Our Paper Clay Formula

We developed this paper clay as a replacement for two-part plumber’s epoxy, which is the standard for creating wire armature grab points as well as quick and easy props. It cures quickly from the inside out and dries incredibly hard, but it’s also toxic (and smelly). This clay dries from the outside in and takes anywhere from 1 to 3 days to dry. You can experiment with speeding up the drying process by placing it in the sun on a hot day, a drying cabinet, or using a blow dryer. Though for best results, giving it the time to dry naturally will result in the strongest clay.

Materials Needed

  • 6 pages of magazine paper cut into 1/2” strips
  • 2 cups of warm or hot water
  • 1/2 cup paper pulp
  • 1/4 cup sweet rice flour
  • 1/4 cup organic white flour
  • 1 t salt
  • Water, as needed
  • Small bowl
  • Mini chopper
  • Jar


  1. To make the paper pulp, combine the water and paper strips in a bowl and let soak until the water cools down. You can leave it overnight, but it’s not necessary.
  2. Once soaked, remove the paper strips from the bowl and place them into the mini chopper. Add a splash of the paper water and pulse until the strips break down into small bits. If the paper isn’t breaking down easily, add a little more water.
  3. Pour the remaining water into a jar and set aside.
  4. In the bowl, combine the paper pulp, sweet rice flour, and organic white flour. Mix with your hands, like mixing bread dough, until the ingredients form a smooth ball. Add water as needed.


  • Best if used immediately.
  • To store, place remaining clay into a compostable bag or cling wrap and keep in the fridge.
  • Over time, the clay will eventually begin to either dry or become moldy. This will differ depending on your location and exact conditions.
  • If you have leftover clay, break it up into pieces and compost it.
