Full text: The clouds break after the rain, and this color makes the future.
The original poem is two sentences, or it is not a poem, because it is an imperial edict. Legend has it that Song Huizong once had a dream that it would be fine after the rain. He liked the color of the sky after the rain in his dream very much, so he sent a message to the porcelain-burning craftsman: "The clouds break after the rain, and this color will make the future."
I don't know how many craftsmen were stumped by this imperial edict of Hui Zong. In the end, the craftsmen in Ruzhou were even better, and they burned the color of "the clouds broke after the rain". This poem is actually a compliment to Ru kiln porcelain.
Extended data:
In the Southern Song Dynasty, Hui Zhou's Qingbo Magazine said, "Burning in Ruyao Palace is forbidden, and agate powder is used as glaze." Ru kiln products have fine soil, hard fetal bones and moist glaze. The glaze contains agate powder, which produces special colors, such as egg white, azure, pink green, bean green and shrimp green. Shrimp green is often light yellow, and there are blue and sky blue.
In particular, sky blue is the most precious, pink is the best, sky blue is precious, and it has the reputation of "the rain has passed the sky." The glazed house is as thick as a pile of fat, such as jasper, and the buckle is as fragrant. The glaze has crab claw pattern, roe pattern and sesame flower.
The blue glaze color of Ruguan kiln is the main color. But under different illumination and different angles, the color will change differently. Ordinary experience, in bright light, the color will turn green and yellow, just like the golden sunshine on the clear blue sky after the rain. In the dim light, the color is blue and blue, like a clear lake.
The reason is that Ru Ci agate enters the glaze, resulting in different oblique slice angles, and bubbles with different sizes reflect light differently.
