On detached stems only traces of resin were visible that were too small to distinguish from background levels using this method. Much seemingly vital information, such as composite makeup and resin chemistry, is totally ignored. Primary resin is produced by the petrochemical industry and is made from raw materials, such as naphtha and chloride. Import of secondary resin is not an option at the present moment as there is no trade flows in this commodity. Samples were incubated at room temperature for 5 min and placed in the magnetic stand for resin separation. They get further improved by the opened dentinal tubules allowing the formation of resin tags in the filling material. The imports of waste plastics goes down as less secondary resin is used in the final production processes and therefore inevitably so does demand. Therefore, substituting primary resin with secondary resin can in theory reduce costs while still meeting final demand. Incense is the resin or sap or, metaphorically, the "blood" of trees. Modellers also incorporated paraffin wax, tallow, spermaceti, and the resin balsam. After staining, each slide was washed with distilled water and sealed with synthetic resin to prevent it from drying. One anion and one cation resin bag were secured to a plastic stake with monofilament line at six random locations in each 1-ha plot. The resin consists of monomers or polymers which form a network during the drying process. Environmental factors strongly influence resin duct size and so have considerable potential to affect relative resistance of the different species.
