Unobtainium - Northstar
Unobtainium is a very dense gun metal blue with lots of sparkle. It is well suited for stringer application and blown work. It is easily worked and can take a lot of heat. To keep the color most vibrant, work in a neutral to slightly oxidizing flame. Try to avoid deep encasement, it may cause cracking. Please use NS104 Unobtainium with care and test your application before making expensive pieces. Outside work seems to work just great with no problems. Try coating NS104 Unobtainium with NS086 Garnet or NS088 Pomegranate to achieve a brilliant ruby sparkle. Any transparent color coated over NS104 Unobtainium looks great.
Second quality glass can have the properties of odd quality glass, but may also have small stones, air bubbles, vary in tone/shade, or the shape can be very out of round. Both odd and second quality glass can provide a great value to the right person.

this is one of my favorite colors..I can't keep enough of it in the shop I use it as fast as I can buy it....works stiff but it's one of the most beautiful sparkly opaque blues I can abuse it and work it as long as I need and it always looks the same....takes tons of heat to melt this stuff down though

I really like this for a backing on marbles and pendants. I have had different batches though and sometimes it has looked more gray than metallic. Last few times I have gotten it the sparkle has been getting better and better. Perhaps the recipe is still evolving. I have not had any issues but I do not use it for inside or implosion work. I garage at 1000f and have not had any issues with garaging either but I normally save the work using this color for the second half of the day since it's recommended to keep garage times short also. Seems almost every custom piece I have been making lately the customer wanted this on it. Putting clear or transparent color over it is one of the things I love to do with it. Clear frit on top gives the effect of rain on metal. So sick.
Great for outer applications
Love this for outer work. Beautiful sparkled blue. Care needs to be given for deep encashment.
