Paris Interiors

Plaster of Paris is an odorless powder consisting mainly or exclusively of calcium sulfate hemihydrate (CaSO4 aec 1/2H2O) and is generally non-toxic.

Although Plaster of Paris is non-toxic, however, ingestion of a sufficient quantity can lead to mechanical obstruction of the intestine, especially the pyloric region.

Where there is a danger in the dust: a prolonged and repeated exposure to the air of free respirable crystalline silica can cause lung disease (eg, silicosis)
and / or lung cancer. This is particularly true of the materials industry quality construction quality which may contain crystalline silica. Under normal "domestic" conditions, you are very unlikely to suffer ill use.

This is the plaster of Paris SHEET:

Well, plaster of Paris is a former pygment from French as its name indicates. Really, he was appointed French was beacause the country using the largest quantity of pygment. POP is a basic PYGMENT white lead carbonate, for example cerussite. Following a toxic IT?
Well, the results POP toxic by direct assimilation once it has been manufactured, for example, instead Pygment fresh paint old who do not.

Plaster of Paris, a jelly mass (plaster) with a white mud. However, artisans most effective in Europe are not old Dutchman, despite French, Netherlands, has learned that manufacturers HAD GOODS BETWEEN LEAD-IN wells filled with moisture and organic matter.
Thus, the activities of bacteria ferment organic materials and bacteria ASSURE THE STATUS searched:
-) Aerobic bacteria and air blows diminuta availability of oxygen;
-) Bacteria aerobic and anaerobic bacteria ferment slow organic controls;
- Give fermentation) off carbon dioxide saturating the pit.
deaerated conditions allow a late lead corrosion goods in its basic carbonate

2 Pb (s) + CO2 (g) + O2 (g) + H2O (aq) ---> Pb (OH) 2.PbCO3 (s)

which is based on POPs.

POPs had been involved in the phenomenon of Black Mary, for example, religious paintings, which became black.
Indeed, old candles from animal fat burning vapors leaving sulfur rich. Well, gas rich in sulfur react to form POP cons lead sulfide

---> 2 PbS (s) + CO2 (g) +3 H2O (aq)

its black color.

I hope this helps you.

At room temperature POP is non-toxic. But at high temperature generates toxic sulfur oxides (In extreme conditions, then do not worry). Since you use it for interior decoration, I see no problem in using it.
