  MATERIAL AND WORKSHOP PRACTICES What Is Clay? Made from worn volcanic ash, clays are soft mineral materials. Clay is the consequence of volcanic activity that has been exposed throughout time to a variety of physical and chemical environmental factors. Another way to describe it is as a finely grained, sticky, stiff earth that can be molded when wet and then dried and baked to create ceramics, bricks, and other items. The structure and composition of clays vary based on their origin. They originate from several sources, each of which has a distinct mineral makeup. Historical perspective of Clay work The earliest humans used clay to treat minor illnesses like food poisoning, aches and pains, infections, and mineral deficiencies back in the prehistoric era. They even started using clay for cosmetic and spa procedures. when stone was available for construction, it was difficult and time-consuming to craft. devouring. Conversely, clay was incredibly simple to combine and shape, and after

  MATERIAL AND WORKSHOP PRACTICES What Is Thermocol? Thermocol is a thermoplastic polymer of styrene that is capable of being molded into objects. This polymer material is formed from monomer  styrene. The polymerization of styrene monomer results in the formation of polystyrene. Polystyrene is a synthetic polymer known as thermocol. It is useful in thermal insulation. Thermocol Sheet Making Process Thermoforming is the procedure used to create the plates. During this procedure, a thermocol sheet with a plate-like shape is heated over a negative mold cavity. Positive pressure is applied via a plunger (positive mold). After then, the entire assembly is cooled. USES OF THERMOCOL It is a thermoplastic polymer of styrene which can be molded into objects. It is formed by the monomer styrene that results in the formation of polystyrene which is a synthetic polymer known as thermocol. It is used for thermal insulation. It is used to protect products like TVs, computers, glass products, etc. W

  MATERIAL AND WORKSHOP PRACTICES What is Aluminum ?  Aluminum is a silvery-white metal, the 13 element in the periodic table. One surprising fact about aluminum is that it's the most wide spread metal on Earth, making up more than 8% of the Earth's core mass. It's also the third most common chemical element on our planet after oxygen and silicon. Aluminum Sheet Making Process After employing carbon-based negative and positive cathodes in an electrolysis process, the alumina is transformed into a liquid condition and CO2 is produced. After that, this liquid aluminum is poured into various shapes to form sheet ingots or slabs, which are subsequently utilized to make aluminum sheets and plates. WHAT ARE 5 USES OF ALUMINUM Window frames.  Consumer electronics.  Household and industrial appliances.  Aircraft components.  Spacecraft components. Working with Aluminum  I had great experience working with aluminum sheet made a rose with help of it. First i was not using gloves so i

  MATERIAL AND WORKSHOP PRACTICES  What Is Wood? Wood is a versatile and natural material derived from the stems and branches of trees. It has been used by humans for various purposes for thousands of years. There are many different types of wood, each with its own unique properties. Hardwood, like oak and maple, is known for its durability and strength, while softwood, such as pine and cedar, is often used for construction and woodworking. USES OF WOOD Wood is used to produce a wide array of products, including plywood, particleboard, wood pulp for paper production, and engineered wood products like MDF (Medium-Density Fiberboard) Timber and Lumber • Timber is any type of wood that is suitable for use as wood pulp for papermaking or as building material at any point after it is removed from the tree. • In the wood production stage, lumber is the wood that has been processed into beams and planks.           Wood Manufacturing Transformation Process: Head Rig: The tree is sawed into pie

  MATERIAL AND WORKSHOP PRACTICES   POP (PLASTER OF PARIS A soft mixture of sand and cement and sometimes lime with water, for spreading on walls, celling, or other structures, to form a smooth hard surface when dried. what is the plaster of paris used for? It  is commonly  used to precast and hold parts of ornamental plaster work placed on celling. It is also used in medical treatment. SUPPLIS NEEDS Water Powder Container for mixing it Mold PROPERTIES OF PLASTER OF PARIS  Plaster of paris exhibits the following  properties   Plaster of paris is a white-colored powder, that forms crystals of gypsum when     mixed with water.   It expends slowly and slightly  upon setting. So it is highly fire-resistant.   It is easy to spread on any surface.   It does not cause cracking of surface.   It gives a decorative interior finish.  WORKING EXPERIENCE WITH POP  At first when i start working on pop block in the beginning i found it very difficult to work on it but after breaking 2  blocks of pop
