I have had issues whenever I try to mordant cotton with aluminum acetate. I always follow the recipes on websites like Botanical Colors or Maiwa and fix it at the end with the calcium carbonate but the samples are never holding color well. The alum samples are much more vibrant than the aluminum acetate ones. I think the issue is I haven’t been fixing it long enough or the aluminum acetate isn’t properly dissolving. I’ve read it’s really hard to fully dissolve the aluminum acetate too. Does anyone know what could be wrong?
