Six half used candle fragrance oils, can any of them go into reed diffusers?

I want to push back on the confident just-buy-a-base answers. Candle oils are formulated to dissolve in wax, and not all of them stay in solution in a diffuser base. I have had two go cloudy within a day and one separate into visible layers within a week, all from a supplier whose oils are excellent in soy. Mix one small test bottle of each and leave them on a windowsill for a week before you commit six gifts. The ones that stay clear are keepers. The ones that cloud are wax melts now.

How long before koji rice smells like anything, mine is at hour 30 and blank

Patchy fur at hour 30 is roughly on schedule and the smell arrives late. My timeline: hours 0 to 18 nothing at all, 18 to 30 faint sweetness and the first white haze, 30 to 40 it starts generating its own heat and you must break the bed apart or it cooks itself, 40 to 48 the chestnut and mushroom smell shows up properly. The heat generation is the part beginners miss. Once it starts warming itself, furrow the rice into ridges and give it air, or you will get a hot core and dead spores in the middle.

I plan six hours of deep work a day and land about two, is six a fantasy for everyone or just for me

Partly disagreeing, because the ceiling is task dependent and lumping it into one number hides that. Writing something new from scratch, three hours is my absolute limit and the fourth is worthless. Debugging or reviewing code, I can go most of a day if the problem is interesting, because the feedback loop keeps pulling me back in and it costs far less to hold in mind. So the honest version is that your ceiling for the hardest category of your work is around three, and the rest of the day can still be real work as long as you match the task to what is left.

1911 terrace priced well under the new builds nearby, what does the survey not tell you about the real gap

Would do it again and would change the order completely. We started with the kitchen because that is what you look at, and then had to disturb half of it eighteen months later when the roof work and the rewire finally happened. Everything that keeps water out and everything that runs inside walls should come first, and every cosmetic decision should wait until those are finished, even if it means living with a horrible bathroom for two years. The money we lost was not on the kitchen, it was on doing it twice.

Batch is perfectly good but ugly, can I melt it back down or is rebatching a different animal?

The cheaper fix for a gel ring is the plane. Bevel the edges and take a thin pass across each face with a soap planer or a vegetable peeler and the ring almost disappears, because the ring is a surface-visible boundary and the contrast drops once you remove the outer skin. Ten minutes for a whole loaf. Failing that, shred the loaf, and use the shreds as confetti in your next batch, where the ring reads as deliberate colour.

Bars from last winter have orange freckles, how long does homemade soap actually keep?

Two things extend it and both are cheap. A rosemary oleoresin extract in the oils at the start slows oxidation, and a chelator like sodium citrate or a proper chelating agent ties up the trace metals that catalyse it. Since I started using both, my sunflower and rice bran heavy bars stopped spotting inside a year. I also stopped buying oils in bulk unless I will use them within a few months, because an oil that is already halfway through its own shelf life when it goes into the pot gives you a bar that starts life halfway to rancid.
