Hansen Glass


There are three Hansen brothers; Ronald, Robert and Richard; who all worked with glass. Ronald lived in Mackinaw City, Michigan. Robert (1922 - 2006) lived in Bridgeport, Michigan and San Diego CA. Robert and Ronald were the two brothers involved with iridizing glass.

The third brother, Richard Hansen (1931 - 1983), started the "Glass Twist" in Corning, California. He was a skilled neon sign maker, lampworker, and businessman. Arlene, his wife, operated the shop until 2005.

Ronald graduated from college with a major in chemistry. Ronald's knowledge of chemistry is what gave him most of the ideas and formulas for the great iridescence which he achieved. Ronald and his wife Dorothy started to experiment with iridescence in 1950. Ronald taught Robert how to iridize glass.
In 1960, Ronald started iridizing glass to sell, which was probably the true beginning of new carnival glass. Robert started about the same time. The two brothers never really worked together. Ronald's shop was in Mackinaw City, Michigan. Robert's shop was in Bridgeport, Michigan.

The Hansens did iridize some old glass. One example of a Northwood Grape & Cable tumbler with an N on it is known. Ronald iridized and signed it. There are other pieces of glass iridized by the Hansens made from old glass, but most of the Hansen Carnival was new glass. Most of the Hansen glass does have a pontil mark, but there will be a few that don't. Not all Hansen carnival glass is signed. Signatures were etched into the base of a piece. Robert signed his pieces "Robert Hansen" or "RGH". Ronald signed his pieces "Ron Hansen" or "Ronald E.Hansen".
The Hansens bought the glass which they iridized from companies such as Deganhart, Fenton, Guernsey, Imperial, L.G. Wright, Mosser, Smith, St. Clair, Viking and Westmoreland. To iridize existing glass pieces, the glass was heated almost to its melting point before being sprayed with the chemical salts. Many items completely melted before they could be finished, thus there was a certain amount of loss.

Reported health problems of both Ronald and Robert were said to have been partly due to breathing in of the materials that they sprayed on the glass, even though the fumes were vented outside. It has been said that both brothers moved to California for cleaner air.

Below are photos of many of the pieces that the Hansen brothers produced. Any item would have been produced in limited numbers and some are true "one of a kind".

The signature on this red turkey toothpick holder, shown on the left, is typical of Robert Hansen's signatures. It is a fluid and neat script done with an etching pen. The signature on this light amethyst turkey toothpick holder, shown on the right, is not the same. It looks scratched in the surface in a more haphazard way. While the piece on the right is a genuine Hansen item, the signature is probably not real.
The vase pictured above sold in May 2022 for $5,000 at a Burns Auction Services auction. It is six inches tall and red with beautiful iridescence. The bottom of the vase is inscribed "A rose for Rose." It is thought that Robert Hansen made this vase as a gift for Rose Preszncik and is thus considered a one of a kind piece.
