Honey extraction abrading the surface of the wax with moving chains or bristles or hot knives. This, while messy, makes the process easier than doing this task manually. Some beekeepers will also harvest (before uncapping the honey) the propolis, a resinous material bees gather to glue the frames together; propolis is used for its medicinal properties. Once uncapped, the frames are then placed in a honey extractor, which spins them so that most of the honey is removed by centrifugal force. Care must be taken to ensure that all frames are loaded correctly, as the comb is angled slightly upwards to prevent
Glue-size Glue-size Glue-size is a painting technique in which pigment is bound (sized) to cloth (usually linen) with hide glue, and typically the unvarnished cloth was then fixed to the frame using the same glue.
