The Terracotta Army of China

In Shi Huangdi’s Terracotta Army has large amounts of MgO. Modern Archeologists claim there is not a definitive process that they have found to how they made these so long ago. They come up with many clever ideas to how they could have “fired” these life size, partially solid ceramic figures, when the building industry in China is making kiln free ceramics now. Magnesium Oxide Sheeting!

The Great Wall of China

MgO based mortar, and soil brick stabilizer, is used extensively on The Wall, and in many places, has outperformed, and outlived even some stone. The “Great White Mountains” that “The Wall” follows, are said to contain enough MgO to replace all of the Drywall and Plywood, on the planet, at the current consumption rate, for 800 years.

The Pantheon

The “pozzolana” they used for the cement in many Roman buildings contain large amounts of MgO and other Metal Oxides. A main source for raw material was, of course; Magnesia, Rome. There the volcanoes had been “cooking it down” for them, much the same as we do in kilns today.

Modern Discovery

In 1618 a farmer at Epsom in England attempted to give his cows water from a well. This they refused to drink because of the water's bitter taste. However the farmer noticed that the water seemed to heal scratches and rashes. The fame of Epsom salts spread. Eventually they were recognized to be magnesium sulphate, MgSO4. Black recognized magnesium as an element in 1755. It was isolated by Davy in 1808 who electrolyzed a mixture of magnesia (magnesium oxide, MgO) and mercuric oxide (HgO). Davy's first suggestion for a name was magnium but the name magnesium is now used.

The base of the Brooklyn Bridge is made from a locally mined cement called, “Rosendale Natural Cement”, that is CaO and a little MgO. The only natural, non-fired cement, made in the USA. Terrazzo Floors of the 18th and 19th century are MgO based cements with decorative aggregate, ground and polished.

Current Uses

Taipei 101, Currently the tallest building in the world. All 101 stories use our exact brand of MgO sheeting on the inside and outside of all the walls, fireproofing beams and as the subfloor sheathing

MgO Sheeting is the “official” specified construction material of the 2008 World Olympics buildings. A project costing over 160 billion dollars. Over 8 million square feet of MgO Sheeting is installed.
It is now estimated that over 2,000 companies are manufacturing MgO Sheeting worldwide.
