I just ordered more Lye and made the mistake of ordering Technical when I should have gotten food grade. Is there, anything I need to do differently? Do I use the same amounts or it one stronger than the other?

TIA

I've used both. I usually buy whichever one is cheaper. Just as long as it's just lye and nothing else, you'll be fine.

The difference is that food grade lye is triple filtered. It's cleaner. It's not any less strong than tech grade so you don't need to do anything differently. Take the same precautions that you would with tech grade. I switched to food grade last fall after having too many problems with technical grade lye, but the tech grade is less expensive (or has been wherever I've ordered) so if it works well for you, you may want to use it instead of food grade.

Thanks guys, I went back to the website where I bought it and they had that on the side of the page as one of the most commonly asked questions! I panicked when I got it and it was in different bottles. I'll just switch back when I need to order more. Thanks so much for the advice.

Food grade lye? :? Surely lye is never used for food.

Actually it is. It's used in toothpaste, pickles, pretzels and lutefisk.

It's also used to make hominy and grits.

Wow, you learn something every day :o Who would have thought? I'm going to check up and find out all the info about lye, and everything it's used for. This forum is so enlightening :)

Olives too. It's used to cure green olives. Some people swear that it's the lye that gives the good kind of pretzels (not the bagged snack kind) the great crusty sort of exterior, but I dunno. I'm not a pretzel fan.

we sure do. :)

Don't forget that once Lye has reacted, it's no longer lye.

NaOH + H2O --> Na+ + OH- + H20 + Heat

In soap the free Na ions, attach themselves to the oils, turning the oils into salt. And Giving them a hydrophilic side (meaning it's attracted to water) Meanwhile, the soap molecule gains a positive charge in this reaction also. So one side attracts dirt, and the other side attracts water, and washes away. :)

Sorry if it's too much chemistry. I do like chemistry.

Lye solution is also used to adjust a product's pH like a facial serum.
