DIY Clay Heart: Step-by-Step Craft Guide

Materials

• Red air-dry clay or polymer clay
• Sculpting tools (toothpick, knife, silicone shapers) or household items
• Work surface (wax paper, silicone mat, cardboard)
• Water (for air-dry clay smoothing)
• Acrylic paint/sealant (optional, for decoration)

Steps

1. Condition Clay: Knead until soft, pliable, bubble-free.
2. Form Base Shape: Roll ball; shape into heart (two rounded tops, pointed bottom). Use reference image.
3. Add Anatomic Details (Optional): Use tools to carve chambers (right/left atrium/ventricle), aorta, pulmonary artery, vena cavae, coronary vessels.
4. Refine Surface: Smooth with damp finger/brush; add texture if desired.
5. Dry/Cure:
   • Air-dry: 24–72 hrs depending on thickness/humidity. Rotate for even drying.
   • Polymer clay: Bake per package (typically 275°F/135°C, 15–30 min per ¼").
6. Finish: Paint (anatomically accurate or artistic), seal with clear acrylic spray.

Tips

• Work in sections; keep unused clay covered.
• Support arches with foil armature if large.
