Interesting. The opaque yellow in 'old' handmades is a Naples Yellow or lead antimonate yellow. Other possible opacifiers include lead arsenate and calcium phosphate / bone ash. The transparent red used in 'old' handmades is gold ruby. Think red stripes on peppermint swirls. The gold based color pallet is so distinct compared to selenium and copper.

Could be a chord used to hold the child in the chair. They are quite squirmy at this age...lol
Here's my fave vintage marble photo....

Not sure why the pic went away...here it is again :-)

The Greiner page was one of my better pieces of marble scholarship.....
Duplicating the process in the glass shop is just as fun in my mind. Here is my current colour in the furnace. I am not making marbles but am instead blowing some killer vases and bowls out of this oxblood.

I found a tiny non-seamed marble at MFC that was smaller than 1cm.

Reminds me of some other marbles on ebay currently......

Those are nice. The pink colored ones are extra hard to find.

Made a few 2" oxbloods...enjoy.

Nice American Cornelian marble.
Red slags (Akro red slags, Cerise agates, etc) were colored with selenium - true 'oxblood' glass as known from MFC and Akro is made from copper - there is no continuum between the two. Copper ruby requires very specific heat treatment to develop the color on a predictable basis.

Just sold one on ebay and it was signed.

Looks torch boiled to my eyes. Probably when the punty rod was removed to smooth the pontil down. This area also exhibits further 'striking' or a differing level of opalescence development / opacifier particle size / concentration.

....this is one of my new creations. I was just looking for an unbiased opinion of my work. It was indeed cane-cut. That's the rest of the story :-)

I have some just like this from the Navarre plant as well as Barberton.

Looks like a normal Ohio made melted pontil marble to me.

Here's what I found at J.E. Albright....

Not sure what to call this type. SIze is about 1.5". Core is transparent blue and looks lobed form the ends. Has a bit of mica. Pontil is ground.

MIlton Bradley Co. sold one just like that called "The Down and Out Marble Game". It can be found in old catalog advertisements.
