True porcelain is a very high-fired (2300+ F) white ceramic that has a transparent quality when thin enough, and Marco Polo introduced it to Europe following his trips to China. At these high temperatures, the body and glaze combine to form a thick bonding layer. Porcelain is very strong and long-lasting because of this. Several imitations are being produced due to the many challenges of working with porcelain. China, bone china, and porcelain are all terms that we use to describe these items.
Although they may not have the same excellent quality as pure porcelain, they are likely to be more affordable.
