The tutorial for simple handmade clay desserts is as follows:

Preparation materials: various colored clays, iron sheets, small plates, paints, scissors, and iron picks.

1. First, pinch out small balls of various colors, as shown in the picture.

2. Flatten one of the small balls, as shown in the picture.

3. After flattening, cut a slit with an iron sheet.

4. Then put it on a small plate.

5. Use the same method to process all the small balls, and then press them slightly with your fingers.

6. Then apply white paint.

7. Roll a piece of white clay into a long strip, and then cut it short with scissors.

8. Put the white clay on the prepared snacks.

9. Completed.

Clay is made of a plastic aluminum silicate salt that can be very small. The materials contained in it are iron, potassium, calcium, magnesium, and sodium. Clay is mainly formed by the weathering of silicate minerals on the earth's surface. Clay types are classified into three categories: geological origin classification, high temperature resistance, impurity classification, and customary classification.

It is divided into primary clay and secondary clay. Primary clay is a kind of residue after the weathering of the parent rock, so the particles are relatively coarse, the temperature required for sintering is high, and the plasticity is poor. Secondary clay is clay transported to rivers and swamps by rivers. It has fine particles, many impurities, low firing temperature and strong plasticity. It can be divided into kaolin, clay, barren clay and shale.

Kaolin is mainly used to make ceramics and refractory materials, with coarse particles and no impurities. Clay soil is secondary clay with finer particles, good plasticity and more impurities. Barren soil is a hard clay that does not loosen when exposed to water and has poor plasticity. Shale has the same properties as barren clay, but has more impurities.
