Ammonium Carbonate (Baker`s Ammonia), Food Grade, 1 Lb. Cookies
Ammonium Carbonate (Baker`s Ammonia), Food Grade, 1 Lb. Cookies, Leavening agent Our food grade ammonium carbonate (aka Baker’s Ammonia) consists of pure ammonium carbonate. Also called for in baking recipes as “Hartshorn Salt”. It is popularly used as a leavening agent for flat pastries. Useful note! Crush to use as smelling salts to revive a fainted person. Ammonium carbonate is mainly used as a leavening agent in traditional recipes, particularly those from northern Europe and Scandinavia. It can sometimes be substituted with baking powder, but the finished product will never be as airy and light as the original recipe. Icelandic loftkokur (air biscuits) for instance require leavening by ammonium carbonate. SPEKULATIUS – AMMONIA COOKIE Makes about nine dozen three inch sized cookies. 4 c. sifted all purpose flour 2 c. sugar 4 tsp. cinnamon 1 tsp. salt 2 tsp. Baker’s Ammonia (ammonium carbonate) 1 c. butter 3 eggs, beaten 2 tsp. lemon zest 1 egg white 1 tbsp. water 1/3 c. sugar (to sprinkle) Sift flour, sugar, cinnamon, salt and Baker’s Ammonia into large bowl. Cut in butter with pastry blender until mixture resembles coarse crumbs. Mix in eggs and lemon; chill. Roll dough 1/8 inch thick on floured surface; cut with cookie cutters; placed on greased cookie sheets. Combine egg white and water; brush over top of cookies; sprinkle with sugar. Bake at 375 F for 8 to 10 minutes. Chemical Formula: (NH4)2CO3 Appearance: White powder Chemical Grade: FCC/USP (Food Grade) Quantity: 1lb CAS Number: 506-87-6

Scrap Gold Recovery Kit, 500g Sodium Metabisulfite and 500g Urea
Gold Recovery Kit, 500g Sodium Metabisulfite and 500g Urea, Gold Refining Kit, Scrap Gold Recovery This kit is a convenient way to obtain some of the chemicals used in scrap gold recovery. General instructions are included giving a short overview for performing gold and other precious metals precipitation from aqua regia solution. Links to more in depth websites are also included. Sodium metabisulfite is commonly used to precipitate dissolved gold out of aqua regia and gold chloride solutions. When it is dissolved into water, sulfur dioxide gas is created which is excellent at precipitating gold from the solution. Sodium metabisulfite is a popular choice in this process because it is more selective in precipitating gold by itself. In the process of gold extraction from e-waste and scrap gold recovery, Sodium Metabisulfite is usually used along with Urea. Urea, also called carbamide, is soluble in water and alcohol and is non-combustible. In gold recovery processes, it is used as a neutralizer of excess nitric acid in aqua regia solutions. To make aqua regia solution you will need concentrated hydrochloric acid and concentrated nitric acid (for nitric acid, please see sciencecompany.com). These chemicals are sold separately from this kit.
Potassium Ferricyanide, 500g, Cyanotype photography, Blueprint
Potassium Ferricyanide, 500g, Cyanotype photography, Blueprint Potassium Ferricyanide appears as bright red, lustrous crystals. Soluble in water, slightly in alcohol. Uses include production of pigments, cyanotyping, laboratory reagents and electroplating. The compound itself has low toxicity but decomposes on strong heating to evolve highly toxic fumes.
