Part 3 of an International Correspondence Schools instruction paper on silk testing, covering additional tests for raw and thrown silk. It describes the serimeter test (breaking strength and evenness), the serigraph test (strength, elasticity, elongation), the gauge test for defects and cleanness, the twist test, the mirror test for evenness, and the measuring test for skein length. Each section explains the apparatus, sampling, procedure, laboratory record forms and testing-house certificates, with worked rules and examples. Examination questions are at the end.
