Handmade soapers have tried to figure out ash for many years, even with chemists help.. None have figured it out.. they have tried different oils, different temps.. some believe fast cooling (air flow)
There is no explanation for ash as of yet.. I get it sometimes and sometimes I don't... same recipe..
Your guess is as good as anyones????
Well that helped Barb :crazy well I guess I will not worry to much then . I am glad its not only me . I figured I can take a damp rag and make it look nicer. I am soaping at cooler temps but not all batches are effected. 1 out of 10 within the last few days .
Almost always if I cover my mold with just cardboard I never get enough ashing to care. And even if I don't in the summer I often don't get ash. The exception is Cybilla's OMH and which ashes NO MATTER WHAT!!!! And I just leave them that way - still sells. I'm thinking it has something to do with the room temp, gelling, air. But it's a mystery...
If I cover my soap with plastic wrap as soon as it is solidified enough to do so I don't get ash. BUT if I don't get that plastic down in the corners of the mold it will be on those corners but not where the plastic wrap touched to soap. Drives me nuts. I much prefer not to have ash. :/
I don't seem to get ash if my soaps go thru gel state. I use milky way molds so sometimes I lose a lot of heat and the coolest ones seem to ash the worst. Usually just dry brush it off with a cloth. It is annoying tho, isn't it!
