Reinhold Schlegelmilch produced what collectors consider to be R.S. Prussia (RSP) in his factory from the late 1800s through World War I. These pieces marked "R.S. Prussia" in red lettering surrounded by a green wreath were made at the turn of the last century. This is sometimes referenced as the "red mark" by collectors, and it remains the most popular and recognized mark among fans of this type of porcelain, although a number of others were used.
It is also good to know (according to the International Association of R.S. Prussia Collectors website) that most of the historical information on this type of porcelain published prior to 1994 appears to be largely inaccurate. Reinhold and Erdmann Schlegelmilch were long thought to be brothers jointly operating one factory, but they actually ran two different factories located in Suhl, Germany in direct competition with one another. Collecting organizations often continue research for years ferreting out truths and discarding inaccuracies, which is another good reason for joining up with them to exchange information whenever possible and utilizing the resources they provide .
Condition Factors to Consider
Despite all the controversy over the history, when you think about the age on RSP pieces, with most being around more than 100 years now, these treasures have held up extraordinarily well.
Still, all pieces need to be checked for damage before they are purchased as there are a number of porcelain pitfalls to be aware of.
Knobs on coffee pot lids, teapots, and sugar bowls should receive a thorough inspection as prime candidates for being re-glued after being broken off. Running a finger along bowl edges, plates, and pots will detect any rough spots where chips and less severe "chigger bites" may be hiding.
Holding pieces to the light can indicate cracks and glues used in repairs. Some people even carry a pocket-sized black light along while shopping to help detect repairs since the glue will often fluoresce when held under ultraviolet light.
Just because a piece has been repaired, especially if it's a rare item, doesn't mean it shouldn't be purchased. However, the quality of the repair should be considered when determining value. Only pieces with professionally applied repairs should bring top prices in the secondary marketplace.
Evaluating the Quality and Desirability of R.S. Prussia Pieces
When considering the desirability of R.S. Prussia, don't forget to evaluate the way it is decorated and the quality of the porcelain. Some RSP pieces were more carefully decorated than others. To fetch top value, this porcelain should be delicately crafted and finely finished.
Floral decor, generally considered more common, doesn't command as much attention as pieces featuring portraits, animals, classical, and scenic themes.
In addition to beautiful decorations, various finishes adorn many RSP pieces. Some have "jewels" decorated to imitate opals, others have a finish similar to the iridescent look popularized by Tiffany and Co. Lavish gold embellishments enhance many of the gaudiest, and most popular, RSP pieces.
Evaluating the various mold shapes is another interesting aspect of learning about this porcelain. Molds used vary from simple to extremely ornate, and with most avid collectors, the fancier the better. Blown out flowers, ornately shaped handles and spouts, and beautifully curving finials all add to the appeal of RSP. Chocolate pots with matching demitasse cups and dresser items such as hatpin holders and hair receivers were all made by the Schlegelmilch factory in addition to the more common bowls, plates and creamer and sugar sets most frequently found.
Identifying R.S. Prussia Reproductions
As with most expensive and popular antiques, there are reproductions being passed off as genuine R.S. Prussia. It's wise to handle as many genuine pieces of R.S. Prussia as possible to get a feel for the real thing. When identifying RSP repros, look for:
- Heavy, thick porcelain in comparison to the delicate nature of most R.S. Prussia.
- Items decorated plainly with modern-looking floral decals and a lack of hand painting.
- R.S. wreath marks that omit the word “Prussia.”
- Mold shapes never produced by the RSP factory that have wreath marks similar to those found on genuine pieces.
Valuing R.S. Prussia
R.S. Prussia pieces have appreciated handsomely since the 1970s when folks really started taking notice of these pieces. Portrait pieces purchased for $200 back then are easily worth $1,500 or more now. Even the more common and less popular floral decorated pieces are generally worth $75 or more, and they can be worth much more depending on the mold used to fashion the piece and how elaborately it is decorated.
Values for More Simple Lines
Those preferring simpler lines can also find RSP examples to suit their taste. Some of these pieces can be pricier than the ornate items, depending on the theme. A plain vase with a lion and tiger motif could have been marketed for $10,000 to the right collector in the past. Prices have leveled off for these items now, although these pieces are still considered rare and valuable. The same type of vase with floral decor would probably sell for for far, far less, even when marked.
Valuing Unsigned R.S. Prussia
A number of unsigned pieces also left the factory. Learning to recognize these can offer the most bargain potential for thrifty shoppers and dealers looking to make a profit. While signed pieces generally hold more value, especially with common floral pieces, unsigned RSP decorated with portraits and other highly desirable motifs still bring high prices. The same holds true for extra fancy mold shapes.
