[Sca-cooks] My last post on pysanky and vinegar

My pardon for this further digression from food topics, but Rhiannon Cathaoir-mor
 said a few things that piqued by curiosity:

Have you done acid etching using period methods on different materials or
different art forms? Metal perhaps as well as eggs? I think an overview
article on period acid etching of different materials or how it was used for
different crafts would be interesting. We have discussed making vinegar here
before and how the period stuff might have differed in acidity. Was vinegar
the only acid solution they had available and used? I'd certainly like to have
a good article on these subjects for the Florilegium. And/or it might make a
nice arts & science project.
