Industrial Waste Materials

Chemical analyses of some of the waste materials I use
to colour many of my glazes.


QIT Red Dust :

QIT stands for Quebec Iron and Titanium. QIT owns an ilmenite mine in northeastern Quebec.
The ore is shipped to Tracy where it is processed into titanium dioxide slags, iron, steel billets
and steel autoparts. This dust comes from the dust collecting system of the steelmelting department
and has the following general formula:

FE2O3 85%
SIO2 5.0%
CAO 5.0%
MGO 1.0%
ZNO 2.0%
CARBON 2.0%
TOTAL 100%

It was 170 mesh sieved.

A theoritical substitution is as follows for each 1% of the stuff :

Red Iron Oxide 0.820
Silica 0.050
Whiting 0.060
Dolomite 0.050
Zinc oxide 0.020
Total 1.000

Atlas Brown Dust :

Atlas Stainless Steels is a maker of stainless products and owns a plant in Tracy, Québec where
sheets of stainless steels are rolled. This brown dust comes from the anti-pollution system of the
melting department and has the following general formula:

FE2O3 58%
CR2O3 14%
NIO 5.0%
MNO 7.0%
CAO 7.0%
MGO 6.0%
SIO2 3.0%
TOTAL 100%

This waste material was 170 mesh sieved.

A theoritical substitution is as follows for each 1% of the stuff :

Red Iron Oxide 0.702
Green Chromium Oxide 0.161
Black Nickel Oxide 0.031
Manganese Dioxide 0.046
Dolomite 0.092
Silica 0.014
Totals 1.046
