Propolis Propolis Propolis or bee glue is a resinous mixture that honey bees produce by mixing saliva and beeswax with exudate gathered from tree buds, sap flows, or other botanical sources. It is used as a sealant for unwanted open spaces in the hive. Propolis is used for small gaps (approximately or less), while larger spaces are usually filled with beeswax. Its color varies depending on its botanical source, with dark brown as the most common. Propolis is sticky at and above , while at lower temperatures, it becomes hard and brittle. While foraging, worker bees primarily harvest pollen and nectar,
Speed glue few extra grams may cause the player to not perform as well. The more the glue builds up on the rubber, the more glue must be applied on the next application to achieve the same effect. After 5-10 layers of glue, some players peel the old glue off to reduce the weight of the sponge, and to reduce the amount of glue needed to obtain the optimum effect. Another disadvantage is that the increased tension on the sponge from the glue will cause the rubber to wear out faster than usual. In order to prolong the life of the rubber,
