Tetragonisca angustula flora availability. "T. angustula" honey contains more moisture than honey from typical honey bees and is also more acidic, giving it a complex flavor. Honey and propolis, a glue like substance that bees use as sealant, collected by "T. angustula" have some health benefits for humans. The honey and propolis contain various chemicals that show antibacterial activity towards an infection causing bacteria, "Staphylococcus aureus". Honey and propolis gathered from different geographical areas have different chemical compositions yet they all exhibit some type of antibacterial activity. Another bee, "Apis mellifera", produces honey and propolis with very similar qualities. Forests are being
Animal glue acid solution. The hides are heated, in water, to a carefully controlled temperature around 70 degrees Celsius. The 'glue liquor' is then drawn off, more water added, and the process repeated at increasing temperatures. The glue liquor is then dried and chipped into pellets. The significant disadvantages of hide glue – its thermal limitations, short open time, and vulnerability to micro-organisms – are offset by several advantages. Hide glue joints are reversible and repairable. Recently glued joints will release easily with the application of heat and steam. Hide glue sticks to itself, so the repairer can apply new hide glue
