Ochre is clay-colored with hydrated iron oxide. The famous “Terra di Siena” is a hydrated iron oxide from Tuscany. It contains silicates and aluminates that increase the transparency of the pigment. When limonite is heated through calcination, the water content is eliminated, resulting in the red hematite known as “Burnt Sienna.”

Thermite Reaction: aluminum reacts with iron(III) oxide

The reaction of iron (III) oxide and aluminum is initiated by heat released from a small amount "starter mixture". This reaction is an oxidation-reduction reaction, a single replacement reaction, producing great quantities of heat (flame and sparks) and a stream of molten iron and aluminum oxide which pours out of a hole in the bottom of the pot into sand.
