Basic Fibrous Work - Running Mould

Tallow is the main ingredient of grease. Tallow is a rendered form of animal fat, typically from beef or mutton. It is commonly used in the production of grease due to its high melting point and lubricating properties. Tallow-based grease is often used in various industries, including automotive, manufacturing, and machinery, as it provides excellent lubrication and helps reduce friction between moving parts. Therefore, tallow is the correct answer as the main ingredient of grease.

Muffles are used to form a core.

Shellac is a natural resin that is commonly used as a sealing agent. It is applied to various surfaces to create a protective coating that seals and protects the material underneath. This coating helps to prevent moisture, dirt, and other contaminants from penetrating the surface, thereby preserving the integrity and appearance of the object. Additionally, shellac also provides a smooth and glossy finish, making it a popular choice for sealing wood, metal, and other materials.

A running mould is a piece of equipment used to form a moulding on the bench. It is a tool that is used to shape and create decorative patterns on wood or other materials. It is typically handheld and has a curved or rounded shape to allow for smooth and precise shaping of the moulding. The running mould is an essential tool for carpenters and woodworkers who need to create intricate and detailed mouldings for various projects.

Plaster of Paris is the correct answer because it is a versatile material that is commonly used for creating mouldings. It is easy to work with and has a quick drying time, making it ideal for moulding projects. Plaster of Paris also has good adhesion properties, allowing it to stick well to various surfaces. Additionally, it can be easily sanded and painted after drying, providing a smooth and finished look to the mouldings.

A running mold is a type of mold used in ceramics or pottery where the mold is opened and closed repeatedly to create multiple identical pieces. In this context, the "foot" refers to the base or bottom of the ceramic piece, which is not a separate part of the mold itself. The stock and slipper, on the other hand, are components of a running mold that help in the opening and closing of the mold. Therefore, the foot is not part of a running mold.

A splash brush would be used to apply plaster to a reverse mold. A splash brush is a type of brush with long bristles that are used to quickly and evenly apply plaster to a surface. This tool is specifically designed for applying plaster and would be the most suitable option for applying plaster to a reverse mold.

The slipper in a running mould should always be one and a half times the length of the stock. This ensures that there is enough space for the stock to move and rotate smoothly within the mould. Having the slipper slightly longer than the stock helps to prevent any jamming or binding during the casting process.

The correct answer is "Double Cream" because when mixing plaster, it should have a consistency similar to double cream. This means that it should be thick enough to hold its shape, but still be easily spreadable. If the plaster is too thin, it will be difficult to work with and may not adhere properly. On the other hand, if it is too thick, it will be hard to spread evenly and may result in a rough finish. Double cream consistency strikes the right balance between these two extremes, making it the ideal consistency for plaster.

The anchorage nails should be positioned along the length of the mould. This placement ensures that the nails provide maximum support and stability to the mould, preventing it from shifting or moving during the construction process. Placing the nails along the length of the mould distributes the anchorage evenly, making it more effective in holding the mould in place.
