Gum Copal 100 grams

Gum copal is a resin produced by the sap of the forest tree (Daniellia sp.), due to common impurities and differences in regions, gum copal ranges in colours from blacks to yellows to whites. Gum copal is usually only 100-1,000 years old and it has not yet fossilised. Gum copal is a semi-fossilised, amorphous resin which has a unique set of properties such as resistance to water, solubility in alcohols, and has the ability to give glossy finishing along with possessing superior binding abilities.

Usage:

Gum copal has a very wide variety of uses in both past and present times. Primarily used as an incense by ancient civilisations, it also found usage as an early form of glue, and traditional medicine for cases such as dysentery, stomach pains, dizziness and fright. Today it still finds popular usage as an incense. In addition, it finds a niche as being a varnish or waterproofing material (as when it is heated with certain oils, it becomes nearly transparent). It also can be used as ingredients for adhesives, perfumes, printing ink, paints and films

Qualities:

PWS- This is the highest grade for gum copal, white in colour and 99-100% purity, it is used for making varnish specifically for wood surfaces. Its result is very good lustre and very good in resisting external scratches. Plus it dries to a hard and shiny film.

DBB- This grade is pebble sized and whitish yellow in colour with about 90-95% purity. This is an economy grade and ideal for production of low end varnishes, its solubility is good. It can contain some black copal but it is still perfectly and easily dissolved in alcohol solvent mixtures. It is also the most common use for incense.

WS- The lowest grade for gum copal with larger chunks and black in colour with about 60% purity, the impurities include tree-bark and soil.

Powder- The is the leftovers from the processing of PWS and DBB, usually used for varnish.
