Alpaca - also seen as Alpaka, Nickle Silver, German Silver. Possibly abbreviated ALP. Not really silver, this is an alloy, usually of copper, nickle, zinc and/or tin. May contain a small amount of silver (about 2 percent). Can be used as a base metal for silverplating. May also be used as a silver look-alike without being plated.|
'Footed salt' style - I'm using this term to denote ships that are on some type of base, usually holding the actual ship part up off the surface upon which it sits (not counting the small rim at the base of many viking ship salts). This is accomplished in several ways, including small posts (usually 4); supports that are designed to look like feet; a base designed to look like waves; or one or two crossbars attached to the ship (ships with crossbars often have supports curving out and down from the lower part of the front and back of the ship, also).
H&J - The book 5,000 Open Salts A Collector's Guide by William Heacock and Patricia Johnson. Original copyright 1982, reprinted 1995 (and possibly 1998). Although this book contains only 16 different viking ship style salt cellars, it's still a good reference. The prices and availability information (1996-97 Rarity and Price Guide) are a bit outdated, however, since it seems that the internet and online auction sites such as eBay have changed collecting a great deal. One drawback of H&J is sometimes indistinct pictures, and lack of detailed information, especially on makers marks. Update: I have learned that there is an updated 2002-03 Rarity and Price Guide, but I do not have it yet, so I don't know how much (if any) the listed values for any of the viking ship salts have changed.
HÅNDSTØPT - handcast (in Norwegian).
Master salt - a large salt cellar (or larger version of a small salt cellar). Intended to serve either as the salt cellar for the entire table, or as the main salt container, from which smaller, individual salts were filled.
NORGE - Norway (in Norwegian, Danish and Swedish).
Plique à Jour - a technique of creating an object with open spaces (using filigree or piercing the metal), then repeatedly filling the spaces with special enamels and firing. The enamels are translucent, allowing light to shine through, creating a beautiful 'stained glass' effect.
Prow or Bow - the front of a ship, and Stern - the rear of a ship. Some viking ship salts have a different prow and stern to the design, and in others, the prow and stern are identical.
Silver - this isn't as easy as it sounds. There are several grades and types of 'silver'.
Sverige - Sweden (in Norwegian, Danish and Swedish).
TPB - a marking on items made by a company that may have once been in existence in Bergen, Norway. Still searching for more information.
TINN - Pewter.
Unidirectional and Bidirectional - these are my own terms, referring to the shield placement on the viking salts.
