Work at a glass bottle factory here..
That right there is a defect called a wedged base. It is caused by heat distribution issues in the process of making a glass bottle or container. Therefore if one side of the glass container is hotter, the glass will flow down more freely to the bottom of the bottle compared to the other side.
A defect like that isn't really all that much of an issue because it can't cause any harm and that's why it's out in the marketplace. It is a visual defect which should be addressed, but no need to throw it out.
Hope I helped here

Or it's a one-time fluke.
That's not designed, that's a manufacturing flaw.
Well, TiL my bottle is a dud. :| Interesting responses though. I guess it's true what they say. The quickest way to find an answer on the internet is to post something incorrect.
"What ya got here" would also work.
This is why I love reddit. There's always that one guy who's like "actually, I'm currently writing my master's thesis on this exact thing".
Watch yo profamity
Because people like me at a condiments plant are in control of X-ray machines that weed out jars that have loose glass, aluminum, stainless steel, and other hazardous contaminants. Trust me we get plenty of broken glass inside of glass jars.
It's a happy accident that takes places with regularity. Because of the way glass molding machines work they don't need to control the tolerance on that face. *former tool and die maker
I question the structural integrity of that bottle.
To borrow from software development: "It's not a bug, it's a feature."
You should work in marketing
Think about all the glass bottles, jars, cups, etc. you've utilized. How many times has a shard entered your throat?
The failure rate is acceptably low enough, and the factories have high enough standards
You mean accidentally formed? That’s cause by air pressure deforming the glass gob into the bottom of the parison mold.
A bottle will go through two manufacturers on its way to a customer. Each production plant should have inspectors to looks for such defects.
Also, bottles are packed with their neck to the bottom of the box, so if a chip were in there gravity would eventually leave it in the box.
Also, while it would be nice to consolidate at the bottom, what little left assuming the stuff won't stick to the walls, are gonna have to make their way back up and out as you invert the bottle.
Hey with so many millions of glass containers being made and sold every year, how do you ensure that some of them aren't slightly chipped and the chip later falling off and into the sauce or drink and stuff? How is it that we can just trust all these glass containers to hold up just fine?
Yeah, or it's Big Sauce trying to squeeze the last drops of PROFIT out of every bottle by giving you less than you bargained for with their conservative design. Wake up, Sheeple
I DID NOT HAVE SEXUAL RELATIONS WITH THAT BOTTLE.
I don't think anyone is suggesting we shouldn't trust glass jars. The question is how do they get such a high quality level, and the answer is pretty interesting, IMO. Good job, Reddit.
Thank you Mr. X-ray.
Right, I'm sorry.
Fine, fine, mouse, fine, rat, mouse, fine, syringe, fine...
Well, typically mass-produced stuff won't be that nicely designed but some super high-end type with that hydrophobic coating inside. Idk put a bunch of tabs in there, so a few drops and you'll be tripping for 6 hours. So yeah, I'd love a design that gets every drop in that sense.
I work at a bottle painting factory and can confirm.
Every bottle has their own unique slope, if it affects the volume of the bottle it will be pulled on this guys end. ^
It is much more drastic on ware coming from China in my experience.
This actually is a major concern in the glass industry. Just last year Corona had a massive recall because some of the bottles they purchased had a defect called wire edge on their sealing surface--it's basically a line of extra glass on the top. Either during filling or capping, this extra bit of glass can get broken off and sit in the bottom of your beer, or it can remain partially in tact through the filling process and give you a good cut when your lip finds it.
Because these are expensive and dangerous defects that are well-known, most plants have inspection machines to kick these bad bottles off the production line before they even get close to packaging. I actually work for a company that designs glass container inspection machines. It's some damn cool stuff!
