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
Glue-size high perishability of linen cloth and the solubility of hide glue. Well-known and relatively well-preserved — though substantially damaged — the most notable examples include Quentin Matsys' "Virgin and Child with Saints Barbara and Catherine" (c. 1515-25) and Dirk Bouts' "Entombment" (c. 1440-55). In German the technique is known as "Tüchleinfarben", meaning “small cloth colours”, or "Tüchlein", derived from the German words "Tüch" and "Lein" ("fabric" and "flax"). A binding agent for pigment was made by boiling animal skin mixed with other organic tissue and applied to linen, itself prepared with a thin layer of glue. The linen was ground,
