Flexibility Should not be too low or lasting may be uneven. Lies in the right range. The direction of tightness varies but is predictable. Tanner has some control over the degree of tightness. Plasticity Normally should be low to resist shape loss in wear, but should be possible to make it during lasting, then low again afterwards Very good.
Plasticity is increased by moisture and lowered again on drying out.
Easy to flkatten wrinkles on lasted margin. can be shaped at room temperature given time Cutting Should cut cleanly in the clicking, skiving and splitting operations. Should not blunt knives. Can be split very thinly. Expand slightly in moist conditions.
