Just bragging - what I bought today!

<< < (6/6)

Glen:
I've heard back from Howard Seufer (I showed him the photo of that green Four Flowers variant on eBay). He has written out very clearly for us what he believes the marks are.  I suspected the metal mould may have been hotter than the glass, but Howard has found evidence in the marks to determine that it was, in fact, cooler than the glass. He also asked Bob Hill (mould shop foreman at Fenton) for his thoughts, which I have also added in the text below.

I am indebted to Howard for his expertise and constant willingness to help.

From Howard:

--- Quote ---These lines appear to have rounded edges.   The long line through the pattern is apparently a LAP MARK.   This could have been caused by the gob hitting the edge of the mould, (cooling at that point) and then dropping into the mould; or be caused by the outside layers of the gather chilling too much before entering the mould.   The chilled outer surfaces lap on themselves and prevent the glass from completely filling against the side of the mould.
 
The other lines may have been (again) with the gatherer taking his time winding the glass and chilling the outer surfaces of the gob, while waiting for the presser to accept the glass.   The lines would be similar to the flow mark in the pattern area.
 
Another type of line that has rounded edges and goes into the glass is a TEAR (rhymes with"pear") or a crizzle (shallow crack) that have been healed by reheating the surface.   I believe this is the condition you refer to "make lines that can look a bit like fine cracks" - healed TEARS.
 
The photo isn't clear if the smaller lines are standing out from the surface or are down into the surface.   IF they are standing out, they could have been caused by damage to the mould by the end of the presser's shears scraping the iron while cutting the glass gob.  The mould iron is soft and the shears can dig into the surface.
 
The mould was slightly cool, less than 830 degrees F., because SETTLE WAVES can be seen in the pattern between the Lap Mark and the marie.   This mould was not "too hot".

--- Quote ---After talking with Bob Hill, former mould shop foreman, he agreed that the smaller lines were probably LAP MARKS also.   He said it looked like a piece that was made when the presser was using glass to warm up the mould and the glass was gathered just too cold.   The piece was one that should have been thrown away on the shop, he said.

My eternal thanks to Howard.

Della:

Thank you so much for taking the time to get the answers, Glen :hug: A huge thanks to Howard & Bob too.  :clap: :clap: It is fabulous to read things in simple, understandable terms (especially for a plonker like me!).

Ours too, and our eternal thanks to you, Glen!  :hug: You really are a treasure!  :hiclp: :clap:

josordoni:
wonderful Glen! thanks so much.

Now we just have to keep using the new terminology (well, new to eBay buyers  ;D) and get them used to it!

Quackers:
Glen, that is absolutely superb - thank you so much, and thank you Howard and Bob - the first-hand knowledge is invaluable :).

As Lynne says, just got to remember to use the right terms and try to persuade other to do so as well.
