J_Ding Posted June 29, 2016 Report Share Posted June 29, 2016 That's a nice one (well, you know....). This example show one that can reach around the marble like a ring...like a noose was put around much of the marble. No worries, it wasn't .

migbar Posted June 29, 2016 Report Share Posted June 29, 2016 Often, if the crease goes all the way around the equator of the marble, it is a double ingot marble, made of two smaller gobs. Link to comment Share on other sites More sharing options...

ann Posted June 29, 2016 Report Share Posted June 29, 2016 "Orange peel" surface texture . . . (I have this marble now, and in hand the orange peel is not nearly as noticeable) Link to comment Share on other sites More sharing options...

At first I thought it was a double ingot too, but it appears not to be one (the internal ribbons are not separated to either side of the mib).

J_Ding Posted June 29, 2016 Report Share Posted June 29, 2016 Here is an example of a double ingot discussed above, in this case an Akro oxblood. John Link to comment Share on other sites More sharing options...

JerryG Posted June 30, 2016 Report Share Posted June 30, 2016 More annealing fractures. This poor handmade Oxblood is covered with fractures. I treat it very gently. Link to comment Share on other sites More sharing options...
budwas Posted June 30, 2016 Report Share Posted June 30, 2016 Cold roll. I stand corrected but I liked it more before. Lol Link to comment Share on other sites More sharing options...
Steph Posted June 30, 2016 Author Report Share Posted June 30, 2016 Thank you, Bud! I was hoping that you would post that. The button-shaped spot is an interesting formation we do see from time to time. I don't remember it always being accompanied by twisting. Sorry it wasn't what you hoped.

budwas Posted July 1, 2016 Report Share Posted July 1, 2016 Nice! Is that a handmade roll or machine? Link to comment Share on other sites More sharing options...
budwas Posted July 1, 2016 Report Share Posted July 1, 2016 Dang, the more I look the surface texture appears to have been fire polished and that pontil, oh ya,, definitely handmade. Link to comment Share on other sites More sharing options...
budwas Posted July 1, 2016 Report Share Posted July 1, 2016 I had to come back for a third look see Istmmrbls. I can't tell from the one picture. Does that roll have only the one pontil or is it a end of pan? Link to comment Share on other sites More sharing options...

Steph Posted July 16, 2016 Author Report Share Posted July 16, 2016 A need as arisen of some more pics of the basic, simple cutlines that you can sometimes feel with your fingers but we know are just ordinary as-made spots and newbies think are maybe pontils. Anyone up for that? Link to comment Share on other sites More sharing options...
Steph Posted August 3, 2016 Author Report Share Posted August 3, 2016 One last chance .... to save me from having to dig out my marbles and come up with some cutline shots. Don't make me do this! Okay, that's my to-do list for tomorrow. Link to comment Share on other sites More sharing options...
budwas Posted August 3, 2016 Report Share Posted August 3, 2016 Another cold roll crease. Not sure what it is but the base glass Is transparent green with lots of bubbles so I'm going to say someone forgot the potatoes. Link to comment Share on other sites More sharing options...
Steph Posted August 3, 2016 Author Report Share Posted August 3, 2016 THAT is an example of a cutline. Yea! You got the ball rolling! It's a Peltier Rainbo. A nice specimen. Forgot the potatoes? That went *whoosh* over my head. Link to comment Share on other sites More sharing options...
