No – The top surface of the finish is either ground down (most commonly seen on canning/fruit jars but also on screw thread finish liquor flasks, ink bottles, perfume, and other types less frequently) or the side mold seam stops or fades out distinctly below the top of the finish and usually – but not always – below the lowest portion of the finish (i.e., collar) as shown in the Question #1 picture above. (See the *Exceptions to help you Matter #dos box below for several significant exceptions to the side mold seam “rule.”)
The following is a dialogue quite preferred exclusions so you can the medial side mildew and mold seam “rule” discussing several brand of server-made package on which the fresh new straight front mold seams do not a little get to the most useful edge of the conclusion causing them to you can be seemingly mouth-blown.

1. Flame Refining – Even when not often discovered, machine-generated bottles might have flame shiny end up tires – a method which removed proof the latest neck-ring mildew and mold seam into the rim of the bottles. This type of bottle won’t have the medial side mold seam proceeding away from the upper finish front side over and you can onto the rim by itself. Fundamentally this is done to get rid of the mildew seam rim “bump” which had been often left by the prior to servers – an action that have aided helps most useful closing which have crown hats, screw-thread caps, or comparable closures and therefore sealed to your rim of your own become. These types of container often, but not, feel the straight front shape seam shifting as much as the actual the top find yourself front, not on the rim. They are going to supply other servers-generated services just like the demonstrated into Servers-generated Package page. In the connection with the website author, this type of machine-produced bottles try rarely encountered and you can most likely a function of early machine-produced products (1905 so you’re able to 1920s) which had reduced precise mildew fitting and you may lead to the need to have flame refining to help you facilitate right closing setting.
2. Milk Bottles – Many milk bottles made with press-and-blow machines from the very early 1900s into at least the 1940s resulted in vertical side mold seams that gradually fade out on the neck http://datingmentor.org/nl/datemyage-overzicht/ distinctly below the base of the finish. (Click here for a picture of a typical 1910s to 1940s milk bottle.) This exception to the side mold seam “rule” was caused by the specific workings of these machines which masked the upper portion of the side mold seam. These milk bottles will also virtually always have a diagnostic mold seam horizontally encircling the outside of the finish and a distinct valve/ejection mark on the base. Click on the image to the right to view both mold seam features pointed out on a press-and-blow machine manufactured milk bottle made by the Pacific Coast Glass Company (San Francisco, CA.) between 1924 and 1930. (For more information and images of typical milk bottles from that era, including a reason away from why along side it shape seams fade out towards the neck, go to the Food Bottles & Canning Jars typology page.)
