As I recall, some folks use table salt for salt bars and don’t have a problem. Maybe you should start a thread before you re-render.♀Realized that I used iodized salt to render all of my lard and tallow. Which means all my lard and tallow has iodine in it. Which is a metal that can cause DOS...?
Welp... Maybe I'd better make a lot of pie crusts? And I love tamales...
But maybe I can re-render this and make it soap safe.
Iodine is NOT a metal, it is non-metallic. It is in fact a halogen, meaning it is a salt former. (link)

As for causing DOS, even though halogens are oxidizers, I have not had DOS in my soaps with iodized salt added, although I do not purposely use iodized salt in my soap & when I have done, it was in small amounts. Iodine is the least oxidizing of the halogens listed on the periodic table, but I doubt you're going to be adding any of the others to soap, except if you use chlorinated water in your lye solution, in which case you would need to know that chlorine is a stronger oxidizer than iodine.
When have I used iodized salt in soap & why? Sometimes I make soap when I travel & because of that, I have on occasion used salt packets that indicated 'iodized salt' because that was what I had available to me at the time. Most of the time, however, I do use non-iodized salt when making soap with added salt.
But as I said, I have no recollection of any of those soaps going rancid. That is not to say that it cannot happen, of course it could; I just know that I have not had that experience as yet.
It also depends on the oils used in a particular soap formula. Oils with a high iodine value are more susceptible to oxidation, so if a soapmaker uses a formula high in unsaturated fats, then perhaps that soap would be more likely to develop DOS than a formula low in unsaturated fats. Grapeseed oil, for example is prone to faster rancidity (Iodine Value = 131) Lard's IV is a mere 57, so less susceptible. Coconut Oil's IV is 10, so if you made a Lard/CO soap, you'd have less of a concern that if you made a Grapeseed/CO soap because the combine Iodine Value of those soaps would be drastically different if the CO was at the same percentage in the formulas.
Perhaps of more concern is this: Will the iodine render your lard more susceptible to oxidation now while it awaits usage in your refrigerator? I don't know, but do remember it has a low Iodine number to start with, but
perhaps you should keep an eye on it, make some soap with it soon & keep an eye on them and make lots of tamales & pies.
Honestly, it has nothing to do with the season in that case. They chose the scents to match the wines and ciders and, I must say thar the scents they chose work well.

I am an idiot--I was sitting on the couch with the periodic table on the wall behind me when I typed that nonsense. Thanks for the helpful info on which are oxidizers... Ochem is next semester, so I haven't gotten there yet! Understanding the why makes such a big difference. I've never really understood the importance of iodine value, and I'll start paying better attention to it. The batch that went bad on me was vegan, but had a high IV. It eventually spread to the 3 leftover lard bars in the same curing box (same scent) but those were 6 months old; I should've bagged then up already.Iodine is NOT a metal, it is non-metallic.

Glad you posted this today--I've started reformulating my HP recipes with lower linoleic/linoleic acid, and I'll watch the IV now, too. THANK YOU!
I unmolded a batch of (my version of) Earlene's blacksmith soap. It's my base oil recipe with her recommended percentages of borax and fine pumice. Scented with a lavender-chamomile-pine EO blend, it's a big hit with our mechanic and yard maintenance crew. My husband and I use it, too. It does such a great job of cleaning off the grime without stripping or drying the skin.

Today I unmolded my lavender-mint ombre soap. And then I made yet one more syndet shampoo tester bar. I'm hoping this is THE ONE 
Today I packaged my winter Solstice Salt Soap, and prepped my summer batch. Happy Solstice!!
I just placed a small fragrance order from WSP during FOsale. I finally ordered some nag champa.

Earlene, i just want to pop in quickly to thank you for your posts. I always learn something from your knowledge, expertise, and clear communication which enables me to understand the science/process. I appreciate you!
Just to repeat myself within a few days, but I love @earlene's blacksmith soap too! The dirt just rinses right off. I'm used to scrubbing my hands red and raw but no more! I've gotta coupla tweaks to make but highly recommend it!
I "tried" to make a very small batch of soap to make some dough (first try) at this... however.... I think I didn't check my temperatures correctly (measured spatula??)… As one tiny blend and... scrambled egg 
Not to be defeated though I turned it into my first go at hot process soap
I've wrapped it up and will see if I can use it in my shiny new extruder tomorrow... who knows! It's all an adventure

Nutshell: more water, less salts. Details at Borax soap
Thanks, I remember that post now. And yet I still added SL to my latest batch - which is admittedly a bit crumbly around the edges.
Please do not call yourself and idiot! We all have moments of clarity and we all also have moments of misremembering. We need to forgive ourselves for occasionally misstating or misunderstanding or whatever other slight gaffe. We are human, after all, not gods. I know I often have such moments where I cannot even think of the descriptive word I want and it can be frustrating trying to complete a sentence when a particular adjective just slips away into the ether.
Thank you both. I would always defer to DeeAnna and others with more scientific knowledge & expertise. It's really been a long time since my chemistry classes & the fact that I remember any of it sometimes surprises me.
@AliOop & @Zing, I am so glad you found something useful to you in my Blacksmith soap. I highly encourage tweaking to fit your own personal preferences. The recipe I shared is not set in stone; it was just the one that my brother preferred at the time, so that's the one I shared. I am not above changing out the oils to fit the needs of the user (my brother) or personal preference (the soapmaker) or even based on availability (supply). What with the supply chain problems of late, I am grateful that soapmaking is so versatile and that we can easily adjust a recipe to use what is available at any given time.
I’m using my dishwashing machine to wash soap dishes for the first time. It’s like a shower steamer for my house! It smells so good!
Make sure you scrape out all the soap you can and put them in as clean as possible otherwise it can gunk up your filter.
Thank you. I wiped them out pretty well. I rarely use my dishwasher, I forget I have it. Would horrible things happen if I put a touch of dawn?
Also, I’ve used the search function, can’t find. What is the name of the book of labeling laws?
