According to Glen & Stephen Thistlewood, authors of an online article ‘It’s Krys-Tol Clear!’ at https://www.carnivalglassworldwide.com/krys-tol-glass.html, Krys-Tol glass, dates back to 1905.
The Thistlewoods further state that initially Krys-Tol glassware was made at the Ohio Flint Glass Company, and then later at The Jefferson Glass Co. of Follansbee, West Virginia, from around 1908 to 1918. In 1918, the Krys-Tol line was produced by Central Glass. I have no idea which company made this piece.
They also state that the glass was unusually brilliant (still is) allegedly due to high furnace temperature and a method of finishing and polishing the glass – and the trademark Krys-Tol was given to the range of glass made this way.
This pattern is actually named ‘Chippendale’.
This is a large sugar bowl that stands 4 inches tall without the lid. It is 7 1/4 inches from one outside edge of the handle to the other. The opening is 3 3/4 inches. With the lid on the piece stands 7 5/8 inches to the top of the finial. I have seen this piece referred to as a ‘Hotel Sugar Bowl’. Makes sense I guess.
The Thistlewood article also reports that this line was very popular in the U.K. I can see why, it IS an impressive looking piece.
