There is plenty of misinformation found using google - something I thought we who conduct in-depth research would know by now. Your short quotes are incomplete information and incorrect - Canary glass is not the same thing as the more modern blanket term "Vaseline glass." None the less I digress to say again your marble has nothing to do with authentic Canary glass. As far as your Golden Onyx Oxblood marble being a rare, documented and purposeful Akro product - I see no evidence of that. You as the owner are free to call your possessions anything you wish, but it doesn't make it so in the rest of the world. I was able to copy a partial and correct explanation of the Canary/Flint/Lime/Vaseline research article shown below. Do with this information as you wish. Sorry for the sizing and order which is backwards , but this site has the weirdest upload system.
