Of the four shades of cobalt blue Northstar produces, this ranks as the second lightest. NS001 is well suited for small blown work, as well as sculpture when a medium transparent blue is desired. NS001 Cobalt Blue can take a lot of heat and can be worked in a wide range of flame settings. Though the color is extremely intense, be sure to stay out of reducing flames to prevent any dulling or graying.

This color is awesome just saturated enough to be a nice dark cobalt color but not too saturated so you can work it hard and long and it won't get the gray streaks like the dark cobalt gets.... I keep a lot of this in the shop

Beautiful Blue!

I always keep an inventory of Northstar's Cobalt Blue on hand. I have used in many different applications and love the results. This color is not sensitive to the different types of flames and I have had wonderful results to include coil pot application. If you are searching for a beautiful blue, Cobalt Blue is one to try!

Backing Color


One of my favorite backing colors for pendants. Works real easy and always keeps its color as long as you use a neutral to oxy flame.

Northstar's cobalt


Very nice color to work with, very cooperative :)

Bulletproof color


Cobalt is made by nearly every color company, but Northstar firsts are great quality and ready to go after a light cleaning. Works easily and very forgiving for new lampworkers, a great way to add some color to a project. Also has good saturation so it can be encased or thinned down and still keep a nice blue intensity.



Classic never disappoints



The best classic Cobalt. Love using it worth fume work... won't let me give 5 stars or I would have.

Fume looks amazing!


I love how fume shows up on this cobalt! Reminds me of space!
