untitled the article on mastix is awful but do not merge it with gum arabic they might occasionally get confused but two are not the same mastix is the resin from a tree called pistacia lentiscus and gum arabic is made from the resin of two species of acacia tree they have different properties and are used for distinct purposes in the culinary and artistic fields mastic resin it is not gum arabic gum arabic system made of acacia tree and mastic is made out of pistacia lentiscus tree unfortunately many people in the world do not know this spice is known to only a few in the middle east and a secret except for people as a great healer i ask not to be confused with gum arabic is something else entirely mastic is made of wood and pistacia lentiscus and gum arabic is produced from a acacia tree resin this spice also does not appear in any dictionary in the world and the first time he appears in the encyclopedia that he always appears in the encyclopedia as a resin of pistacia lentiscus mastic and gum arabic are indeed two very different substances from different plants with different properties and uses gum arabic is soluble in water and once formed the basis for the glue on postage stamps and envelope flaps it is also used in vernice bianca which would not work at all if someone tried to substitute mastic for the gum arabic mastic finds one of its uses in drying oil type varnishes incorporating for example linseed oil mastic is not soluble in water in fact a small piece of it makes a long lasting chewing gum with this in mind i will boldly remove the merge tag on the mastic page as not having a snowball's chance of passing
