I've looked into sywq.cn, it, in particular, produces ceramic stones.
Could you clarify for not native speakers the difference between
ceramic (pottery),
porcelain,
glass (not that glass, that is in your window at home? (marbles)
), concerning the stones' material?As I noticed, the ceramic stones on sywq.cn are called "精瓷 fine porcelain" and "elegant porcelain" on Song Yun Taobao store. So, they must be synonyms.
In this forum one can come across "Japanese glass stones", korean Shin Kwang Baduk (新光, 신광바둑) Glass stones, 6 Brothers glass stones etc.
It would be easier for me to help you find the stones you want rather than try to translate Chinese, which I cannot do. You can contact the factory representatives using the email address for Songyun and google translate. Try to use simple and clear language that google can translate without idiom or error.
Songyun makes "jizi glaze weiqi stones"that are identical to the more familiar Yunzi stones; the black glow green when held up to light. Songyun also makes stones of ceramic, which are opaque, and melamine/plastic, which are useless. Songyun's stones are flat, single context, Chinese-style. However, they also make the Japanese-style double convex stones. The descriptions and illustrations are clear.
Glass stones vary widely in quality. The best I know of are Japanese; they are brilliant white and deep black, identical and regular in shape, and the glass is tough--won't shatter easily. Korean and Chinese glass stones tend to be cheaper glass, irregular, blobby, off-white, and streaked with visible flaws. Also, many of mine have chipped easily.
