What are tong marks?
We have a very unique vertical tempering furnace. This type of furnace allows us to temper pieces as small as 1″ x 1″ in any glass that is 3/16″ or thicker- glass that other glass tempering companies won’t even touch! In a vertical tempering furnace, glass is hung vertically by tongs and run through the chambers of the furnace. Also, since we have our own furnace we’re working on most pieces from start to finish entirely in-house. Not waiting for someone else to do the work means we can get your order out the door very quickly. This style of tempering does result in the glass having small tong marks or indentations left from the tongs the glass was hung from. These “dimples” are not imperfections and in no way do they compromise the integrity of the glass. The glass is 100% fully tempered- the marks actually prove that the glass was in the furnace!
