Abstract
An inert chemical material comprising primarily paraffin or wax is deposited on a surface of a plurality of sheets of glass and the sheets stacked with the deposited paraffin or wax forming intercalations therebetween. The paraffin or wax material may be deposited in granular or molten form. Advantageously molten material is deposited in spaced drops to form spaced raised spots over the surface of each sheet. Preferred dimensions, melting temperatures, compositions, etc. are given. A first group of spots may be initially deposited of paraffin or wax material having a lower solidification temperature, and thereafter drops having a higher solidification temperature deposited thereon. Apparatus for performing the methods includes one or more heated reservoirs positioned over a conveyor and having a group of nozzles spaced laterally of a sheet of glass on the conveyor and actuated to deposit molten paraffin or wax material drop by drop on the surface of the glass sheet.
