The Blue Firmament (which means the top of it).
Blue, the colour of calmness and serenity, has been used for centuries to represent the sky, sea, and deities residing over them. It promotes tranquility, mental relaxation, and a sense of fulfillment. The shade is also associated with intelligence, as it’s been proven that the color blue gives mental clarity, stimulates thinking, and improves concentration. I do hope 'Oldwin' can helps you with this.
I've used my artistic license with a blue ram, because I just loved this coloured glaze. The colour blue has a lovely meaning as you've read above, so I thought I'd combine them both.
The original reference was taken from a friends ram, which lives on her smallholding in Rudston, Driffield.
