The quality of Castellina is not to beat at the price. The glaze is flawless, there are neither inclusions nor recognizable color deviations. It may in the machines and - if you like it - it may also invest in the microwave.
I found some reviews confusing here on the subject of "Made in China" - after all, the service "Made in Indonesia"
These are fine for "Bone China", so bone china. And China is known to the English word for China, after all, was in China as 600 already
Porcelain made. And this today in Indonesia, not in China.
My full purchase tip.
EDIT 28/12/2010: a visit to V & B brings light into the darkness, no bone china, but Vitro porcelain, with its dense fired body, it is particularly resistant to breakage and edge strength, making it ideal for everyday use.
