Brandon Franks Posted February 12, 2020 Report Share Posted February 12, 2020 Okay so this is confusing the hell out of me because there are not that many articles about it. All recipes I have call for black nickel oxide. I don't have it, I have green and black is hard to get around me. However, The density of black is higher than green, but the oxide weight is higher in the green. So, say a recipe calls for 4% black, if I do 4% green, it should be almost equal, right? I had a straight conversion list for oxides, but it fell on my kiln and burned... karma for constantly rushing pots, I guess... https://digitalfire.com/4sight/material/nickel_oxide_green_1967.html https://digitalfire.com/4sight/material/nickel_oxide_black_1074.html Thanks, Brandon Link to comment Share on other sites More sharing options...
Min Posted February 12, 2020 Report Share Posted February 12, 2020 Just use the same amount of green nickel oxide as you would use black nickel oxide. If you use nickel carbonate then you need 1 1/2 times as much of that to equal either black or green nickel oxide. Link to comment Share on other sites More sharing options...

liambesaw Posted February 12, 2020 Report Share Posted February 12, 2020 I think it's more like 1 and a 1/3rd as much nickel carbonate. It's 64% NiO whereas black nickel oxide is 90% NiO. Could be wrong though. I've never even seen green nickel oxide but apparently it's 100% NiO Link to comment Share on other sites More sharing options...
glazenerd Posted February 13, 2020 Report Share Posted February 13, 2020 Brandon: Black nickel oxide is pure, and green is carbonated. Carbonated by US standards means 40% oxide with 60% fluff (carbo)ate. Link to comment Share on other sites More sharing options...

Nickel ii oxide is green and 100% NiO, nickel III is 90ish percent nio, nickel ii carbonate is around 64% nio Link to comment Share on other sites More sharing options...
Min Posted February 13, 2020 Report Share Posted February 13, 2020 I've got the molecular weight of nickel carb at 118.702 and the oxide at 74.693 so (after rounding) 74.7/118.7 = 0.63 So reverse that for subbing nickel carb for the oxide. It's my understanding that nickel oxide can be black or green dependent on the processing method. Link to comment Share on other sites More sharing options...

This may help as a resource in the future, You can often go to Glazy.org, select materials and type in NIO for Nickel. From there often the various forms will show up. From that point if something needs to be converted to an equivalent 100% form divide the 100% recipe requirement by the concentration percentage of the carbonate in this case gets the carbonate equivalent of the oxide. So 10 grams of the oxide would be equal to 10 / . 62930 or 15.89 g of the carbonate. Sorry, math challenged tonight! Can also be 10X 1.62930 (add a one to the concentration, not the LOI for those who don’t want to divide) Link to comment Share on other sites More sharing options...

Thanks a lot, Brandon @Brandon Franks Whoops, had to fix that! Use the corrected above. Post in a sec. Sorry forgot my math! The Glazy resource is handy so at least that’s something that won’t fall into the kiln . (hopefully) Link to comment Share on other sites More sharing options...
