Textile, Stone, and Ceramic Materials: Properties and Uses

Textile Fibers

Natural raw materials are extracted from plants, animals, or minerals.

Vegetable Origin

• Cotton: Comes from the fruit of the Malvaceae plant family.
• Linen: Obtained from the stem of the Linaceae plant family.
• Esparto: Extracted from the leaf of an herbaceous plant.

Animal Origin

• Wool: Produced from sheep hair; its natural color can be white, black, gray, or yellow.
• Silk: A liquid substance secreted by certain caterpillars, which solidifies on contact with air.

Mineral and Synthetic Origin

• Asbestos: A fibrous mineral structure used in the manufacture of flame-resistant fabrics.
• Metals: Used for lint in costumes, lighting, and religious worship.
• Synthetic Fibers: Plastic materials characterized by their great length, strength, and impermeability.

Stone Materials

Stone materials are obtained from rocks found in nature as large blocks and slabs extracted from quarries.

Natural Stone

• Marble and Granite: Rocks characterized by high density, a cold and harsh touch, and great strength.
• Slate: A hard, dense, and compact material that is waterproof, often used for roofs and pavements.

Binders

• Gypsum: Obtained from gypsum rock that is ground and cooked to dehydration. It is a soluble, adhesive material used for roofs, walls, and building coatings.
• Cement: Obtained from a crushed and boiled mixture of limestone and clay, with added gypsum. It is used to manufacture mortar.
• Mortar: Consists of sand and cement; used as a binder for other building materials.
• Concrete: A mixture of gravel, sand, water, and cement that offers great resistance to compression.

Glass

Glass is a transparent, waterproof, and hard material that is soft to the touch but very brittle. It is resistant to environmental conditions and chemical agents, made from a mixture of quartz sand, soda, and lime.

Shaping Methods

• Blowing Machine: The material enters a hollow mold where compressed air is injected to fit the walls. Once cooled, the mold is opened to remove the object.
• Floating on a Tin Bath: Molten material is poured into a tank containing liquid tin. The glass distributes over the tin plate and is pushed by a roller system into an annealing oven to cool.
• Rolling: The melt is passed through an engraved or smooth laminating roller.

Ceramics

Ceramics are derived from clay. There are two main groups: thick and fine. Thick ceramics are characterized by being porous, unlike fine ceramics.
