(1) Pine resin exudes from cuts in the needles or stem of the tree.

(2) The specimens are quite attractive when cut in half and coated with an acrylic resin .

(3) Their first step was to obtain resin from the pine trees which at that time grew in dense forests throughout Europe.

(4) One core was dried and impregnated with liquid epoxy resin , finally preserving the curious surface pattern of holes.

(5) Defoliation induced an increase in the number of resin droplets in the fertilized saplings.

(6) The scientists also filled the wormholes with a plastic resin to create molds of them.

(7) Imagine windows on which particles of dirt - including tree resin , fingerprints, and bird droppings - disintegrate rapidly when exposed to sunlight.

(8) Organisms preserved in amber (hardened resin from trees) are prized by paleontologists because of the fine details they retain.
