Which of the following method(s) is obsolete for storing fragile patterns?

(b) They must be stored in wax plated shelves

(c) They must be stored in a wood wardrobe

(d) They must be stored in foam

This question was addressed to me by my college professor while I was bunking the class.

The question is from Finishing Patterns & Storing of Patterns in chapter Pattern and Pattern Making of Casting-Forming-Welding I

Answer 1

The correct choice is (d) They must be stored in foam

To explain: Foam has the ability to absorb shocks and sudden impacts to a very higher extent. Hence, Fragile patterns are stored while wrapped in foam.
