Ancient Roman Wax-Casting Intaglio Seal Stamp

45 mins Ages 7-9 Indoor

An engaging, screen-free learning activity that builds real-world creativity and critical thinking for kids aged 7 to 9.

Materials Needed

  • • Sealing wax stick or standard wax candle (1 unit)
  • • Wooden dowel or baked clay stamp block (1 unit)
  • • Toothpick or metal carving stylus (1 unit)
  • • Paper envelope or folded letter (1 unit)

Pro Tips

  • → Carve a design into the flat end of a wooden dowel or firm clay block using a toothpick.
  • → The carved design must be reversed (mirror image) if letters or numbers are included.
  • → Drip melted wax onto an envelope and press the stamp firmly into the pool: the carving transfers as a raised relief seal.
