Hi Carl,
Long, long ago, when the world was young, had the great privilege of
working for six months with Zuni Zelitch in far off Connecticut. In
those days the stuff that you were asking about was called silicone
rubber (Dow Corning or something similar). Would be described in one
or other of the references below. Used the rubber to make a negative
and nail varnish painted on to the surface of the solidified (cured)
rubber to make a transparency that could be transferred to a slide
for microscope inspection and measurement. Worked very well for
tobacco leaves..
WALKER DA, I ZELITCH 1963 Some effects of metabolic inhibitors,
temperature and anaerobic conditions on stomatal movement. Plant
Physiol 38: 390-396
ZELITCH I, DA WALKER 1964 The role of glycolic acid
metabolism in the opening of leaf stomata. Plant Physiol 39: 856-862
Best regards
David
