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. For example: a 1-lb. cut of shellac is the strength obtained by dissolving one pound of shellac flakes in a gallon of alcohol (equivalent to 120 grams per litre). [13]
Nitrates (when mixing with aluminium, boric acid should be added as a stabilizer): Potassium nitrate – very common, used in black powder and wide variety of compositions. Not very hygroscopic. At lower temperatures (with ordinary fuels like rosin or shellac) not very efficient, does not burn well, produces potassium nitrite.
The word lac is derived from the Sanskrit word lākshā '(लाक्षा) representing the number 100 thousand, which was used for both the lac insect (because of their enormous number) and the scarlet resinous secretion it produces that was used as wood finish, lacquerware, skin cosmetic, ornaments and dye for wool and silk in ancient India and neighbouring areas.
The conservation and restoration of lacquerware prevents and mitigates deterioration or damage to objects made with lacquer.The two main types of lacquer are Asian, made with sap from the Urushi tree, and European, made with a variety of shellac and natural resins.
Resinous glaze is an alcohol-based solution of various types of food-grade shellac.The shellac is derived from the raw material sticklac, which is a resin scraped from the branches of trees left from when the small insect, Kerria lacca (also known as Laccifer lacca), creates a hard, waterproof cocoon.

The materials used to wax produce depend to some extent on regulations in the country of production and/or export. Both natural waxes (carnauba, [12] shellac, beeswax or resin [4]) and petroleum-based waxes (usually proprietary formulae) [3] are used, and often more than one wax is combined to create the desired properties for the fruit or vegetable being treated.
1000 Hurts is the third studio album by American rock band Shellac, released on August 8, 2000. In its official promotional materials Shellac jokingly described this album as follows: "There are no 12-minute songs on this one. This record is more mean-spirited. Todd sings." The cover is a clear homage to old Ampex audio recording tape boxes ...
In chemistry, a regular solution is a solution whose entropy of mixing is equal to that of an ideal solution with the same composition, but is non-ideal due to a nonzero enthalpy of mixing. [1] [2] Such a solution is formed by random mixing of components of similar molar volume and without strong specific interactions, [1] [2] and its behavior ...
