No, it's not anywhere near the same at trace as it is after aging. It will definitely change.

How are you testing your soap batter, Lee?

In order to accurately test pH of solid soap, you need a lab. On the other hand, you can zap test for free. And what you need to know is if there is free lye(hence the zap test), not the pH.
Strips and phenolpthalien drops are notoriously inaccurate and are truly not worth using. Most people don't use the meters properly, so most pH meter readings aren't accurate either. In addition, Susie is correct that pH doesn't tell you if your soap is skin safe or not. The zap test is a better alternative for that.

Try it after a week for most soaps. If you have free lye, you will know it.
I licked my soap...and I liked it!

Lol! You don't have to lick the soap. Just wet a finger rub it on the soap and then touch your tongue with the finger. Zap testing is very accurate and unmistakeable. If you think you may have been zapped - you have not! You will not have to question zap. It does not hurt, but is an uncomfortable sensation, not a taste. If you get a zingy taste it is the EO / FO , not zap.
OK. Somewhere on this forum is a video of soap licking. First she did the finger sudsing thing and if that was a "negative" she actually touched the bar with her tongue. That's where I got the licking soap from. (BTW, I only did it once and was spitting for hours.).

I am an unabashed soap licker I do try only to do it w/the little stubby sampler pieces from trimming the bars, though!

You know guys, this gives soap addiction a whole new twist!
I'm also a soap licker. All my soaps have different tastes you know... lol. The first time I zap tested a salt bar I thought "WOAH, thats salty!" next thought was "oh yeah, duhhhhh, its a salt bar!"
Then your soap is safe to use and you'll remember to stop swearing - win win!

Bah, I consider zap testing to be gaining swear credits for the future. Of course, I freely spend those credits when zap testing high CO soaps - those taste particularly nasty to my buds.
