Lino's Nero Tea

[Jordan Kube]

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

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.

[Pete VanderLaan]

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.

[Greg Vriethoff]

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.

[Eben Horton]

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

[Pete VanderLaan]

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.

[Eben Horton]

Thanks for explaining... that’s an interesting ingredient.

[Bradley Howes]

I did a quick calculation to see what the conversion of rosin to sugar would be. I don't know if sugar would be a suitable substitute though. Based on the amount of carbon in both rosin and sugar, for 1.3 of rosin, use 1.8g cane sugar. Sugar from beets would have a different amount because there's a different amount of carbon per molecule of sugar.

[Pete VanderLaan]

I'd be inclined to avoid changing something you have yet to melt. Try to get some rosin. Sporting goods stores will have bags for pitchers and music stores would have it for bows on string instruments. I would imagine google would turn up sourcing.
If Lino used rosin, he had good reason to. Sugar was not hard to find.

Here's a rosin source, I suspect expensive but a start. Crush it.

When you look at classic recipes, they're classic for a reason and stood the test of time. If you want to change the world, that's really OK but you need a place to stand. I recommend standing with tradition. Go from there. Try this goop. Melt it. report back. Take feedback. melt some more and begin your changes. I started with the encyclopedia Britannica fifty years back. It was a lot more lonely then with Dudley Giberson holding a light on the path. I just continue to think that the belief that you will break new ground this week is unlikely, particularly if you are just now inquiring about incompatibility. This actually is a long rocky road filled with silica stones.

Thanks Jordan. I copied the link to classified ads. I have to wonder out loud how glycerine would work in this.
South Georgia must be nirvana for resin. We get all our fire starters from there. They must whack up a bazillion lbs a year for the purpose.

[Mitcheal Veenstra]

Using rosin in the batch pile instead of sugar could also be about when it puts things in reduction. It has a different flash point that sugar does. That's why sometimes in some formulas you'll see sugar used alongside rosin. It keeps the batch pile in reduction longer as things fire off at different rates/temps. I'd tend to agree with Pete about not changing a formula you haven't melted yet.

[Jordan Kube]

Great observation Mitcheal.

[Dave Bross]

I agree with Mitch.

The experiments I did with sugar had the reduction fading away quickly.

[Pete VanderLaan]

If you want instant fade, try silicon carbide. Here... and gone. A lot of foaming cleanser left in its wake.
