The mix consistency of plaster should be:
-
Single Cream
-
Double Cream
-
Devon Cream
-
Clotted cream
Correct Answer
A. Double CreamExplanation
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.Rate this question:

Where would you position the anchorage nails?
-
Along mould length
-
Thickest part of mould
-
Against the side
-
Near rule
Correct Answer
A. Along mould lengthExplanation
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.Rate this question:

Which one of these is not part of a running mould?
-
Stock
-
Foot
-
Slipper
Correct Answer
A. FootExplanation
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.Rate this question:

When constructing a running mould, how long should the slipper always be?
-
One and a half times the length of the stock
-
One and a half times the length of the brace
-
Twice the length of the stock
Correct Answer
A. One and a half times the length of the stockExplanation
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.Rate this question:

What is the function of shellac?
-
A sealing agent
-
A bonding agent
-
A retarding agent
Correct Answer
A. A sealing agentExplanation
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.Rate this question:

What is the main ingredient of grease?
-
Casting plaster
-
Tallow
-
Shellac
Correct Answer
A. TallowExplanation
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.Rate this question:
