Mark-S Awesome, thank you for the helpful insight into testing! The cup is not too old, 70s Jingdezhen Porcelain, which I like a lot. Although OCTO has displayed some porcelain in the B&W Appreciation thread which looks to be very fine!!

I grew up using these bowls and dishes, and kept using them even with hairline cracks as long as they weren't leaky. Would love to know your test result if you ever get it done

Thanks From what I can tell, the glaze is not damaged. I might dabble with a little test though per @Mark-S's kind recommendation. If I do, I'll report back.

just fyi, i moved the recent conversation to the Jian & Tenmoku Bowls topic since it wasn't really about porcelain.

Porceram [Proceram]

hi, welcome to teaforum

sometime during 1939-1977:

https://www.aubagne.fr/decouvrir-aubagne/patrimoine/patrimoine-industriel-875.html wrote: Impossible d'évoquer les grandes fabriques sans faire référence à Procéram. Cet ancien fleuron de la céramique aubagnaise fut créé en 1908 sous le nom de "Société des Faïenceries d'Aubagne" (S.F.A.). Spécialisée dans la vaisselle et les carreaux, la S.F.A., poussée par des innovations permanentes, s'impose très vite comme un des plus grands producteurs locaux. Renommée brièvement Faïencerie Nouvelle de Provence entre 1929 et 1938, elle passera à la postérité sous le nom de Proceram à partir de 1939. Si la société a cessé son activité en 1977 et que l'usine a laissé place à un nouveau quartier, les carreaux de Proceram ornent encore certaines devantures d'Aubagne. Quelques fresques des frères Vaglini qui y travaillaient peuvent encore être observées aujourd'hui, notamment dans la rue Peypagan et sous les halles de la place de Guin.

Bought these off of ebay around 10 years ago. It's a matching set of 5. Don't know much about them. Anyone have any info?

I want to learn more about the different grades of porcelain. I understand that the basic break down is between hard paste, soft paste and bone china. In terms of non-bone china, there appears to be a continuum between hard paste and soft paste, depending on the type of white rock used, the amount and quality of kaolin and the incorporation of additives like glass.

I heard that one way to tell the level of hardness is by checking the texture and porosity of the unglazed bottom rim. If it is very hard using high quality material, this bottom rim would consistently feel smooth and almost rock like with almost no "sandiness" in the texture. Additionally, it would not stain/discolor or get dirty readily because it would have very low porosity.

Edit:

I found a lot of useful information about this in the mud and leaf blog:

Just wanted to share some cups I collected recently. I think the green and the red may be LQER while the rice grain pattern one is hard to tell. The green and red cups for sure are bad for drinking as they most likely have lead issues. Any seniors want to chime in on the rice grain cup?

Just a word of caution: I have the same kind of red cup, did a lead test and it has have heavy lead leeching, don’t use it!

@Bok
The green one should be equally bad as the red one. Similar glaze with different color. The rice grain maybe hopeful

For what it's worth – a lot of these red one were actually mainly used for the house altar to pray to the ancestors. Set of three filled with tea or alcohol.

Can't die to lead poisoning if you're dead already

I typically brew black tea western style and I'm looking for a larger tea pot, around 200-250ml. I am strongly considering porcelain as the material in a traditional teapot or perhaps a Kyusu. What are some reputable vendors that I should be looking at?

Thanks in advance

@gregcss
For that size of porcelain, the cheap route would be vintage/modern jingdezhen made teapots from eBay. If you want new pot with designs here are two vendors:

I am using a 1970-1980s jingdezhen rice grain pot. I think I bought it for 5 bucks lol

Maybe this is heretical but i like to do western brewing in a glass french press, which is easily scalable, cheap and relatively convenient to clean
