The brown clay pigment can withstand temperatures up to 1280° Celsius. Some ...

Manganese dioxide - Wikipedia

Manganese dioxide also catalyses the decomposition of hydrogen peroxide to oxygen and water: 2 H 2 O 2 → 2 H 2 O + O 2. Manganese dioxide decomposes above about 530 °C to manganese(III) oxide and oxygen. At temperatures close to 1000 °C, the mixed-valence compound Mn 3 O 4 forms. Higher temperatures give MnO. Hot concentrated sulfuric acid reduces the MnO 2 to manganese(II) sulfate: …
