Hi All (and Happy New Year)

I am downsizing my paperweight collection..and may be listing my 1973 end of day Perthshire  weight...PP19
I was looking at it closely today..and paniced..thinking I saw a scratch..but it is really a line inside the weight..which runs across part of the top and is visible in cetain light and at an angle....(I REALLY tried to take a pic..but it is impossible so far to capture it--but I will continue to try!)

 If anyone knows what I am trying to describe   ;)  Is there a name for this?  Meanwhile back to trying to get a photo of it...
Thanks so much..

Striation?

Hi,

From your description, it could be some cording (these lines in the glass or cording occur during the encasement).

It is regarded by some as a flaw (it does not bother me much if it does not interfere with the design). I have never seen cording in a Perthshire weight before, though.

If the line looks shiny and reflective it may be a crack. We really need a picture

Hi Janette

It does sound like 'cording' / 'sugaring' / striations, whatever you wish to call it. Looking at your two images on Photobucket direct, if you mean the horizontal line curving down at the right, then it is cording.  Not common in Perthshire weights, but not unknown, especially in earlier ones.

Thanks so much Alan...yes...that is the line I was talking about...above my finger-- I sometimes see it in my cut glass pieces..and in some other weights I have..just never knew what to call it...and I always like to make my descriptions very accurate..!   
And for my own edification...what is the cause..?

Movement in the clear glass being used to make the casing, while still hot.
I call it striations.

It also could be an annealing crack , i hope not , you dont often see them in Perthshire weights so dont panick .
As Alan said you dont often get striation or any other flaws with Perthshire .
