I own a few pieces of bone and most are uncut but was curious if someone knew if the more colorful cell patterns are from a different time period of being agatized, or are they from a larger species that maintained the colors better being that the bone was a thicker density? I find a lot of this black-carbon? type shown cabbed, but I am more interested in the last picture type of bone material and how it kept those colors. Any info would be grateful. Thanks.

That's some pretty dino bone, spiritstone. I don't have a clue, but I am pretty sure bhiatt can answer your questions.

The colors depend on which minerals are in solution at the time when cells are replaced. Different colors = different minerals in solution.

I can't see the pics, but I agree with the other -- minerals, minerals, minerals. The oxidation state also plays a role. Iron can make many different colors, for instance (red, yellow, orange, purple, red, brown...) depending on oxidation state and counter-ion(s). Things can be found in the same location, and have very different colors, such as these pieces of whale bone, both from Morgan Hill: www.flickr.com/photos/36618387@N06/9956123153/in/set-72157625698748877www.flickr.com/photos/36618387@N06/8002294363/in/album-72157625698748877/or dino bone, both from Utah: www.flickr.com/photos/36618387@N06/6348042012/in/set-72157625698748877www.flickr.com/photos/36618387@N06/6347295725/in/album-72157625698748877/-Enjoy, Stephan

The colors depend on which minerals are in solution at the time when cells are replaced. Different colors = different minerals in solution. if i understand this correctly, the quality of the bone cells being replaced are all depended on how much of a soup they were sitting in. Take for Instance the Utah bone compared to the Alberta bone as seen in the pics. The Utah is always so colorful compared to the Blacker looking bone from here, so if I am looking for this kinda of quality its best to continue with the Utah material and refrain from other localities. I was certainly thinking it had something to do with the density of the bone mass. Thanks for your assistance Don.

Not so much the soup, as the minerals dissolved in the soup. Many other conditions come into play as well. How long the original bone was in contact with the soup, depth the bone was buried, temperature and a whole bunch of other variables. To see some nice bone slices, visit this guys store & look through the pages. stores.ebay.com/The-Chiming-Rock?_rdc=1He's a bit on the high side price wise, but sells some really nice material.

Cool thread, I had wondered why my only slab of Canadian dino bone is so plain and lacking in fancy colors. Had kind of figured the dino bone in North America, being roughly the same age, would all be from similar colorful sedimentary formations. Never seen the Canada formations before and had not realized they were lacking the colors. I thought my slab was just a crappy example. Had not realized it was typical of Alberta bone.....Mel

I just collect pretty rocks. Different Minerals and impurities heat and pressure is about the extent that I know.

Groove wrapped that bone cab today. Not big on the two wire bail, so I wrapped the bail then silver soldered it to the inside for a tighter and stronger fit. Thanks.

That is beautiful! Did you post it in the wire-wrapping forum? What equipment did you use for soldering? Or how did you do the process?

I used my soldering gun and patience.
