Is it Silk [Natural fiber] or is it Rayon [man made fiber] ??
How to Tell what is what!!
A Basic Guide by Military-Memorabilia
This info came from Ebay Guides-http://reviews.ebay.com/
One of the most basic methods of distinguishing original from replacement ribbons in a non-destrictive manner is to 'blacklight' them.  It is however, important to know what and how to do it properly.

 The first thing to know is specifically, what is a blacklight?  A blaclight is a light source specifically designed ro primarily emit near-ultraviolet light, along with a small amount of visible light in the indigo range.  Due to the nature of the light emitted, they produce virtually no illumination, unless yoo are very close to the source.  They come in two varities, flourescent and incandescent bulbs.  Both bulbs are characterized by the use of a deep blue-purplish glass envelope called 'Wood's Glass'.  While the incandescent bulb is a cheaper alternative to fluorescent bulbs, rhey are exceptionally inefficient at producing UV light (a mere few lumens per watt) owing to the nature of the incandescent light source.  It is for this reason that I recommend you invest in, and use flourescent blacklight bulbs for your ribbon testing, as incandescent bulbs, when producing so little UV radiation, may be unable to produce a true or visable test result.

  What does blacklighting do?  It has to do with the nature of the threads used in the production of the ribbon in question.  Natural material ribbons, such as those made of silk or cotton, are colored to the core by dyes.  Ribbons made with natural fibers are quite opaque in nature to UV light, and tend to appear flat or dark in color when exposed to an UV light source.  Artifical, or man-made fibers, such as nylon or rayon on the other hand, are literally plastic in nature, and are tranclucent to UV radiation.  What this means is, while the ultraviolet radiation itself is invisible to the human eye, illuminating certain materials with UV radiation prompts the visible effects of fluorescence and phosphorescence.  Most of us have seen the results of this at a Discothèque, when the DJ's switch from normal lighting to black lighting, and people's clothes begin to seemingly 'glow' like a neon bulb.

  Black light testing is commonly used to authenticate antiques.  To test your ribbon, turn off all sources of visible light.  Best results can be had in a darkroom, or any room during nighttime hours.  A ribbon that appears to glow or displays fluoresence is testing positive for the presence of artificial, or man-made fibers.  By knowing what the ribbon is made of, it can help you date it.  Artificial fibers generally became available after 1950, as production methods were refined to make their cost competative, or lower than natural fibers.  Nylon was invented in 1935, but its high-priority use in war munitions and parts make use as ribbon fiber a post-WWII reality.  And Rayon, while invented in 1855, the original production process was similar to producing nitroglycerine, which made the resultant fiber highly flammable!  A commercially viable and safe Rayon was eventually introduced in the mid-1930's.  As a general rule of thumb. pre-WWII - expect and accept only natural fiber ribbons on your medals.  WWII-Korean War era, artificial fiber ribbons are possible, but unusual.  Be sure to ensure the medal itself passes scrutiny!  Post-Korean War, artifical fiber ribbons became commonplace.

  Care in using blacklights:  Blacklights do emit a very small amount of UVA radation.  UVA is capable of causing damage to collagen fibers, so it does have the potential to accelerate skin aging and cause wrinkles. UVA can also destroy vitamin A in the skin.  UVA light can also cause DNA damage.  However, the strength of a black light in comparison to sunlight is minuscule, so it is doubtful that the periodic use of an UVA light poses any significant health risks. The weak output of black lights should also not cause DNA damage or cellular mutations the way sunlight can.  A greater concern in the use of blacklights is heat generation during use.  This is a particular concern when using incandescent blacklight bulbs, due to the inefficient way they produce blacklight.  For this reason, be sure to provide adequate ventilation to your blacklight source.



WWI Victory Medal Clasps
Army
 The U.S.Army authorized a number of clasps to be affixed to the ribbon of the WWI Victory Medal to denote service or combat in various fields or areas.  A listing of the various clasps, and the dates service qualified for the specific clasp is listed below:

COMBAT CLASPS
 A Combat Clasp is denoted by having a star at either end of the bar.  I have also included the number of days the particular battle lasted. and the number of KNOWN Divisions or Regiments involved.  A Regiment is roughly up to 5,000 soldiers, while a Division is approximately 15,000 soldiers.  This will give you a rough indication of the scarcity of each Combat Clasp listed.

Cambrai: May 20 to December 4, 1917                      (198 Days of Combat - 3 Regiments)
Somme Defensive: March 21 to April 6, 1918             (  16 Days of Combat - 1 Regiment)
Lys: April 9 to 27, 1918                                            (  18 Days of Combat - Units from 4 Divisions)
Aisne: May 27 to June 5, 1918                                  (    9 Days of Combat - 2 Divisions)
Montdidier-Noyon: June 9 to 13, 1918                        (    4 Days of Combat - 1 Division)
Champagne-Marne: July 18 to August 6, 1918            (  19 Days of Combat - 4 Divisions)
Aisne-Marne: July 18 to August 6, 1918                     (  19 Days of Combat - 8 Divisions)
Somme Offensive: August 8 to November 11, 1918      (  95 Days of Combat - 3 Divisions)
Oise-Aisne: August 18 to November 11, 1918              (  85 Days of Combat - 3 Divisions)
Ypres-Lys: August 19 to November 11, 1918               (  84 Days of Combat - 4 Divisions)
St. Mihiel: September 12 to 16, 1918                          (    4 Days of Combat - 13 Divisions)
Meuse-Argonne: September 26 to November 11, 1918  (  46 Days of Combat - 25 Divisions)
Vittorio-Veneto: October 24 to November 4, 1918         (   11 Days of Combat - 1 Regiment)
Defensive Sector: For participation in any 'minor' battle that is not honored with any of the above 'named' Combat Clasps:
     April 6, 1917 to November 11, 1918                       (584 Eligible Days - Typically for 1 Day of Combat - 2 Divisions, plus anyone engaged or wounded in combat)

SERVICE CLASPS
 A Service Clasp is denoted by not having stars on the ends of the clasp.  Again, the KNOWN number of eligible units are indicated).  Service Clasps were given basically "for being there".

England: April 6, 1917 to November 11, 1918 (References state ±30,100 issued)
France: April 6, 1917 to November 11, 1918 (12 Divisions - References state ±621,000 issued)
Italy: April 6, 1917 to November 11, 1918 (Support units from the 83rd Division - References state ±4,800 issued)
Russia: Any service in European Russia (3 Battalion to Regiment sized units from the 85th Division - References state ±9,000 issued)
Siberia: Any service in Siberia or Asian Russia (Volunteers from 5 Regiments - References state ±9,000 issued)

 The US Selective Service Records indicate 2,810,296 individuals were inducted during WWI, of which ±62,000 served in the US Navy.  As nearly 2,000,000 American servicemen in the A.E.F. (American Expeditionary Force) had reached Europe (primarily France) prior to the cessation of hostilities on November 11th, 1918, and the approximate issue of Medals with a Service Clasp (from above) was ±673,000, this means ±1,326,000 WWI Victory Medals were issued with one (or more) Combat Clasps, and ±748,000 were issued with no clasps, indicating stateside service only.

 Unlike the U.S. Navy and Marine Corps, the U.S. Army did allow the wearing of multiple Combat Clasps.  If an individual qualified to wear more than one clasp, the recipient was allowed to wear the clasp.  The exception being the wearing of a Service Clasp and a Combat Clasp.  A Combat Clasp is presumed to take precidence over a Service Clasp, so therefore, if anyone was authorized a Combat Clasp, they recieve that instead of a Service Clasp.  The most common way to upgrade to a Battle Clasp was to be awarded the Defensive Sector Clasp for being wounded.  This is what occured with my Uncle, who served with the 41st Division.  Since he was exposed to a gas attack (wounded), he became eligible for a Defensive Sector Combat Clasp vs a France Service Clasp.  Bottom line - any offering of a multi-clasp medal with Service and Battle Clasps combined are made-up combinations.  Also, the U.S. Army did not allow the wearing of multiple Service Clasps - if you were eligible for two Service Clasps, you only got to choose one for award and wearing.  That leaves the question of which combination of Combat Clasps are legitimate?  Not every clasp can be worn together.  Some are date exclusive, especially for Infantry or Marine units - you were either at one battle, or the other.  For example, you will never see an Infantry unit with the Oise-Asine and Ypres-Lys Battle Clasps together (however an Artillery unit, which spanned both battle fronts, DID recieve this unusual combination).

  The following is a list of the authorized clasps for the larger Army units raised during WWI.  Remember to add the Defensive Sector Battle Clasp mentally to every unit authorized any Battle Clasps.  If a unit was only eligible for the Defensive Sector Battle Clasp, then it will be the only clasp listed.  Also remember - this is a listing of UNIT eligibility.  For specific INDIVIDUALS, they would have had to participate in every specific battle honored with a Battle Clasp to earn the right to wear that clasp.

  With this knowledge, it is obvious that the most Battle Clasps an individual could have earned on any one medal is seven (by personnel in the 3rd Division, 6th Engineers).  Realistically, anything above three Battle Clasps is an outstanding accomplishment, by WWI standards.  With this list, you should have a start in identifing which unit the recipient of the medal with multiple clasps served in, as certian combinatons will only be found within certian units.  If a Battle or Service Clasp is UNIQUE to a unit - it will be denoted with a *U* following the name of the clasp.

 I have yet to find any specific unit authorized the England or Italy Service Clasps.  For Italy, however, it is most likely to be units from the 83rd Division in support of the 332nd Infantry Regiment.

* A sad commentary on the mindset of the times.  President Wilson and General Pershing had demanded all American units be kept under American command, much to the chagrin of our Allies who wished to piecemeal plug in American units as they arrived, wherever thay were "needed".  This is a precident that has continued to this day.  However, as a "colored" (read that as expendable) unit, the 93rd Division was "allowed" to be placed under French command for the duration of the war.  Because they were not under "American" command during the war, they were deemed ineligible for ANY clasp that would have been normally issued to any other unit, be it Combat or Service.  It is an inequity that has not been corrected to this day.

 Much of this information was consolidated from various internet sources, and the period reference "Battle Participation of Organizations of the American Expeditionary Forces in France, Belgium and Italy 1917-1918" by the US War Office, 1920.


The U.S. Navy and Marine Corps authorized a number of clasps to be affixed to the ribbon of the WWI Victory Medal to denote service in various fields or areas.  Unlike the U.S. Army, the U.S. Navy did not allow the wearing of multiple Naval clasps.  If authorized to be awarded two clasps, the recipient was required to choose one to wear with his medal.   Marines and Navy Medical Corps personnel attached to the Army in France earned, and were authorized to wear any Army clasps authorized by their parent command.  This has led to an exception to the prohibition on multiple bars for the Navy WWI Victory Medal.  Medals awarded to personnel in the Navy and Marine Corps Northern Bombing Group in France are frequently seen with the Navy Aviation clasp and the Army Ypres-Lys clasp together.  The possibility of another Navy WWI Victory Medal having multiple clasps is rare, as only 140 vessels qualified for two different clasps, and only two ships qualified for three different clasps.  But the individuals in these cases would have been barred from accepting more than one clasp due to regulations.  Most certianly, it would have to be a combination of the appropriate single Naval clasp (such as the Aviation, or possibly the Overseas clasp), and an Army battle clasp or clasps.  The first 18 clasps were authorized in 1919, and general distribution began in 1920.  The following is a listing of all authorized clasps, and how many were authorized:

Atlantic Fleet - 43,185
Transport - 33,505
Armed Guard - 22,381
Aviation - 15,000
Escort - 20,381
Destroyer - 10,000
Sub Chaser - 8,451
Grand Fleet - 7,500
Overseas - 7,500
Patrol - 7,500
Mobile Base 3,646
Mine Laying - 3,294
Mine Sweeping - 3,294
Submarine - 3,294
Asiatic - 1,000
White Sea - 1,000
Naval Battery - 817
Salvage - 817
West Indies - Number Uncertian - Authorizatization and distribution began in 1921

 Two clasps, the Hospital Ship, and the Gunboat clasps were mentioned in the original orders for the medal, but were never authorized for award.  Several other clasps, strictly unauthorized, and privately made and affixed, have surfaced on the Navy WWI Victory Medal.
 All of the clasps were represented by a bronze star when the ribbon bar was worn - a minature of the clasp was never used.  In addition, a Silver Star could be worn on the ribbon of the medal or ribbon bar for a citation of gallantry not justifying an award of the Medal of Honor, Navy Cross, or Navy Distinguished Service Medal.  This Silver Star Device was the genesis of the future Silver Star Medal, and all personnel recieving the Silver Star Device were authorized to trade that award for the Silver Star Medal when it was authorized in 1932.  A final ribbon device, a bronze Maltese Cross, was authorized for any individual attached to the American Expeditionary Force, but were not authorized to recieve one of the Army battle clasps.  It may be possible that the Maltese Cross device might be found with one of the Army service clasps, but the Navy authorization for these clasps was slow in coming (the Russia and Siberia clasps were authorized for wear in 1933; and the England, France, and Italy clasps were authorized in 1940), and the eligible recipient would have had to apply for the newly authorized clasp.
