what type of bottom would this be

[RED Matthews]

Hello all of you. I have found that soime molds were vented by a round hole drilled in the bottom of the mold and a dowel that was relieved by three flats on the sides of the length of it. When tapped into the hole it provided three air release vents in the circle. Just a thought from what I observed. Obviously that is an early and neat old bottle.

Reds on the mark considering the dimple I'd say, Bill if you look very closely I believe your going to see a mold line like I've shown below, making the mold an odd type of keyed hinge mold that was used on some mid western flask during and after the civil war period... I do not see evidence of a cup mold, and it would be a very early use of that type of mold...

There are definately cup molds used earlier than that but you are right they wouldnt be common on a flask like that. I can believe it just has an obscurred mold line.

So would you guess the bottom of the bottle was handeled while it was still very hot and soft causing the mold line to be obscurred . It does almost feel like a thumb print on one side of the bottom .Also was wondering what caused this crease in the sholder.Wanted to thank you all for your input too.

Ive seen a few bottles that had the mold lines practically erased, but normally this was from either being in a dump that was burnt, although it could of been reheated or the gather could of been too cool... If I hadn't seen similar mold lines I wouldn't of even guessed it, but there are molds that had a weird zig zag like that, if you look close you can see it in the pic... Ive always guessed they were from a re-worked mold, but that is just speculation...

the fold in the shoulder is probably from the glass catching in the mold and folding in on its self Bill, seems to happen every now and then on strap flasks in particular...

I think the guys in that video skipped the parison step..

Here is a picture of one of the ones I have. The molds are on the edges of the seams just like a typical diagonal hinge mold but no seams are visible on the base. It also has the circular vent mark in the center although it didn't photo real well.. All I have seen, including the amber ones have had this mark.
Jason has another one of mine he is cleaning maybe he can see if there are any mold marks on the base..Lobey, they date to the late 1860's.

Hello again dollarbill, I am looking at the picture of that mark on the shoulder rib. I can't decide from the picture if it is a nick that goes down in the rib, or just how the glass was moved. It looks to me like it is pushed in, and if so I think it was formed by a tool that slipped into the pliable glass when the finish glass was being applied. Obviously the bottle had to have been held with a snap case for the applied glass operation.

Doug, you have seen the mold mark I'm talking about right? It bothers me because I have a flask with the same exact mold line packed up but my collection is 150 miles awy right now!

can you get a glare shot with flash of your base? I doubt there was more then one mold for these bottles...
