1 What is paper clay????

What do you do with it heating, paper clay is non-toxic, it is actually plasticine, but not as oily as plasticine, there are actually many colors, the market is mainly gray and white, you need to color yourself, it is best to use spray paint, in fact, toothpaste can also be made of clay, but poor quality toothpaste is easy to crack after drying, affecting the image of the scene, pigment can be used oil paint, you can also use model paint, as you like.

There are two types of paper clay: traditional paper clay and ultra-light paper clay. Ultra-light paper clay components include foaming powder, water, pulp, paste; The composition of traditional paper clay includes gum, fiber (and feldspar), etc.

The difference between clay and clay is:First, the reference is different.

1. Clay: a widely distributed colloidal matte and cohesive soil.

2. Clay: soil with few sand particles and clayey.

Second, the focus is different.

1. Clay: Clay is used in industry, model making, and art to make models.

2. Clay: Clay is formed by the weathering of silicate minerals on the earth's surface, and is generally weathered in situ.

Clays are generally formed by the weathering of silicate minerals on the earth's surface. Generally, weathered in situ, the particles are large and the composition is close to the original stone, which is called primary clay or primary clay. The composition of this clay is mainly silicon oxide and alumina, which is white and fire-resistant, and is the main raw material for the preparation of porcelain clay.

The clay continues to weather, becomes smaller, and then migrates through flowing water and wind, and forms a thick layer of clay downstream, called secondary clay or secondary clay. This clay is contaminated, contains more metal oxides, is dark in color and has low refractoriness. Because of its good viscosity and plasticity, it is the main raw material for the preparation of clay.

Paper clay is a kind of soft sculpture material popular in Europe, America, Japan, South Korea and other countries, because the raw material is mainly paper fiber, so we also call it pulp mud or paper clay.

Paper clay is lighter and has many advantages over flour clay. There are two types of paper clay: traditional paper clay and ultra-light paper clay. Ultralight paper clay components include foaming powder.

water, pulp and paste; The composition of traditional paper clay includes gum, fibers (and feldspar), etc.

Peculiarity. 1. A variety of colors, non-toxic, non-sticky, good softness, strong plasticity, 2. The work does not need to be baked, it is naturally air-dried, and there will be no cracks after drying.

3. After the work is dried and set, it can be colored (can be painted with watercolor or advertising color), and watercolor, oil paint, and acrylic can be used.

Pigments, nail polish.

etc., there is a high degree of inclusiveness. After the color is dry, it can be coated with varnish for long-term storage.

4. High degree of combination with other materials, whether it is paper, glass, metal, lace, or beads, it has an excellent degree of tightness.

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

Causes and classification of impurities:

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 a clay that is carried from rivers to rivers and swamps, with fine particles, many impurities, low firing temperature and strong plasticity.

High temperature resistance performance classification:

Divided into refractory clay, refractory clay and fusible clay, the refractory temperature of refractory clay can be as high as 1580. The other two can be greater than 1580 or less than 1580 and can be fired.

Customary classification: can be divided into kaolin, cohesive soil, barren clay and shale. Kaolin is mainly used to make ceramics and refractory materials, and the particles are coarse and free of impurities.

Cohesive soil is a secondary clay with fine particles, good plasticity and more impurities. Barren soil is a kind of clay that is hard and not loose when exposed to water and has poor plasticity. The performance of shale is the same as that of barren clay, but there are more impurities.
