I have not found a successful way to root cuttings from my Kieffer pear. I've tried several different ways, soil, water, with and without hormone. Which is not to say it can't be done, just that it's not foolproof/easy and I don't know how.
I haven't tried pear, but generally cuttings will work better in a moist media like perlite, vermiculite, sand... rather than directly in water. Controlling the humidity(ie mini-greenhouse like you have is generally good. Roasting in the sun, less so.

Jessica and Dillon,
Any idea what max temp a cutting can withstand? Or even a ballpark?
Do y'all usually do cuttings inside? Outside without mini greenhouse?
It was supposed to have been 33F last night and a high of 50 ish, so I doubt it is already too hot (might have frozen it actually), but its good to be mindful. I might stick a spare thermometer in the bottle next time. I'm curious yo see how hot it actually is. If I do should I measure air temperature or water temperature?

Little greenhouses like that can be REALLY effective at heating up when in direct sunlight.
The cuttings I did in my little greenhouse seemed to tolerate the early spring temps approaching 90F for brief periods. These were kept shaded within the greenhouse, though. This may be higher than optimal, certainly my success rate wasn't terribly high. I can't claim to be an adept with cuttings just yet; I've propagated dozens of cuttings successfully, but I'd really like to achieve a higher success rate. A misting bed is on the menu, but not this year it seems!
I've done cuttings inside, sometimes on a heatmat(good success), and outside. Outside, I've done them in plastic-covered totes in a shady area(lowest success), in totes in a shed(next lowest) and in my greenhouse as soon as it was done(much better). In each case the tote acted as a mini-greenhouse for smaller containers with moist media(perlite, vermiculite, sand...). Inside and in the greenhouse I also used containers outside of totes, with a bag overtop to provide some humidity.
