Protecting Gemstones With Kool Jool When Sizing Rings

@flowmke2 uses Kool Jool gel to isolate a gemstone from torch heat when resizing a ring. It also acts as a heat sink.

Here is another technique to protect a gemstone during a repair or sizing from @flowmke2 - “It’s not foolproof, but a protectant like this #KoolJool can isolate gemstones from torch heat for resizing rings. This is a 20mm chalcedony. The gel is also a heat sink - it took a long time for solder to flow” thank you so much for allowing me to share this! 🙌 I’ve never worked with KoolJool but I’m definitely curious to hear about everyone’s experiences!! #metalsmithsociety #jewelrytools #solderingjewelry #jewelryrepairs
