Granular Joiners Glue 500 gr

Still the preferred adhesive for cabinetmaking and instrument making where the glue needs to be reversible.

Hide glue is naturally derived gelatinous glue extracted from animal skins and bones.
The use of glues by humankind is a fascinating history. The majority of modern adhesives or glues are creations of modern chemistry and traditional natural adhesives are progressively being sidelined with one notable exception that of animal protein glues. The use of glue made by rendering animal skin, bones and teeth dates back about 6000 years in antiquity and it remains to this day the adhesive of choice for high value pieces which have to be able, as part of their design brief, to be disassembled and re-glued during periodic restoration or repair. Woodwind instruments are a typical candidate but the use of hide glues find wide application across woodworking. For these users the though of using an epoxy resin is an abomination. Hide glues have none of the safety issues common with modern glue formulations.

Hide glue has good gap filling properties and, unlike numerous modern adhesives, will meld with and stick to older remnants of itself and re-establish a strong bond, a very useful attribute which means you may not need to remove all old glue from joints during a repair. It sets quickly and bonded pieces can be taken apart at any later time with the careful use of hair dryers, hot water on rags or the application of steam.

Very importantly hide glue has a neutral pH (the measure of relative alkalinity and acidity) which is a major consideration for the expected service life of pieces made to last centuries.

Storage - keep sealed and dry and away from heat sources.
Shelf life - many years if correctly stored
Safety - there are no OH&S cautions other than an unpleasant smell.

Add equal weights of hide glue and water (rainwater is best) and allow to stand for 20 minutes or so.
Heat the mix in a double boiler. A double boiler is a outer container with a jacket of water into which an inner container is placed and allowed to heat up. For small intermittent jobs metal containers are fine, a plastic lined vegetable can sitting in a fry pan for example. Heat the mix to around 80 degrees C, (a coffee making thermometer is a perfect tool to accurately monitor the temperature).
Do NOT BOIL under any circumstances. The glue is ready when it has the consistency of a medium thickness soup.

It is best to mix only what is needed and discard the completely biodegradable leftovers although in cabinet shops, in times past, the first job of the apprentice each day was to top up the glue pot which indicates the use of hide glue is not fussy.

Apply to both faces and bring together as quickly as possible. The corner braces so common in old cabinet pieces are frequently held on with hide glue. Apply the glue to the mating faces, squeeze the brace in to place by hand and rub back and forth until it cools and catches.
