Well, I looked over that tek. Even the poster to that link didnt know how to follow those directions. Many of the steps are not based in solid lab language. "Heat it till it is hot for 1 hour" ... I cant find hot on my thermometer.
I'm not saying that with a bunch of experiments that tek cant be fixed. But do you have the time to beta test that tek?
Personally I have not had any luck with a tek that used Vinigar, or lemon juice.
HCl is at the regional hardware store sold as Muriatic acid. Either 33%solution or 20% as pH balencer for pools. 8$
VM&P Naptha same hardware store, same isle as acid. Paint strippers section. 14$
Now NaOH, sodium hydroxide, caustic, caustic soda, lye. Its all the same thing. You can find Food grade caustic at culinary stores.. while your there pick up some whipits. Caustic is used for breads or pretzels. Or if you have a friend working at the pretzel place in the mall. 4$
http://www.essentialdepo...ood-dsh-Grade/CategoriesTake the high road. Follow either an STB or A/b tek. You'll be sucsessful you'll be rewarded, You'll make love to your own mind.
If this is still too tough... give the Whipits a try.
I will not share my spice with unceremonious tea drinkers.
