Different minerals produce different colour powders (know as the mineral's 'streak') when scratched. For instance, hematite has a red streak, calcite has a white streak and graphite has a black streak. There is also variation within some minerals, depending on impurities.
It should be noted that some minerals are too hard to be scratched by porcelain, and will instead powder the porcelain, producing a misleading white streak.
The color left by a mineral on unglazed porcelain would be its streak.
Unglazed porcelin is porcelin that hasn't been shined or reated with substances.

Dishes made of porcelain or any other clay that are properly fired and glazed are not toxic. Dishes which are underfired or glazed with glazes containing lead may be toxic.
Porcelain is important because it was used to make the terrocotta warriors that were discovered in the tomb of Emperor Qin. It's expensive & good for trade too. Today we can make dolls, fake teeth, cups, dishes, baskets, & other neat things. -savanna
We can make dolls, fake teeth, cups, dishes, baskets, plumbing fixes, and souveniers with porcelain.Hope this helps! But, back then they used it mostly for pottery.DufferflufGina G. ELECTRICAL INSULATORS
From personal experience, I would definitely say the inexpensive line put out by Corelle. I bought service for 8 sixteen years ago, and I still have them all! Boy, am I tired of that pattern. Between Bisque, Porcelain and Stoneware dishes, Stoneware is the most durable and the reason is because it is fired at a high temperature. Corelle dishes are fine, but be careful when they do break because they break into very tiny splinters that are hard to see until someone walks on them barefooted.

of course they're not love... and anyway your grammar is terrible. it should be 'are porcelain dishes chip resistant'
Porcelain is a kind of high fire clay, and is safe and suitable in the oven. Glass meant to be used in the oven is also fired in a kiln and safe. There really isn't much difference between the two dishes and you should get the same results.

Yes, porcelain is still very much in use for making fine china, dishes and tiles.
Dishes were made in China of a special clay found in the country. It is called Kaolin and it is the clay that porcelain is made out of. Porcelain is one of the most fragile of the pottery clays and is the most luminescent.

Porcelain is a fine china made from kaolin clay. It is prized as beautiful table ware as it is durable but rather fragile. "Mother set the table with the best porcelain dishes." "The porcelain tea set was only brought out for the distinguished guests."
The most popular types of dishes with a silver chafing dish are light colored porcelain dishes. It really depends on personal preference.
If the bottom of the dish says oven proof than yes, if it does not than I wouldn't risk it. The dish itself would be fine but the paint or sealant might not be if they are heated.
Porcelain is actually used in too general a way to simply say yes. Actually, thinner, decorative porcelain can't go in the oven. Only stoneware or porcelain specifically made for the purpose can. The best advice is to look at the label or for a stamp on the underside.
