After my post about "Earth" - I got an email from Viviane at Pferdediebin - telling me I was apparently on some other planet on Earth. ;-)
The upshot is - that THIS is the beautiful effect she gets from Earth.
She suggested that it was because she was using it larger and working quite hot - so I decided to take another run at it.
This is a clear core (because I just don't have much of the Earth - I didn't start with much, and I'm now running out! When it went into the kiln - I really thought I had it - beautiful streaky patterns. But coming out of the kiln - wow - it's really pretty - but not getting that turquoise and blue thing happening. I really did cook this - but admittedly - it is a thinnish layer of Earth.
So anyway - I'm going to keep trying with the Earth until I get the turquoise and blue thing figured out. And if you want to see more of Pferdediebin's beads and glass tests - she too blogs on her tests of colours - check out her blog at http://pferdediebin.blogspot.com/. If you don't happen to read German - then open the site in the Opera browser, and let it translate for you automatically. She also has some cool murrini for sale on etsy.
Anyway - I'm thinking from her photo of the heart that maybe a slightly reducing flame is in order - but I'm out of the glass - so it's off to Nortel for me to get more of this intriguing colour!
