(b) Titanium white

(c) White lead

(d) Red lead

The question was posed to me by my college director while I was bunking the class.

My question comes from Ingredients of an Oil Borne Paint topic in portion Painting, Varnishing, Distempering, etc of Construction & Building Materials

Answer 1

The correct answer is (c) White lead

For explanation: White lead possesses good bulk and is the most widely used base. It is dense, permanent and waterproof. It is not suitable for delicate work as lead becomes discoloured when exposed to the sulphur vapour. It is most suitable for wood surfaces and not used for iron surfaces as it does not afford protection against rusting.
