Urchin Necklace with a Gemstone Centre
Materials & Tools List - UK
In addition to the tools and materials listed below you will need the following household items :
a small amount of oil and a paintbrush for making your moulds (I use olive oil but any culinary oil works well)
optional saran wrap/cling film to reseal any clay you aren’t using
deionised/distilled water to rehydrate dry/cracking clay
For torch firing you’ll need a timer (the one on your smartphone is perfect)
Fresh water for quenching
Scissors for cutting out your bail template
