A short 1888 trade-journal article reporting architects' tests of fibers used as binders in plaster. Plates containing Manilla hemp, Sisal hemp, jute and goat's hair were loaded with weights, and the Manilla plate carried the most (195 pounds) and cracked without separating. A second test stored lime-and-sand mortar with Manilla hemp or goat's hair for nine months; the hair was largely consumed by the lime, while the hemp mortar stayed cohesive.
