Answer 2

The addition of iron oxide gave a greenish-blue tint to glazed pottery.

• Harappans used a range of mortars and cement, including charred limestone and gypsum, in their experiments.
• Faience is a man-made substance manufactured from finely crushed quartz that was covered with silica, may be fused with soda, and then glazed with copper oxide to give it a dazzling blue shine.
• Faience was then used to create a wide range of decorations and sculptures. Iron oxide gave glazed pottery a greenish-blue hue, whereas manganese oxide gave it a maroon hue.

The chemical formula of mercuric sulfide is HgS.
