Dear Nicholas,

Thank you so much for your patience; I have finally heard back from my contact, who has worked with the Corning Glass Museum and the Museum of American Glass but who's personal passion is milk glass made around the world. He said he has never seen these marks either but confirms that they are European, circa 1900. It is almost certainly an assembled vanity set based on the varying marks. The greenish tint would be a factor of the ingredients in the glass - iron oxide and chromium are two chemicals that can give glass a greenish tinge.

Sadly, the market for milk glass is not very strong at the moment unless one has very rare studio art pieces by famous makers. Based on the photographs and information provided, and subject to examination, you have:

An assembled Continental milk glass vanity set
circa 1900, various makers marks
comprising:
a shaped tray (11 1/2 inches x 9), with "R" mark on the bottom.
a rectangular covered box (2 inches high, 4 1/2 by 2 3/4 inches), with mark "9" inside lid.
a shaped covered box (2 inches high, 4 1/2(?) by 4 inches), with a diamond "S" mark inside.
PROVENANCE: Inherited from a friend
$75-100 (represents a fair market value for auction purposes; retail or asking price may vary).

I am sorry the maker of these pieces remains elusive but that is often the nature of the antiques business. Please let us know if you have additional items to appraise, and thank you for using Mearto.
