MODELING-CLAY MARVELS MADE BY SEVENTH GRADERS. REGULAR CUPS TURNED INTO MAGIC STAINED GLASS.

On February 16th, 2018 Ms. Beata Radzikowska, an interior designer and art fan, ran an artistic workshops for seventh graders.  A well-known but often underestimated modeling clay was a major medium of the workshops.

Modeling clay is a dough made from petroleum jelly mixed with calcium carbonate, chalk mixed with fatty acid (most commonly stearics) used for [multidimensional] modeling. The dough becomes shapeable in a temperature similar to human body temperature whilst in room temperature it loses its flexibility, however never hardens for good.

The advantages of modeling clay are the following:

  • it is reusable
  • it doesn’t dry out
  • it is non-toxic
  • it is dirt-resistant

It requires to be slightly warmed-up in hands by rubbing it or by placing in a bowl of warm water before use.

Modeling clay was discovered by a pharmacist Franz Kolbe in 1880.  The other alleged inventor of modeling clay is an Englishman, William Hartbutt, a sculpture tutor, who was trying to devise  a material which would have similar qualities to clay and be reusable.

Modeling clay is commonly used for:

  • educational games
  • minor repairs such as sealing

Seventh graders used modeling clay to decorate cups. Five different colors of modeling clay were combined together in a form of roulade, which was later sliced into very thin pieces and attached to the cup. As such the effect of colorful mosaic was obtained.
