Jual Gum Copal

Jual Gum Copal is a resin produced by the sap of forest tree in the genus Daniellia. Gum Copal Due to common impurities and differences in regions, gum copal ranges in color from black to yellow to white. Gum copal, along with ivory and slaves, was a significant export from East Africa in the nineteenth century. Gum Copal can have an appearance similar to amber and may be mistaken for it. Unlike amber, gum copal is usually only 100-1,000 years old and it has not yet fossilized

Gum kopal is most commonly found in East Africa and Indonesia, but is also found in tropical regions such as South America, Malaysia and the Philippines.

Throughout history, amber and gum copal have been mistaken for each other, as it is extremely difficult to tell the difference between the two. However, a drop test using an alcohol or other solvent will leave amber unaffected, while copal’s surface will become sticky. A heat test can also be used as amber will soften and blacken its surface and copal will begin to melt.

Another key difference between the two lies in what specimens are inside the material. As both amber and gum copal are produced from tree sap hardening, insects and other organisms can be trapped inside (an idea which provided the basis for DNA extraction in Jurassic Park). Depending on whether this organism can still be found alive in the present or recent past can give reference to the age and identification of the sample.

COMMERCIAL GRADE

  • DBB grade is pebble-sized and whitish yellow in color with about 90-95% purity. This is an economy grade, ideal for production of low-end varnishes. Its solubility is good. It can contain some black copal, but it is still easily dissolved in alcohol solvent mixtures. It is the most common grade for use in incense.
  • White soft (WS) is the lowest grade of copal, larger chunks, black in color with about 60% purity. The impurities include tree bark and soil. The powder leftover from the processing of PWS and DBB is usually used for varnish.
