Abstract

Certain example embodiments relate to the use of a ceramic frit that dissolves an already-applied thin film coating (disposed via a physical vapor deposition (PVD) process such as sputtering, or other suitable process). In certain example embodiments, the ceramic frit is aggressive in chemically removing the coating on which it is disposed, e.g., when exposed to high temperatures. The frit advantageously fuses well with the glass, provides aesthetically desired colorations, and/or enables components (e.g., insulated glass (IG) unit spacers) to be reliably mounted thereon, in certain example embodiments. Associated coated articles, IG units, methods, etc., are also contemplated herein.
