I am happy to report that this was accomplished according to the timeline, and with better success than originally anticipated!
The Big Idea was that I would finish a block of soap, formed in a homemade mold, by Sunday night. I was actually able to make and mold the soap on Friday morning and pop it out, cut it up, and leave it to cure by Friday afternoon.
The item I thought would be the biggest problem, the soap mold, actually turned out even easier than originally planned for, since I had the project on my mind so much. I had initially thought about cutting up cardboard, hot gluing it together, then lining it with wax paper to prevent the soap from sticking when it was first poured in. Over a few days, this was whittled to the idea of using an empty rectangular half gallon milk container, made of stiff waxed cardboard. This would still require some cutting and gluing, or at least compressing and gluing, since the top side of the milk container is actually triangular and would need to be formed into an equally flat surface to match the other side. While inspecting a milk container from the recycling bin, I happened upon a plastic (awful, I know!) egg carton, the top of which was actually a PERFECTLY formed rectangle, and the thin plastic had the extra advantage of being flexible, so I figured I could just pop the hardened soap out of it and use it again, thus continuing the recycling (and the whittling) process.
With the mold situation under control, I tackled the next problem--that of using an extremely corrosive and easily spilled substance in the same house as a small toddler--with the easiest solution I could manage. My daughter is not terribly reliable when it comes to taking naps, and some days goes all the daylight hours without conking out. We don't really push a nap schedule in our home, as we figure that she'll sleep when she's tired, which she demonstrates on a regular basis, as we routinely find her passed out on the carpet in the living room. Instead of waiting around for Maddie to be tired enough to nap, I just circumvented the system by getting up early enough in the morning that I could make the lye water and mix the soap before she would wake up. Simple enough.
Now, in making lye water, there are some precautions to consider. Anyone who has seen "Fight Club" is familiar with the concept that moisture + lye + flesh = chemical burn. I am not keen on the idea of "hitting bottom" by creating intolerable pain in the pursuit of understanding that "someday [I] will die;" I just want to make soap, and so I take at least moderate measures to prevent the aforementioned agony. I wear long sleeves and latex gloves to cover the skin of my hands, wrists, and arms, and, since I do not own safety goggles, I wear sunglasses to prevent any stray lye specks from flying into my eyes. Powdered or flaked lye, known more accurately in this case as sodium hydroxide, is combined with water to create lye water, which is then added to melted fats to create soap through the process of saponification. When lye is added to water, it creates toxic and corrosive fumes, and also very quickly heats up the water it has been added to. Adequate ventilation is a must to avoid injury. Since I do not have a fume hood in my house, I actually complete the process of adding lye to water outside on my driveway.
So, at 7am on a cloudy Friday morning, I am outside squatting in my driveway, wearing sunglasses and blue latex gloves, and gingerly pouring a white substance into a small jar of water at an arm's distance from my body. I am sure I look crazy to any passersby, which I can confirm from the one passerby walking his dog, who eyed my stance and my get-up, and probably wondered if I was a meth head out cooking up a morning batch (incidentally, I had to jump through a couple of hoops to procure the lye online, as it seems to be an ingredient in the production of actual meth). I stir the solution with a stick dropped from our tree, since I don't want to put any of my metal or wooden spoons in the mixture and risk their becoming pitted and nasty, then leave it on my porch to cool down. Success!
From there, the process was a snap. The only snag I hit was when I tried to pop the soap out of the mold. It was pretty well stuck to the plastic, so I ended up having to make cuts in the carton to free the soap block in once piece, a bummer because I wanted to use it again. On the bright side, between the time that I poured the soap into the mold and then tried to pop it out and failed, I remembered that I have a silicone (read: flexible) loaf pan, and that I could use that item in the future to easily mold soap.
Cutting the soap block went easily, as well. (Instructions online will lead one to believe that you run the risk of crushing, smooshing, or otherwise damaging one's soap if the proper tools are not used at the proper time--I just used a sharp, straight-edged carving knife, and all went well). The soap is now curing as I write!
Given that this is now Tuesday, and I completed the actual soap making (if not blogging) well before the Sunday deadline, this Big Idea is a success! I actually did another soap block this evening after coming home from work, as one of my Long Term Ideas (another category entirely from the Big Idea) is to make enough soap that it can function as Christmas gifts to family and friends this year (spoiler alert!). The soap is setting in the loaf pan, so the hope is that this will go as happily according to plan as I hope it will.
During these past few days, I have been pursuing a few Big Ideas in the learning and planning stages only, such as researching how to acquire and house chickens on my small property, and building raised beds for vegetable growing on my concrete parking pad next to the house (as there is no available land for gardening). I am not ready to commit to either of these as my next, true, Big Idea. Instead I'll go with:
The Big Idea: getting my sewing machine serviced so I can get back on those scores of unfinished quilts.
The Small Steps: finding a place in RI that services machines, loading up the sewing machine and transporting it out, negotiating a price for said service that we can afford (hey, times are tough), then actually going back and picking the thing up
The Possible Pitfalls: not finding a place that services my particular machine, finding a place but having it's location be "off the island" and thus a perceived grueling expedition to get there, not having enough money in the bank to service the machine, putting off going back to pick it up because it's a pain to drive and I already drive too much in my job, etc.
The Deadline: I will give myself one week (so, until next Tuesday evening) to complete this task, including getting the machine back into the house.
Onward!
