The multicolored spatter glass decors have a unique rendition

in the Rückl glass family of Art Deco decorative pieces. It's an

excellent way to judge what is different about Rückl decorative

glass items, compared to it's export competitors, especially

Kralik.


There is are common elements to this spatter decor and the

choice of colors found on each piece, which were carefully

crafted. They may have been applied in various ways while

hot at the furnace site: pulled, or big applied glass chunks with

smaller chips, often on the same glass piece or seen on different  pieces. 


Yet, what matters is the colors of the glass, and the fact that they are exactly the same shade every time. This can be ascertained with glass in hand. It is a lot more difficult to identify glass decor colors with images which may have been modified by different lighting conditions or photo edit options. I can promise you that once you have a a few pieces in the same color range, which vary from prominent red to green, yellow, orange, pink and blue. When taken together in a single picture, you can't modify the fact that the glass colors chosen match. If you consider that the colored glass canes used for fabrication may have had a range of 25 different reds, 25 different greens, 25 different yellow, etc. then it's understandable how an exact match of several colors together on one piece is extremely significant, and can be confidently used as a provenance and attribution tool result of the glass items.


This is instantly visible when you see my first image with the grouping of glass pieces, with the missing blue color prominent spatter blend. Along with these colors, you should note that each variation has two exact colors that are repeated in each one, pale gray-blue and pale rose-pink glass chips. Other colors may appear as well due to the application of two layers of glass chips which form the core of the spatter decor. This can be detected by looking at the same inside and outside area which looks different. What also happens, is due to the heated glass process, some color chips melt into one another, for instance dark blue and yellow will form a third color, a green of varying intensity. These are the unpredictable effects which makes each spatter glass piece unique in some way. I have several other Czech glass makers in my collection and NONE have a four layer glass fabrication with the colored chips layers in the center of the outer layers.


Fabrication is solid and heavy, I made a point of showing the width of the cut upper rims in my close up images, so you can see the two layers of clear glass applied to the inside and outside surfaces, with the heated two core layers of spatter color chips in between. Another aspect is the size, Rückl produced larger, heavier pieces of decorative glass for export. This instantly makes them more expensive to ship and will demand a higher price at retail, in Europe or overseas. For instance, the pink posey jar is 5 inches by 5 inches, the orange with black pedestal foot is 7 inches high, the red, green, yellow, and orange vases are 8 inches to 11 inches high, the orange and yellow lidded boxes are 6 inches by 6 inches.

MY COLLECTION I: THE MULTI GLASS COLOR SPATTER DECORS & pink and blue accents.

This peloton (yarn ball) glass decor continues to evolve as more color variations and applications are discovered. I like to group similar colors together in one photograph, with light and shadow accenting the tones and hues, where you can see that these originated from the same choice of colored glass rods.


This is what I see when my collection is displayed together, and confirms to my eye that I am looking at the same manufacturer's decorative glass items.


​This is also instrumental in seeing difference with other Czech maker's colored glass pieces, even if they are subtle. The orange and yellow colors have the whole color wheel represented at times. Yet, it becomes evident that the production was made with specific color rods, here, we see a Rückl cool yellow, which may look greenish under certain light conditions, a red which is not a true red, but a warmer shade in the coral range, the orange is a true medium orange color.


There are more peloton decors in a light blue background with red and yellow strands, a medium green background with black and yellow strands, and a yellow background with red and green strands. The application of the pulled strands also varies, from short to very long lines, from dense to sparse, from heavy to slight and faint. See my slide show pages for more images.


I am including again a few close ups, two of these pieces have the white oval MADE IN CZECHOSLOVAKIA mark, and the glass is fabricated with thick multi layers of glossy clear glass, and a double layer of background spatter with the applied peloton glass chips.

THE PELOTON Decors - The Yellow, Orange, Red, & Dark Blue Glass Variations

For this section: a study of the prominent yellow and orange glass chip colors used.


The purpose here is to compare the true colors of this glass, something than can be determined easily with glass in hand, but much more difficult with images, unless the glass items image have been taken together. 

You will note I am using the Rückl orange spatter decor for this purpose, I start with 4 items with matching yellows and oranges, plus the other shades that are consistently part of this particular mix. The pale blue, pale rose, cobalt and dark green glass chips.The Rückl yellow, which is a cool true yellow, the Ruckl orange, which is an apricot orange, the Rückl red, which is a deep warm coral red glass color. In my collection, these tones are consistent from glass piece to glass piece, no matter what the decor is.

A look at the Butler Brothers Wholesale ads for some Ruckl glass vases, dating February 1929 and February 1930, catalog page inserts from the St. Louis and New York warehouse goods. I include the ad which describe two groupings of 12 vases, in 12 different styles (meaning shape) and all with a cased decorative spatter décor or other. At the time cased was a term used for glass which had more than one layer. The height is given as 7 7/8 inches and 8 inches, but as these glass pieces were hand cut after cooling from the hot furnace molding, it is one of the slight variations, where you can find a range of slightly higher and slightly shorter vases.
