So my search turned up nothing. So here goes, the weather here in Iowa decided to change last week from perfect to cold. A batch of soap that is about 8 weeks old suddenly developed a lot of soda ash on it. 1. Is it the cold? 2. Does this mean it wasn't fully cured? 3. If I ship any soaps, can they develop ash? If so what can I do to prevent it? I know the first part of #3 is yes. Thank you in advance for your patience and wisdom.
