Sure – The bottle has embossing or visible vertical side mold seams somewhere Dayton hookup apps on the body between the heel and the base of the finish or lip. A bottle s but no embossing, but all embossed bottles were molded in some way and have mold seams even if they are not readily apparent.

Often the vertical side mold seams are evidenced by very faint changes in glass density in lines where one would expect mold seams to be.
