Carnival glass

Both functional and ornamental objects were produced in the carnival finish and patterns ranged from simple through geometric and 'cut' styles to pictorial and figurative.

Iridill was inspired by the fine blown art glass of such makers as Tiffany and Steuben, but did not sell at the anticipated premium prices and was subsequently discounted.

The final (post doping) surface shades also vary according to the depth of base colour, as well as any special treatments and the type and amount of salts used.

This happened most frequently in early production but to such an extent that collectors now differentiate between these items, describing the degree of iridescence showing.

The final surface colours of marigold are mostly a bright orange-gold turning perhaps to copper with small areas showing rainbow or 'oil-slick' highlights.

Marigold carnival glass is the most frequently found colour and in general commands lower prices in the collector market.

In smaller numbers and less often found are items to do with lighting or associated with smoking and those designed solely for show as ornaments such as figural sculptures or statuettes.

By selling sample pieces to carnival fair operators, it was hoped that a winner would then go on to purchase further items in the same or a similar pattern.

Of their non-figural production, the strong, bold and easily recognizable 'African Shield', 'King James' and 'Drape' patterns provided a good canvas for shimmering carnival colours.

However, the most distinctive continental European patterns are probably the similarly styled 'Classic Arts' & 'Egyptian Queen', produced by the Czech Rindskopf works, sporting stained bands of figures over a very simple geometric form in a very even marigold.

Identifying carnival glass involves matching patterns, colours, sheen, edges, thickness, and other factors from old manufacturer's trade catalogs, other known examples, or other reference material.

Since many manufacturers produced close copies of their rivals' popular patterns, carnival glass identification can be challenging even for an expert.
