4. Painting on Bark is the oldest form of Aboriginal art but many bark paintings have perished over time. Not only is the bark prone to decay and disintegration, but the ochre paints too need a stable substrade (base on which to paint) to lengthen their own relatively short life. 5.ainting on Bark is the oldest form of Aboriginal art but many bark paintings have perished over time.

If CHG solutions come into contact with eyes, wash them out promptly and thoroughly with water. You also should avoid contact with the meninges or the middle ear. CHG is toxic to nerve tissues with direct contact, although this has not been reported with currently used agents.
A salt water system or âsalt water chlorine generatorâ (SWCG, SWG) is used to replace traditional chlorine with chlorine produced from salt in the pool water.n SWCG doesn't generate salt -- it has to be added by hand -- and even if it did, generating salt wouldn't sanitize your pool. (Salt is NOT a sanitizer!) SG, Salt Generator, is worse than SWG for the same reasons. SCG, Salt Chlorine Generator, is somewhat more accurate, but confusing and not as common as SWG.
