OPAL TERP GEMSTONES

Opal terp gemstones are set opal rather than worked glass, which means they hold heat considerably better than borosilicate marbles and throw genuine colour play as they turn in the bucket.

The heat retention is the practical argument: an opal that stays hot keeps working through a longer dab where a glass marble has already cooled.

Specs

• Set opal terp gemstones
• Better heat retention than borosilicate
• For use with quartz bangers
• Requires a carb cap to spin

Care

Remove while warm and wipe gently. Avoid long isopropyl soaks with set opals; wipe clean rather than submerging.
