# Best UV resin for jewelry making: clear, hard and low odor Source: https://resinandmold.com/best/best-uv-resin-for-jewelry Publisher: Resin and Mold. Picks are chosen from what each Amazon listing states, not from hands-on tests. Method: https://resinandmold.com/how-we-pick UV resin for jewelry making needs to do three things: flow into a bezel or a small mold, cure hard instead of bendy, and come out from under the lamp without a sticky surface. Hard type resins are sold for exactly that, and the bottles look much alike, so this guide compares six of them by what their Amazon listings state: cure time, the lamp the listing names, viscosity, hardness and total weight. Nothing was cured for this guide. Low viscosity resin, around 2000 cps where a figure is given, runs into small molds; none of these listings is a thick doming formula. Tack-free, low odor and anti-yellowing statements are the makers' claims and are reported that way. None of the listings states a lamp wavelength; resin lamps work at 365 to 405 nm, and a clear layer of about 2 mm takes 30 to 90 seconds under a UV-LED lamp or 2 to 4 minutes under a 36 W tube lamp. A thin tacky film on a hard piece is normal for many UV resins and wipes off with isopropyl alcohol. ## Picks ### 1.
