2. Hazard identification
This product is not classified as hazardous according to the DOT classification.
During the firing process a very stable chemical crystal grid structure is formed.
Tiles therefore are not considered as hazardous to health.
However, during activities like drilling, sawing and grinding of tiles dust is generated
containing crystalline silica. Inhalation of this type of dust is hazardous to health and
should be avoided.
3. Composition/information on ingredients
Tiles consist of a mixture of predominantly clay types and other naturally occurring
mineral substances.
After mixing with water and pressing of the tile the body is fired at very high
temperatures.
During the firing process very stable crystal grid structures are formed in which the
individual chemical elements are incorporated.
This also applies to the glazing layer.
Main constituents of ceramic tiles (body) are silicon oxide (60-70 %), aluminium oxide
(15-25 %) and small percentages of the metal oxides.
Main constituents of the glazing layer are silicon oxide (approx. 50 %), aluminium
oxide (approx. 10 %) and calcium oxide (approx. 10 %); furthermore the glazing layer
may contains small percentages of the metal oxides and may contain trace of metal
compounds.
