth and lump-free.
- Place saucepan over low heat and stir constantly with a wooden spoon or spatula. As the mixture reaches its thermal threshold, it will rapidly thicken into a dense paste and pull away from the walls into a cohesive ball. Remove from heat immediately.
- Scrape hot dough onto parchment paper. Cover loosely with a clean, damp kitchen towel and let rest for 10 to 15 minutes until safe to handle (the damp towel prevents a hard outer skin from forming).
- Divide dough into portions and knead a small drop of food coloring into each piece until uniform. Keep tints light and pastel-toned to maximize light diffusion.
- Place a colored dough ball between two sheets of parchment paper. Roll out evenly to a precise ¼-inch thickness.
- Press cookie cutters firmly into dough. Transfer cut shapes onto a fresh sheet of parchment paper. Use a drinking straw to punch a clean hanging hole near the top edge of each piece.
- Let ornaments air-dry in a well-ventilated room. Gently flip every piece over after 12 hours to allow equal evaporation from both sides and prevent curling or warping.
- Once hard and ceramic-like, gently sand any rough edges using ultra-fine (400-grit) sandpaper. Coat all surfaces with Mod Podge or clear acrylic craft spray to lock out atmospheric moisture. Thread with ribbon and display.
Notes
Creative Variations: Pressed Botanical Inlays: Place a tiny dried leaf or pressed flower on top of freshly cut dough and gently roll over it once with a rolling pin to embed it flush into the dough. As it dries, the flower is locked inside the translucent matrix. Gilded Stained-Glass Edges: Paint a thin metallic gold or silver leaf border along the outer edges of the fully dried, sealed ornaments for a stained-glass lead effect.
