I've been going thru my tutorials and no one has much information on the curing process. I'm assuming I should leave it uncovered but what about the temp of the room and are there any other specifics I should know?
I leave mine uncovered on bakers' racks in a room with good air circulation. When I was first starting out I cured in a closed cupboard, and discovered what DOS is. My soaping room is no different from the rest of the house, I keep it about 68 degrees.
I leave my soaps to cure on a shelf on my plant rack, which has two small, high powered fans blowing on it constantly. And I live in a super humid area (60-80% on a given day this winter) so those fans are never going off lol. I'm not sure the soap is supposed to be under two broad spectrum light bulbs like they are, but I haven't had a problem yet.
I cure mind on wire baking racks that are elevated so that the air can circulate on all sides. Our house temperature is about 68 deg.
I do have a humidifier in the room where I cure... our climate is ridiculously dry in the winter and our humidifier just makes our air more comfortable to breathe. It doesn't seem to affect my soap curing, but most of my soaps cure for 2+ months.
I cure mine in those cheap plastic rectangle baskets you can buy for 3/$1 at dollar stores. I have them on top of a chest of drawers in the guest bedroom. We have high humidity, also, but I don't use fans on mine. I figure they are going to end up in the very humid bathroom, so they may as well start getting used to it. I do, however, avoid oils prone to DOS.
I haven't started adding colorants to my soaps yet, so I don't know if colors will fade. They stay in a very well lit room, with east, south, and west facing windows, and the two broad spectrum grow lights. I haven't noticed fading in my natural soap (milk, shea, oatmeal) or my pink himalayan salt bar. The next soap I do, I want to color it with paprika or turmeric, and I will certainly take note of any color changes.
Stackable bakers racks in a corner top shelf in the man cave. The shelves themselves are heavy duty wire. Good air circulation and low humidity ( wood stove).
Castille and salt bars go in to tissue paper wraps after a month or two so I can write on them and I'm less prone to trying them out too soon.
