These are comments found in Bob's recent white slag thread.
Please elaborate on the appropriate usage of the term "onyx" in connection with slags. (I understand it is also the name of an Akro corkscrew.)
Okay ... when I went to double check on the usage of "onyx" in connection with corks, I stumbled onto a partial answer to my question. In addition to confirmation that Onyx was an official corkscrew name, the Akro page at Marblealan.com says this about slags:
(i.e., except in a couple of special cases, Akro Agate slags would have been known as onyxes in their day?)
Next on the MFC page I found this:
And on the Peltier page:
The other reference I find to "onyx" at MarbleAlan.com is on the non-glass handmade marbles page:
(so the white bands on the natural onyx marble are the inspiration for the name "onyx" in connection with slags?)
Now, when I thought I almost had it figured out, I'm not finding any reference to "onyx" on Marblelan's CAC page.
What did Christensen call their slags?
Is it known/believed that with a few exceptions such as the Cardinal Reds noted above, the common name for all slags in the early 1900's would have been "onyx"?
If so, was the name supplanted in the minds of the populace by Akro's usage of it in connection with their corkscrews? Or is it your feeling that the shift occurred later?
Thank you very much!
