the glass fittings. In all trials, some bitumen would solidify within the small glass fittings, within<br />
the plastic tubing between the flasks, or in the water-cooled condensers (bitumen collecting<br />
within the glass fittings is visible in Fig. 24). After transferring the products to the bottle, a<br />
fraction <strong>of</strong> bitumen would be left within the collection flasks as it was too viscous to flow into<br />
the bottle. This required an acetone wash <strong>of</strong> the collection flasks and glass fittings after each<br />
carbonization trial. The waste acetone from these washes were consolidated and dewatered for<br />
increased bitumen collection.<br />
