I have just ordered these new rare earth elements form Laguna Clay:
I was wondering if anyone has had any experience working with these oxides? From the article I read the colors look fabulous, shell pink, bright purple and vibrant yellow green. These are not stains. For more information:
This article includes some high fire recipes from David Peir.

I've been using them for over a year now. I fire to cone 10,
reduction- so the colors are not quite the same.
The pink is barely pink.
Neodymium gives very nice pale blues, different from cobalt colors.
I really like the green from praseodymium.
You do have to use higher levels of the oxides as colorants 6% - 8% is
common. The colors also merge nicly- at least the blue and the green.

Surely you must be firing this on a stoneware or a semi-porcelainous body.
Erbium fired on a grolleg porcelain is so pink it hurts the eyes. One could
hardly get much pinker!
All of the lanthanides are rather muted (as far as I can tell) on stoneware
bodies - Erbium looked rather dull and pale on BMIX.
They all look very bright on grolleg based porcelain bodies. On porcelain
you need to mute them or just use them as accent colours as they are
absolutly antiseptic used in a pedestrian transparent glaze.
Your mileage may vary....
