Bail
On the label: Bail · Finding and chain
What it is
The loop on a pendant that the chain passes through; a hinged bail lets a pendant go on an existing necklace.
Finding and chains: The working parts: clasps, posts, backs, jump rings and settings. A piece is only as good as its findings.
In the research
5 PubMed papers mention it with jewelry, allergy, eyewear or UV; the three most recent:
- Highly improved photocatalytic degradation of rhodamine B over Bi(2)Ga(4-x) Fe (x) O(9) solid solutions under visible light irradiation · RSC advances, 2019
- The Enhancement of H(2) Evolution over Sr(1-1.5x)Tb(x)WO(4) Solid Solution under Ultraviolet Light Irradiation · Materials (Basel, Switzerland), 2019
- Ionic liquid-based microwave-assisted extraction of rutin from Chinese medicinal plants · Talanta, 2010
A paper is a paper, not a verdict: titles are listed so you can read them, and a study on one fabric or one filter says little about the piece in your hand.
Other finding and chains
Clasp & Lens describes materials from the public record and does not appraise, grade or test pieces; what a listing states is the supplier's statement. If a piece causes a rash, take it off; a reaction that spreads or blisters is a doctor's question, and sunglasses are no substitute for impact-rated eye protection where that is required.
