Question 1

What safety precaution is critical when working with uncured liquid epoxy resin?

Accepted Answer

Wearing nitrile gloves and working in a well-ventilated area because uncured resin can cause skin sensitization and respiratory irritation

Answer

Uncured epoxy resin contains reactive chemicals that can cause contact dermatitis and sensitization with repeated skin exposure, and vapors should not be inhaled in enclosed spaces.

Question 2

What is the 'Skinner blend' technique in polymer clay?

Accepted Answer

A method of creating a smooth gradient between two colors by folding and rolling a triangular two-color sheet through a pasta machine repeatedly

Answer

Developed by Judith Skinner, this technique uses a pasta machine to fold and run a two-toned triangular piece repeatedly until the colors blend seamlessly into a gradient.

Question 3

What is a 'cane' in polymer clay?

Accepted Answer

A log of clay with a pattern running through its entire length, which can be sliced to reveal the pattern on each slice

Answer

A polymer clay cane is a constructed log in which a design—such as a bull's-eye, flower, or face—runs uniformly from end to end and appears on every cross-section slice.

Question 4

What is 'UV resin' and how does it differ from two-part epoxy resin?

Accepted Answer

UV resin is a single-component resin that cures quickly under ultraviolet light rather than through a chemical mixing reaction

Answer

UV resin cures in minutes when exposed to a UV lamp or direct sunlight and requires no mixing, making it ideal for small projects and repairs but less suitable for large thick pours.

Question 5

Why should you avoid baking polymer clay in a convection oven set above the manufacturer's recommended temperature?

Accepted Answer

Overheating causes polymer clay to burn, release toxic fumes, and become brittle or discolored

Answer

PVC-based polymer clay begins to degrade and release harmful chloride compounds above recommended temperatures, and the piece will darken, crack, or crumble.
