Hide glue is measured on the basis of its gel strength, a measure of how many grams of force it requires to depress a 1/2” plunger 4mm. into a 12.5% protein solution of the glue at 10 °C.

Glue is manufactured in standard grades from 32 to 512 grams.

192 gram strength is the most commonly used for woodworking

251 is the highest normally used for instrument building

135 is the lowest used for general woodwork.

Types of wood glue

Urea-formaldehyde

resin adhesives feature a low effective cost, low cure temperatures, resistance to microorganisms and abrasion, and light color.

It does not creep, and can be repaired with epoxy.

It can rapidly deteriorate in hot, moist environments, releasing formaldehyde

Phenol formaldehyde resin

is commonly used for making plywood. It is cured at elevated temperature and pressure

polyvinyl acetate

(PVA), also known as "white glue" or "hobby and craft", and aliphatic resin emulsion, commonly referred to as "carpenter's glue" or "yellow glue", which has similar relative ultimate strength.

The two have different grip characteristics before initial set, with PVAs exhibiting more slip during assembly and yellow glue having more initial grip. PVAs are non-toxic and very easy to use, but hard to repair since nothing else sticks well to the hardened glue. PVAs will creep under constant load.
