ive been meaning to post pictures of this example to this thread. this shows , at least to me exactly why we see these crescent imperfections in these bottles. it is clearly a mold pinch. this one just didn't get turned before the final blow.

Exactly! Some of us have been trying to get this point across for awhile now. This shape will always naturally occur because the parison becomes globular in shape when expanded by air. The outer edge is curved while the inner side is straight from the mold's edge.

I tried to change this to something like "half leaf pinch mark" but a wise ass reverted it back, I don't feel like changing 8 pages of titles but if anyone want's to start a new thread, I'm good with that.

Well everyone, I have now got two bottles that show the mark and both of then have convinced me that the marks came from a pinch. The direction of this one posted by twowheelfan, is similar to one I have to feel was a laid down pinch.

It doesn't explain the clothe like texture inside the half leafs - but I don't feel there is a good explanation for that. So all I cans say is, the straight side looked like what we would get from the end of a vertical milling cutter or the edge of a round milling cutter.

I was am always studying the marks made on early hand made bottles. So it caused a lot of participation - good or bad. I am sorry about that. So it won't hurt to eliminate the thread. RED Matthews

I forgot I had this bottle! I have had this bottle for a long time and never understood why there was confusion to why these crescents exist. I dug this bottle four or five years ago and since it has always been clear to me why, never even considered other options. im sorry I forgot I had it. should have posted it years ago. its not one I have on display so it was lost.
