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 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
Wood glue do not adhere well to hardened PVA glue. PVAs will creep under constant load. "Elmer's Glue-All" is an example of PVA adhesive. Aliphatic resin emulsion, commonly referred to as "yellow glue" or "carpenter's glue", has a similar use profile and relative ultimate strength as PVA. The two glues differ in grip characteristics before initial set, with PVAs exhibiting more slip during assembly and yellow glue having more initial grip. Brands include "Titebond" and "Lepage". Contact cement for wood veneers. Hot glue for temporary uses. Homemade glue for paper, wood, and internal uses. Several wood glues have poor "gap-filling" ability, meaning
