What is the difference between Coba resin and natural amber

1, the concept of different

Natural amber: is a transparent biological fossil, is a fossilized resin of the Pinaceae, Yucca family, Nannochloraceae and other plants.

Corba resin: Corba resin is the name of the resin of several tree species (RESINS), fossilized and progenitor are included; it is not a proper noun unless the name of origin is added in front of it or the name of the tree species is added.

2. Different forms

Natural amber: amorphous, often in the form of nodules, tumors, small drops and other output. Some, such as the annual rings of trees, are radial texture; can contain animal remains, plant fragments and so on. Low hardness, light texture, astringent, warm, with gem-like luster and crystallinity. Another characteristic of amber is that it is particularly rich in inclusions, such as insects, plants and minerals.

Coba resin: exists in many forms. The hard yellow amber-like koba is one of the cheaper ones. White Koba, like milk is relatively more expensive.

3, the distribution of different origins

Natural amber: Baltic coastal countries (such as Russia, Poland), Burma, Dominican **** and the country, China, Mexico. Mainly produced in Liaoning, Henan, Guangxi, Guizhou, Yunnan, Zhejiang, Chunan Qiandao Lake, Jilin Hunchun and other places. Amber has also been found in several high mountains around Qiandao Lake.

Corba Resin: The Tanzanian island of Zanzibar is the main source of buried corba resin. Kerbal resin is also produced in China, Brazil and some other South American countries.

4, different chemical properties

Natural amber: not all soluble in organic solvents.

Coba resin: they can be fully or partially soluble in organic solvents.
