Types of Joints Made with Animal Glue Under Different Gluing 
Conditions 
A.— Well-glued joint; made with a proper relation between pressure and consistency of 
glue. 
B.— Starved joint; resulted from the application of pressure while the glue was too thin. 
Occurs frequently on certain woods with animal and other thin glues. 
C— Chilled joint; glue formed into a firm jelly and the pressure applied was insufficient 
to bring complete contact. Light spots are areas of no contact. 
D. — Dried joint; glue dried on the wood before pressure was applied. Poor adhesion 
throughout.
