- feather-white, historical fibrous material, Feather white.
Meaning
The Delle report names feather-white as a material associated with a wick. The edition explains that the historical term was often used for fibrous mineral matter, but the particular substance is not specified in this passage. Its concrete appearance within an apparatus description does not authorise a definitive modern mineral identification. Retaining the unusual name is useful because a smooth substitution would hide the uncertainty of the supplied evidence. No fabrication instructions follow from its inclusion in this vocabulary register.
