I have one of those vacuum sealers and those bags are boilable. Now I can make it vacuum out and seal or I can make it seal, would one of these work? I've never tried a vacuum sealer, so I wouldn't know how well the vacuum sealer bag would work. I have tried Reynolds baking bags and have had good results. My other question is, if I grate up a whole 4# of this and boil bag it, when I am done, do I add more new scent to it? I don't add more scent to mine. I guess you could add more fo if it's within safe %. I try to stay at 0.7 oz per pound of fo. Also, I am rebatching cause the color came out hidious, will I still have that same gross color? If so, how do I get it to an acceptable color? If the soap is one color, the rebatch will be the same color. If it was swirled or had layers, the soap will be a combination of the colors (for example if there were blue and yellow layers, the rebatch would be green). I have a hard time trying to even distibute the new coloring in a rebatch. :embarasse Some people can do it, but mine is more streaked than if it was colored before the rebatch. You could probably recolor the soap to a darker color, but not a lighter one. For example, I had a Pink Sugar soap that turned brown. I tried to recolor it pink, but it was still very brown after rebatching. :rolleyes2
