Abstract
The invention provides a method and apparatus for treating articles with particulate material, for example for thermally toughening glass sheets. The particulate material consists of or contains permanently magnetized particles and is subjected to an electromagnetic field which travels linearly through the treatment space and is effective to sustain a dispersion of the particulate material in the treatment space. The article is contacted with that dispersion.
