We have an investigatory project which includes adding pine needle ash to bricks to make them more durable.Now, we are wondering if which has more adhesive property, green pine needles or brown ones? Please...please help.and if you know the answer to my question or if you want to give information regarding our investigatory project, just e-mail me at firstname.lastname@example.org. or hash_014@ yahoo.com. Gee, thank you.
Which is stickier, brown pine needles or green pine needles?
As a collector of pine sap (amber) in my humble opinion the fresh green needles contain more resin. I have also observed green needles have a subtle barbed finish which I believe are small (leafs) that open to give the needle more surface to process light.
Also the green, with a little fresh sap, tightly woven together make a wonderful smudge stick...For those into that sort of thing.
Reply:green...try crushing them. brown ones are dry.
Reply:green most def, have you ever crushed either between your fingers, green are fresh of course and still moist, they leave your hands very sticky. Dry pine needles just crumble into dust, no moisture left....
