Abstract

A bed (2) of gas-fluidised particulate material is operated by extracting gas through ducts (7, 8) from a localised region of the bed so as to produce an unfluidised static condition of that region of the bed. The bed may be used for treating an article, for example thermally toughening a glass sheet which is lowered into the bed through the unfluidised region. The unfluidised particulate material may be sufficiently packed to obturate an opening communicating with the bed. <IMAGE>
