What is lye bloom?  does it look like soda ash?  I did a craft show this weekend.  Another soaper came up and had to find fault with my soap  (Yes a hater)..She said I had lye bloom...I said no it is soda ash.  I'm not too concerned about soda ash, it is only on the tops of my bars and no one else has ever said a thing about it.

the bottom one has white specs that look, from here, to be stearic spots on the cut side.  If you lick the spots do they zap at all?

I figured they were stearic spots.  Just licked, got a bit of a tingle on the spot.  These spots did not show up until recently....  Do you think that is what she meant by lye bloom?

If they just appeared, and now tingle there’s a chance that is what she meant.
 

I’m guessing you have you run your formula through a lye calculator? And that your scale is calibrated?

Sometimes sodium salts can  grow out of porous materials - called efflorescence. 
 

a lye heavy soap can grow those surface crystals with time as the water in the soap evaporates. The one and only visibly lye heavy soap I made was totally user error. I missed adding half of my oils. It got a powdery surface within days and a grainy surface within a few weeks.

And then there was that one time, at band camp, when your scales went Bahoobies up and you ended up having to use all that soap as weed killer...

Yanno, I've got a LOT of soap that I never wrapped and it ALL has this powdery white coating on it. In MY opinion soda ash can only form when there is active lye exposed to air. So if your soap is cured when you cut it there's little chance that you will form soda ash on the bars. To keep the tops from ashing up I spray, nay... I SOAK the ever-love'n piss outta the tops of my soaps with IPA and then lay on a sheet of plastic wrap onto the top WHILE it's soaking wet. That seals the plastic wrap to the top of the soap and the soap mold and I leave the loaf set at least 24 hours before I unmold and cut. Anywho... That lovely white powder coating that I still get on my soaps after a year or so is stearic acid that's been brought to the surface as the FO kinda gasses off, or at least that's my working theory...
