Koala Ltd Run is described as "an opaque neutral grey"
Testers reported "Koala melted well in a moderate flame with no issues. You can see that the end of the rod has rings of colour ... suggesting it may be a striker, but the beads I made all came out a consistent colour [maybe something to bear in mind if you work it longer in the flame or even the soak time in the kiln perhaps?] It's a beautiful soft grey that sits between Effetre 268 and 248"
