Topic: Anybody heard of skeleton molds?

[krsilber]

I read that thread a few days ago, found it in the archives.  I don't know about diatreta, but Lierke's evidence for Roman cameo being molded instead of blown didn't hold much weight with me.  I loved this comment for its articulate derision alone:  "Lierke's preposterous idea that they are made by squeezing hot glass through a colander-like mould of plaster is absolutely risible, like most of her impractical theories."  Excellent word, risible!

I've heard from the guy that has the vase with bosses.  He still has it, but not at home.  He's going to pick it up and get back to me.

Cathy B, where in Australia do you live?  I did my post-graduate research on the Atherton Tablelands, lived there on and off for a few years...and loved it!

Hi Kristi - I'm in the much maligned Canberra. It's a great place.

Hi,
 I discovered this interesting film showing glass blowing into a frame. The result certainly looks like lenses.
 To see the film go to the "Cafe "
 Regards Patrick.

Thanks, Patrick, cool video!  I couldn't get it to work from your blogspot, but went to British Pathe and viewed it.  The metal frames are the kind of thing I was talking about when I attempted to explain that different-sized open areas would result in different-sized bubbles ("...a glass object blown into a metal structure that become part of the finished piece.").  In the objects in the video, though, the glass would be of a fairly similar thickness throughout the piece, or thinner where openings were bigger, as others have pointed out.  The big mystery behind the bosses on the Steuben and Hawkes pieces is how they ended up a lot thicker than the rest (which I'm convinced they are).

Haven't heard back from the guy with the vase.  After Easter if I haven't heard anything I'll pester him again.

Cathy, I never made it to Canberra.  I've heard it's a very nice city, though!

I see you already got the book... never mind.  :spls:

Hi, I am still with the idea of 'Cast on bosses '.

Quite like it, I'd say!  Thanks, Adam, for posting that.  I think in the earlier version that I believe was used on these pieces, the fins were hinged at the bottom.  There were also arms that formed the bosses.

I wrote the vase owner again, still haven't heard back though.

Hi, Looks to me like a DIP mold for doing ribbing or optics................... Only a thought. Patrick
