Die verwendete gebrannte Magnesia kann gebrannter natürlicher Magnesit, wie gebrannter natürlicher Magnesit von Österreich oder Griechenland, oder gebranntes Magnesiumhydrat bzw. Magnesiumhydroxyd, das aus Seewasser, Solen oder Ablaugen erhalten wird, sein.
Eine typische Analyse von gebrannter Magnesia, die aus österreichischem Magnesit erhalten wird, ist die folgende :

The burnt magnesia used can be burnt natural magnesite, such as burnt natural magnesite from Austria or Greece, or burnt magnesium hydrate or magnesium hydroxide, which is obtained from seawater, brine or waste liquor.
A typical analysis of burnt magnesia obtained from Austrian magnesite is as follows:
