The crack has to be drilled at both ends to relieve stress and prevent further traveling. You can dremel out the crack with a super fine dremel bit but it isn't worth the trouble. I have a milk with over 10 flash cracks in it and it never got any worse.

Would those tumble out or are they clear thru? Is there anything like resin or something, you could get try and get in that crack, really carefully-just for personal display-not to sell. That’s why I was playing with the windshield repair stuff, on some shot out bottles. It did ok, but your never getting it off! It has a feel of plastic and a temperature that is noticeable to most everyone here. Warmer than glass feels.

I recently gave this a try with no luck. I pulled a deep vacuum on a cracked milk bottle and it would not pull "windshield crack repair glue" through. Anyone have any other thoughts?

I was playing with that stuff! I’m glad in a way, others thought of that too. I just put it on a rag and used a wire to move it into the whole inside of the bottle. You could use slight temperature changes to expand and contract the glass and maybe work it into the crack? My luck, the crack would run, but that’s how we learn, right? But then I would wipe out that bottle so well, but for where u want it. You can do that until it’s just right , until you cure it? That’s the way I found! Additionally, I couldn’t believe how much dirt that I already thought was gone, came off the glass with that stuff.

Is there any way to repair cracks on this bottle? It's a rare bottle. The bottle itself is still intact, just cracks inside.

I'm not aware of a way to fix but the guys that repair Auto Windsheild Cracks may have a Method, I'm pretty sure they fix/fill small cracks but not sure about something that big. LEON.

That's a flash crack. Yikes. Never even crossed my mind to try and fix something like that. I hate flash cracks.

There is no way that I know of to repair cracks. The materials used on windshields are cosmetic and the ding is still visible. The repair is mainly to keep the windshield dings from further spidering across the glass.

One of the problem is the discoloration in the crack. Even if you use an optical epoxy you still need to remove the dirt. I use a fine dentist dremel bit to drill two micro holes thru the bottle just past the crack on both sides. This stops the crack from continuing while you open the crack up. Do not go thru the glass all the way just almost. Then I clean out the crack with acid. The rest is easy. Mix up the right color to match. This one is clear so no pigments are necessary. I have done a couple cracks. Your are pretty nasty. Especially the cracks that are angled in the glass. I use a fine tip conical bit. I use my hands to help keep the vibration down. Go slow. Cracks are the worst for making invisible partly due to the repair material being so crystal clear. I would enjoy this one until you dig an undamaged one.
