Lino's Nero Tea
 
That's what we called it at Manifesto anyway.

Sand 100
Soda 44
Calcium 16
Boric Acid 3
Sulphur 3.950
Rosin 1.3
Iron Oxide 2.850
Black Nickle Oxide 1

Just for cane or threading. Overlay onto gaffer duro white for extra opaqueness in those super stretched out cane pick ups. Fun to melt. Not as bad as Pete would have you believe :D

Have fun kids.

Indeed, and the reason they named it that is that when you quenched it in water, the water turned black. I remember the rosin blacks. They lit on fire.
Yum...There are way worse things to make. Furthermore it used real "Sulphur", none of this candy ass "sulfur" you see sold on street corners in Eugene.

well, good ventilation will make it less of a problem. That's the stuff.

What is Rosin?

It's a purified form of pine sap/pitch. You make it by dissolving pitch in a solvent like acetone, then slowly heating the solution up until all the acetone and pine terpenes have vaporized. Changes from a thick sticky liquid into a slightly waxy solid.

It looks to be a reasonable source. I used to get it as rosin bags in sporting goods stores.

It's also traditionally used in cake form on bows for stringed instruments (violins, cellos, etc.).

It does but rosin for the bow is usually in a solid form and hard to mix in a batch.

What purpose does it serve in the glass? a reducing agent?

Pete VanderLaan 11-07-2017 06:37 AM

If you must know:
C15.H20.06
Seems quite the popular go to substance for making hash. In Glass its got lots of Carbon to burn, so I'd say reduction. Not quite sure about the catching on fire beyond all that carbon, hydrogen and oxygen. That's H 20, not H2O as near as I can see. Big difference.

Thanks for explaining... thatís an interesting ingredient.
