Feature #7 describes a couple glass related features that are quite consistent in machine-made bottles, but not diagnostic, i.e., mouth-blown bottles may sometimes have few/no bubbles in the glass and even thickness.

Be aware that bottles and jars made by early to mid-20th century press-and-blow machines do not usually have ghost seams, since the parison mold was usually one-piece, but will typically have a valve mark on the base (see #6 below). A suction scar is present on the base of Owens Automatic Bottle Machine produced bottles.(Mold seam thickness and how high it protrudes [height] is of only moderate use in telling a machine-made bottle from a mouth-blown bottle, though if a bottle fragment has a hair fine mold seam, it is highly likely to be from a machine-made bottle.) 3.There are at least two additional finish related mold seams - one at the top of the finish which encircles either the bore or sometimes the outside of the upper lip portion of the finish (sometimes of these seams are present) and a horizontal seam immediately below the finish which circles the extreme upper neck (called a "neck ring parting line").The offset is a function of the orientation of the parison relative to the two molds (parison and blow molds) used on the particular machine, or occasionally, to the hot parison "sticking" to the neck ring of the parison/blank mold when transferring to the blow mold (Ceramic Industry 19-15).There are also no horizontal tooling marks present on the finish and/or upper neck as would be observable on the finish of mouth-blown bottles.2.As an anatomist with a particular interest in pregnancy and development in the womb, examples of animal and human developmental abnormalities were important scientific and teaching tools.{{BLW2010 | title=The piglet with two bottoms | description={{en|This is an 18th century specimen, from the collection of William Hunter.

These are faint, somewhat wandering, hairline seams which if present (usually) are sporadically visible on the sides of machine-made bottles.

The ghost seams are caused by the parison mold parts and if visible enough will be "attached" to the vertical seams in the finish.

It requires the same level of respect, empathy, and love you should show anyone. Unlucky for me, at a few seconds old I had not gained enough of a mastery of the english language to protest his decision, so instead I probably soiled myself and fell asleep.3. I personally identify as pansexual, I have dated boys, girls, and others on the lovely gender spectrum.

If you have dated a human being before, then you already have everything you need to date a trans girl. I am really proud of my sexuality, and I believe being open like this makes the world a more exciting place to live.

On many early (very early 1900s into the 1920s) and occasional later (1930s and later) machine-made bottles the vertical body/neck and finish mold seams are discontinuous and offset from each other; click offset seams for a picture of this attribute.
