Alum is an ingredient in some recipes for homemade modeling compounds, often called "play clay" or "play dough", intended for use by children. [citation needed] Potassium alum was formerly used as a hardener for photographic emulsions (films and papers), usually as part of the fixer. It has now been replaced in that use by other chemicals.
Baking powder is made up of a base, an acid, and a buffering material to prevent the acid and base from reacting before their intended use. [5] [6] Most commercially available baking powders are made up of sodium bicarbonate (NaHCO 3, also known as baking soda or bicarbonate of soda) and one or more acid salts.
Play-Doh or also known as Play-Dough is a modeling compound for young children to make arts and crafts projects. The product was first manufactured in Cincinnati, Ohio, United States, as a wallpaper cleaner in the 1930s. [1] Play-Doh was then reworked and marketed to Cincinnati schools in the mid-1950s. Play-Doh was demonstrated at an ...
Yummy Dough was invented by Stefan Kaczmarek, an IT worker from Idstein, Germany, in 2005. [3] Kaczmarek credits his two daughters as having the original idea for the product because they "wanted to finally have dough they can play with as well as eat". [4]
Ammonium aluminium sulfate, also known as ammonium alum or just alum (though there are many different substances also called "alum"), is a white crystalline double sulfate usually encountered as the dodecahydrate, formula (NH 4)Al(SO 4) 2 ·12H 2 O. It is used in small amounts in a variety of niche applications.
It can be used to make ornaments and sculptures, and can be dried in conventional [1] and microwave ovens. [2] It can be sealed with varnish [3] or polyurethane; painted with acrylic paint; and stained with food colouring, natural colouring, or paint mixed with the flour or water. [1] Properly mixed salt dough does not crumble or crack.
Some additives, such as vinegar , salt , smoke and sugar (crystallization), have been used for centuries to preserve food. This allows for longer-lasting foods, such as bacon , sweets or wines . With the advent of ultra-processed foods in the late 20th century , many additives having both natural and artificial origin were introduced.
Examples of dough conditioners include ascorbic acid, distilled monoglycerides, citrate ester of monoglycerides, diglycerides, ammonium chloride, enzymes, [2] diacetyl tartaric acid ester of monoglycerides or DATEM, potassium bromate, calcium salts such as calcium iodate, L-cystine, [3] L-cysteine HCl, [4] glycerol monostearate, azodicarbonamide, [5] [6] sodium stearoyl lactylate, sucrose ...
