Shellac is an American post-hardcore band from ChicagoIllinoiscomposed of Steve Albini guitar and vocalsBob Weston bass guitar and vocals and Todd Trainer drums and vocals and formed in Their music genre has been classified as post-hardcore   and noise rock  but they describe themselves as a " minimalist rock trio.
Shellac formed in ChicagoIllinoisin as an informal collaboration between guitarist Steve Albini and drummer Todd Trainer. Former Naked Raygun bassist Camilo Gonzalez sat in on early rehearsals and played on one song on Shellac's first single before permanent bassist Bob Weston, formerly of Boston 's Volcano Sunsjoined. Shellac has a distinctive, minimalist sound based on asymmetric time signaturesrepetitive rhythms, an angular guitar sound, and both Albini's and Weston's surreal, bitingly sarcastic lyrics.
Shellac's signature sound is often associated with their enthusiasm for vintage Travis Bean guitars, a rare brand of aluminium -necked instruments, and the Interfax "Harmonic Percolator" distortion pedal.
Albini is known to use copper plectrums and typically wraps his guitar strap around his waist rather than over his shoulder. The band prefers the intimacy of smaller clubs and live appearances are sporadic. Both Weston and Albini are recording engineers.
They prefer a sparse, analog recording sound with little or no overdubbing, and are meticulous about microphone placement and choice of equipment. Mid-set in many live performances Shellac take the time for one or more "question and answer" sessions, where members of the band respond in an off-the-cuff and, at times, jocular manner to questions shouted out by fans and hecklers alike.
Knowing that most of the audience had come specifically to see Shellac, the band went on first every morning as an incentive for the festival-goers to be up in time to see the other acts.Dahej gidc company list pdf
In AprilAlbini stated that a fifth Shellac LP was "just about finished" although it had "no projected release date". It would "most likely" feature nine songs and be released on Touch and Go Records despite the considerable downsizing that the label has undergone. From Wikipedia, the free encyclopedia.

Several cases of allergic contact dermatitis of the eyelids due to shellac in mascara and one report of contact cheilitis have been documented. Shellac is the purified product of lac, the red, hardened secretion of the insect Laccifer Tachardia lacca Kerr. This tiny insect sucks the sap of selected trees and bushes, and secretes lac as a protective covering.
The name lac is said to derive from lakhthe Sanskrit word for one hundred thousand, a reference to the very large number of insects involved in producing appreciable amounts of the product.
Lac is cultivated in India, Thailand, and Burma. The whitest lac is produced by insects infesting the kusum tree Schleichera trijuga. The harvester cuts twigs coated with lac into small pieces called sticklac. The crude material is ground and soaked in water to remove debris and insect bodies.Adjectives worksheets for grade 4
The remaining material is soaked in sodium carbonate, which removes laccaic acid, a complex mixture of at least four structurally related pigments. The resulting granules retain the yellow pigment erythrolaccin and are dried to form seedlac. Further treatment by melting, evaporating, or filtering yields shellac. Shellac is most often used as a finish for fine furnitures.
Further, the material has been used for almost years by the pharmaceutical industry. Examples of shellac's role in this field include: Tablet coating formulations, 3456 microencapsulation, 7891011 matrix formation, 12 enteric coating, 13 humidity tolerance, 14 and binding ability. Shellac is used in dentistry, as a binding agents for dentures, restorations, and mouldings, and for training purposes in dental schools.
Shellac has also been used as an ingredient in hair spray and in other cosmetics 2324 However, shellac undergoes an aging effect upon storage and thus has fallen into disfavor as an ingredient in some preparations.
The National Formulary XV recognizes 4 grades of shellac: Orange, dewaxed orange, regular bleached and refined wax-free bleached. The grades differ in the manner in which the seedlac is treated. Orange shellac is obtained by the evaporation of filtered ethanolic solutions of seedlac.
It may be dewaxed by further filtration. Regular bleached shellac is obtained by dissolving the seedlac in aqueous sodium carbonate at a high temperature. After filtration, a bleaching agent such as sodium hypochlorite is added. The resin is removed by sulfuric acid precipitation. Refined wax-free bleached shellac adds another filtration step to remove the waxes.Tales of xillia dlc pkg
The exact chemical composition of shellac is unknown. It appears to be composed of a network of hydroxy fatty acid esters and sesquiterpene acid esters with a molecular weight of about Aleuretic acid, r-butolic acid, shellolic acid, and jalaric acid are the major constituents.
The composition is a function of the source and time of harvest of the sticklac. Variability in the product may be a problem for commercial users of shellac. The physical properties of shellac also vary. Shellac is soluble in ethanol, methanol, glycols, glycol ethers, and alkaline water. A 1-year prospective, randomized, controlled trial was conducted to determine the ability of shellac to prevent infection and progression of dry gangrene to wet gangrene in 26 patients with type 2 diabetes.Medically reviewed by Drugs.Shellac, full set live Barcelona 04-06-2017, Primavera Sound sala Apolo
Last updated on Dec 7, Shellac is composed of hydroxyaliphatic acids and alicyclic acids. Shellac has been used in the pharmaceutical industry as a tablet coating, often for enteric coating on tablets.
In the cosmetics industry, shellac has been used in mascara, hair spray, nail polish and eyeliner. Traditionally, shellac has been used in the furniture industry as a wood or paint sealant. The median lethal dose for shellac has been found to be more than 5 grams per kilogram, many more times than what the average consumer might be exposed.
Toxicity studies in animals have shown no adverse effects from oral, dermal, ocular or respiratory tract exposure to formulations containing up to 6 percent shellac. Mutagenicity, irritation, sensitization and photosensitization were not seen in clinical analysis of cosmetic formulations containing up to 6 percent shellac. However, reports from note cases of allergic contact dermatitis in the eye area of those who used certain cosmetics, such as mascara. Final Report on the Safety Assessment of Shellac.

It is processed and sold as dry flakes pictured and dissolved in alcohol to make liquid shellac, which is used as a brush-on colorant, food glaze and wood finish.
Shellac functions as a tough natural primersanding sealanttannin -blocker, odour -blocker, stainand high-gloss varnish. Shellac was once used in electrical applications as it possesses good insulation qualities and it seals out moisture. From the time it replaced oil and wax finishes in the 19th century, shellac was one of the dominant wood finishes in the western world until it was largely replaced by nitrocellulose lacquer in the s and s.
Shellac is scraped from the bark of the trees where the female lac bug, Kerria lacca order Hemiptera, family Kerriidaealso known as Laccifer laccasecretes it to form a tunnel-like tube as it traverses the branches of the tree. Though these tunnels are sometimes referred to as " cocoons ", they are not cocoons in the entomological sense. This insect is in the same superfamily as the insect from which cochineal is obtained.
The insects suck the sap of the tree and excrete " sticklac " almost constantly. The least-coloured shellac is produced when the insects feed on the kusum tree Schleichera. The number of lac bugs required to produce 1 kilogram 2. The raw shellac, which contains bark shavings and lac bugs removed during scraping, is placed in canvas tubes much like long socks and heated over a fire.
This causes the shellac to liquefy, and it seeps out of the canvas, leaving the bark and bugs behind. The end-user then crushes it into a fine powder and mixes it with ethyl alcohol before use, to dissolve the flakes and make liquid shellac. Liquid shellac has a limited shelf life about 1 yearso is sold in dry form for dissolution before use.
Liquid shellac sold in hardware stores is often marked with the production mixing date, so the consumer can know whether the shellac inside is still good.
Some manufacturers e. Alternatively, old shellac may be tested to see if it is still usable: a few drops on glass should quickly dry to a hard surface.
Shellac that remains tacky for a long time is no longer usable. Storage life depends on peak temperature, so refrigeration extends shelf life. The thickness concentration of shellac is measured by the unit "pound cut", referring to the amount in pounds of shellac flakes dissolved in a gallon of denatured alcohol.During these challenging times, we guarantee we will work tirelessly to support you.

We will get through this together. Updated: August 13, Reader-Approved References. Shellac is a wood finishing product made by dissolving dried resin in denatured alcohol. Shellac was used heavily for finishing furniture during the 19th and early 20th centuries, and it is still available for use today.
The product is popular due to its ease of application, low odor, and all-natural origin. Shellac is non-toxic, and has even been approved by the United States Food and Drug Administration for use as a glaze for candies.

Learn moreShellac has been totally overhyped as a sealer. For about a hundred years, from the s to the s, shellac was the primary finish used for all coats by all small shops and factories. In the s shellac was replaced in factories by lacquer for two primary reasons: shellac resin from bug secretions is a commodity product that was going up in price as demand increased, while lacquer was going down in price; and lacquer thinner a blend of solvents makes lacquer much more versatile in different weather conditions.
Shellac continued to be used by painters and floor finishers working inside buildings and by amateurs until the s.
Then three things happened that almost totally ended shellac being thought of as a complete finish:. Shellac is much more difficult to use see below than these three finishes, so it almost disappeared as a finish except in a few niche markets such as French polishing and handmade reproductions of antique furniture.
Companies supplying ready-to-use shellac disappeared one after another until only Zinsser remained. Seeing its market disappearing, Zinsser Bulls Eyewith the help of some woodworking writers, turned shellac into a sealer, even introducing a dewaxed variety SealCoat that was marketed for use under polyurethane. But here we return to the central question: Why not use polyurethane itself as the sealer?
Why use shellac under several coats of polyurethane — or under any other finish? The answer is to solve a problem. Shellac has wonderful blocking properties, better than any other finish.
It blocks silicone contamination, which causes fish eye, odors for example, from smoke or animal urineand residual wax extremely well. Shellac also blocks the resin from pine knots and very oily exotic woods, which can slow the drying of lacquer and varnish significantly.
But notice that the first three situations are all refinishing problems, not new-wood problems, and the last is rare for professional finishers. Not only is there no benefit to using shellac as a sealer in most situations, there are good reasons not to use it. Shellac is a difficult finish or sealer to use.
The first reason is the confused naming. Before you even get started, you have to learn the different types of shellac. In liquid form there are clear actually pale yellow and amber shellacs. Should you be using that? Or will the shellac with its natural wax still included work just as well? In flake form, which you dissolve yourself in denatured alcohol, there are many more varieties: blonde, superblonde, lemon-yellow, orange, garnet, button, ruby, extra dark and more.
These names all refer to the color, ranging from pale yellow to very dark orange. A second issue is the way solids content is measured. Clear and amber liquid shellacs are three-pound cut. Dewaxed SealCoat is two-pound cut, which is no longer listed on the label. Though conversion to percent solids is possible so you can predict the total build of your finishthis is another difficulty you have to overcome.
A third issue is shelf life.To save this word, you'll need to log in. But adulthood means putting that sweet tooth in check. The numbers say no," 27 Feb. Alabama," 29 Dec. Send us feedback.
