Question

Prevent rusting by baking a mixture of silicates on iron at
high temperatures.

Answer 1

Explanation:

Rusting can be prevented by:

1. Galvanizing - iron metal is coated with zinc.

2. Enameling - the iron surface is baked with a mixture of silicates at a high temperature.

3. Coating with red lead oxide paint or tar on the iron surface.

4. Oils and grease coating on iron surface cuts off moist air and prevents rusting.
