How the paste works with the solder used needs to be tested. I did. Wife makes 3D dream catchers using 4mm dia wire rings, in various diameters 6"-18" (all are coated) from craft stores. Rosin (or flux) core solder work ok but I've found this SOLDER-IT SILVER BEARING SOLDER PASTE used with solid LEAD FREE SILVER BEARING solder holds the best using a butane torch. Key is, one must heat what's being soldered after the paste is used and before the solder is applied. Temperature is everything. If the base material can be heated with a soldering iron by all means use it as the solder flows and bonds towards the base material. **Q: what type of metal is left behind?, silver?** A: I only used a small amount when I created a amethyst and sterling dragonfly for a client, still have quite abit of the soldering silver left. I used a low heat soldering iron (silver melts at a fairly low temperature) **Q: Could I use this on gold costume jewelry jump rings or will the silver look too obvious? I am at a loss as to what to use for the jump rings.** A: You could use it on the gold costume jewelry, however, it would be obvious it is not gold. You would better using Solder Paste With Flux Yellow Gold 14k 1 Dwt. ## Frequently Bought Together - Solder-It SP-7 Silver Solder Paste 7.1 Grams | Soldering Flux Paste for Electronic Components, Home Improvement, and Wiring | Silver Solder for Jewelry Making and Repair | Lead-Free Solder Flux - Aquiflux Self Pickling Flux for Precious Metals Gold Silver Jewelry and Hard Soldering 8 Oz Megacast (275 ml) - CRAFT WIRE 18 Gauge, 925 Sterling Silver Wire (Round) Half Hard Made in USA - 5FT --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/6940739-solder-it-sp-7-silver-solder-paste-7-1-grams](https://www.desertcart.be/products/6940739-solder-it-sp-7-silver-solder-paste-7-1-grams) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-07-24*
