What are the bases of dating
Both seams are quite diagnostic of machine manufacture and are usually visible, though the seam at the top of the finish can be hard to see on some bottles - especially if the finish was fire polished.
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).
Feature #2 (mold seam diameter) is not as strongly diagnostic as the primary indicators as mouth-blown bottles sometimes can have very fine mold seams.
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.
“He’s so good, if he just varies like he has and he’s quick to the plate like he has been, he’ll pitch.
I really think it will take care of itself.”In his fourth season with the Cubs, Lester has addressed the throwing issue repeatedly.
That’s what Butterfield is calling the move he wants Lester to make on grounders, naming it after former Bulls stars Michael Jordan and Scottie Pippen.“In his words, just eliminate all tension and bounce it over there,” Lester said. Obviously it was not a good throw, but my sights were a little off on what we’ve been working on.“The ball kind of checked up. It goes down as a 1-3 or a 1-6 or a 1-4.“It’s like when you jam a guy and he hits a ball down right field. We’ll continue to work on it.”Lester began purposely bouncing some throws to first last year, but usually they were one-hoppers that Anthony Rizzo could dig out. With Rizz, probably the surprise wouldn’t have been there… We’ll get the sight line right.”Lester has never been efficient throwing to bases, dating to his high school days.
