very comparable to those for coal tar and petroleum pitches. A maximum value of 48 wt% for biopitch # 04 and a minimum of 26 wt%, for biopitch # 01, were found. β-resin, defined as TI minus QI for each sample, is responsible for the binder power of the pitch. It is very high in biopitches because of the very low QI and high TI (Marsh, 1997).

Pitch Drop experiment - University of Queensland

The experiment explained. In 1927 Professor Parnell heated a sample of pitch and poured it into a glass funnel with a sealed stem. He allowed the pitch to cool and settle for three years, and then in 1930 he cut the funnel's stem. Since then, the pitch has slowly dripped out of the funnel - so slowly that it took eight years for the first drop ...
