Hi Nonna! The good news is, your soap is probably fine. What you are seeing is a very bad case of harmless soda ash that can be washed and scrubbed off the soap.
The bad news is, that terrible ashing is probably from those specific molds. I get very similar thick, thick ash from a specific set of molds myself. They worked fine for awhile, and now, they produce ash every single time.
Of course, you want to make sure you are doing all you can to reduce ashing, including high lye concentration (or low water, if you prefer that terminology), soaping warmer, spraying the molds with 91% rubbing alcohol before pouring, spraying the tops after pouring, covering the exposed side of the soap for a few days before unmolding, and gelling the soap.
However, I have tried all of those things, and still ended up with soap like this (see my picture, below). I believe there is something in these molds that is causing this extreme reaction, because different portions of the same batch poured into different molds had zero ash.
Again, it is harmless, but so disappointing to have the soaps disfigured like that. Sorry!
