View Photos They say love is a burning flame. But love gone wrong can make you take a torch to someone’s you-know-what. Opt for a controlled burn (and avoid a prison sentence) with industrial designer Jen Pearson’s firestarter kit. Her efficient yet handsome home designs, including terrariums, a love letter kit (blasphemy), and popular apothecary matchstick bottle, smolder with recycled and sustainable materials. The firestarter kit goes a step further, with harvested materials (locally gathered pine and needles, sap from Sonoma) and fifteen matches piled in a glass test tube. Mound each element as it appears in the bottle and light ’er up; just add the appropriate fuel (forlorn photos, letters, a lock of hair) and relish as lovesick mementos go up in smoke. The quaint bottled kit is as appropriate on your mantel as in the back woods. Pine no more. Available at Rare Device, 1845 Market Street, at Guerrero Street (415-863-3969 or raredevice.net); Magpie & Rye, 262 Divisadero Street, between Haight and Page Streets (415-701-8701), $16.
