Vernice Bianca
Vernice bianca is a type of sealer varnish used in violin making. It is mainly prepared with a mix of egg white and gum arabic. The following is taken directly from American Lutherie #10 in 1987 when interviewing Jack Batts. It is also in The Big Red Book vol 1 from Guild of American Luthiers. A recipe for “Vernice Bianca” from Simone Fernando Sacconi 25g of gum arabic 1/2 teaspoon of honey 1/4 teaspoon of rock candy mbiguous termbr/> about 100cc of water albumen from one egg white. - Crush the rock candy - Warm the water but do not boil - Slowly add the gum arabic, stirring constantly until dissolved - Add honey and rock candy - Strain the mixture through a fine cloth (handkerchief or sheeting) and let cool While the mixture is cooling - whip an egg white into a meringue and turn the bowl on edge. - Allow the mixture to settle out and remove the liquid that separates.

Varnish
Varnish is a clear transparent hard protective coating or film. It is not a stain. It usually has a yellowish shade from the manufacturing process and materials used, but it may also be pigmented as desired, and is sold commercially in various shades. Varnish is primarily used as a wood finish where, stained or not, the distinctive tones and grains in the wood are intended to be visible. Varnish finishes are naturally glossy, but satin/semi-gloss and flat sheens are available. History The word "varnish" comes from Mediaeval Latin ''vernix'', meaning odorous resin, itself derived from Middle Greek ''berōnikón'' or ''beroníkē'', meaning amber or amber-colored glass. A false etymology traces the word to the Greek ''Berenice'', the ancient name of modern Benghazi in Libya, where the first varnishes in the Mediterranean area were supposedly used and where resins from the trees of now-vanished forests were sold. Early varnishes were developed by mixing resin—pine sap, for ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Violin
The violin, sometimes known as a ''fiddle'', is a wooden chordophone (string instrument) in the violin family. Most violins have a hollow wooden body. It is the smallest and thus highest-pitched instrument (soprano) in the family in regular use. The violin typically has four strings (music), strings (some can have five-string violin, five), usually tuned in perfect fifths with notes G3, D4, A4, E5, and is most commonly played by drawing a bow (music), bow across its strings. It can also be played by plucking the strings with the fingers (pizzicato) and, in specialized cases, by striking the strings with the wooden side of the bow (col legno). Violins are important instruments in a wide variety of musical genres. They are most prominent in the Western classical music, Western classical tradition, both in ensembles (from chamber music to orchestras) and as solo instruments. Violins are also important in many varieties of folk music, including country music, bluegrass music, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Egg White
Egg white is the clear liquid (also called the albumen or the glair/glaire) contained within an egg. In chickens it is formed from the layers of secretions of the anterior section of the hen's oviduct during the passage of the egg. It forms around fertilized or unfertilized egg yolks. The primary natural purpose of egg white is to protect the yolk and provide additional nutrition for the growth of the embryo (when fertilized). Egg white consists primarily of about 90% water into which about 10% proteins (including albumins, mucoproteins, and globulins) are dissolved. Unlike the yolk, which is high in lipids (fats), egg white contains almost no fat, and carbohydrate content is less than 1%. Egg whites contain about 56% of the protein in the egg. Egg white has many uses in food (e.g. meringue, mousse) as well as many other uses (e.g. in the preparation of vaccines such as those for influenza). Composition Egg white makes up around two-thirds of a chicken egg by weight. Water co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gum Arabic
Gum arabic, also known as gum sudani, acacia gum, Arabic gum, gum acacia, acacia, Senegal gum, Indian gum, and by other names, is a natural gum originally consisting of the hardened sap of two species of the '' Acacia'' tree, ''Senegalia senegal'' and ''Vachellia seyal.'' The term "gum arabic" does not legally indicate a particular botanical source, however. The gum is harvested commercially from wild trees, mostly in Sudan (80%) and throughout the Sahel, from Senegal to Somalia. The name "gum Arabic" (''al-samgh al-'arabi'') was used in the Middle East at least as early as the 9th century. Gum arabic first found its way to Europe via Arabic ports, so retained its name. Gum arabic is a complex mixture of glycoproteins and polysaccharides, predominantly polymers of arabinose and galactose. It is soluble in water, edible, and used primarily in the food industry and soft-drink industry as a stabilizer, with E number E414 (I414 in the US). Gum arabic is a key ingredient ...

Simone Fernando Sacconi
Simone Fernando Sacconi (May 30, 1895 in Rome – June 26, 1973 in Point Lookout) was an expert Italian violin maker and restorer who studied fellow ''luthier'' Antonio Stradivari extensively during his lifetime. "While still at school he became a workshop assistant to Giuseppe Rossi, a pupil of Degani. By the time he was 16, Sacconi already had his own clientele, and a particular ability as a maker of copies. In 1931 he moved to New York to work for the dealer Emil Herrmann. He continued to make new instruments – and occasionally bows – but his time there was mainly taken up with repairs and restoration work. In this field he had no equal, an example of his work being a Stradivari of the best period, virtually destroyed in an accident in 1948, which now shows no sign of having suffered. In the imitation of old Italian varnish he excelled all rivals. In 1951, upon the invitation of Rembert Wurlitzer, Sacconi went with his pupil D’Attili to work for Rembert Wurlitzer Co. A ...

Cremona
Cremona (, also ; ; lmo, label= Cremunés, Cremùna; egl, Carmona) is a city and ''comune'' in northern Italy, situated in Lombardy, on the left bank of the Po river in the middle of the ''Pianura Padana'' ( Po Valley). It is the capital of the province of Cremona and the seat of the local city and province governments. The city of Cremona is especially noted for its musical history and traditions, including some of the earliest and most renowned luthiers, such as Giuseppe Guarneri, Antonio Stradivari, Francesco Rugeri, Vincenzo Rugeri, and several members of the Amati family. History Ancient Celtic origin Cremona is first mentioned in history as a settlement of the Cenomani, a Gallic ( Celtic) tribe that arrived in the Po valley around 400 BC. However, the name Cremona most likely dates back to earlier settlers and puzzled the ancients, who gave many fanciful interpretations. Roman military outpost In 218 BC the Romans established on that spot their first military outpo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stradivarius
A Stradivarius is one of the violins, violas, cellos and other string instruments built by members of the Italian family Stradivari, particularly Antonio Stradivari (Latin: Antonius Stradivarius), during the 17th and 18th centuries. They are considered some of the finest instruments ever made, and are extremely valuable collector's items. According to their reputation, the quality of their sound has defied attempts to explain or equal it, though this belief is disputed. The many blind experiments from 1817 to as recently as 2014 have found no difference in sound between Stradivari's violins and high-quality violins in comparable style of other makers and periods, nor has acoustic analysis. The fame of Stradivarius instruments is widespread, appearing in numerous works of fiction. Construction Stradivari made his instruments using an inner form, unlike the French copyists, such as Jean-Baptiste Vuillaume, Vuillaume, who employed an outer form. It is clear from the number of f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
