  • Description

The fourth darkest of the six Glass Alchemy Cobalt colours, Cobalt-4, 514 was designed to provide artists with the ideal cobalt blue for small blown work and old skool surface work.

Working Tip: Work in neutral flame to avoid reduction (grey streaks)

Artist Description by Mike Shelbo:

"Cobalt 4 is a choice colour for applications that will be blown out thin or when the colour is all on the surface.
  This colour is still light enough to see through when the thickness of colour is 8mm or less. Over reduction with heavy propane flame will leave minor grey streaks but working with a neutral flame will prevent this from happening.
 This is a great colour to encase other colours with and pull into smaller cane. Try encasing Paparazzi with this colour and pull stringers out for a nice subtle tint. Use this technique over opaques and Crayon colours for a variety of new possibilities" - Mike Shelbo
