What are Coatings?
For many years it was common practice to combine paraffin wax with chocolate to make a more durable chocolate for coating candy. A common ratio was 6 parts chocolate to 1 part paraffin. The FDA has since banned this practice, so an entire industry has evolved to produce coatings which don’t contain non food products. These generally contain vegetable oils and fats in place of cocoa butter which makes them less temperature sensitive and much easier to work with. Since these contain no cocoa butter or chocolate liqueur they are technically not chocolate by the legal definition although they look and taste just like chocolate. Coatings are available in a wide variety of colors and in dark, milk, white, peanut butter, and butterscotch chocolate flavor. Colors are white chocolate flavor.

This probably varies from one chocolate maker to the next, but the molds will not tolerate temperatures above 165 degrees F. so this temperature shoul
Coatings are layers of material added to glass surfaces to improve the performance of optics. They are primarily used to increase the amount of light that gets through the optics and into the eye. Without coatings, up to half of the light that enters the objective lens might never make it to the eye. Good coatings therefore mean a smaller objective can be used to gather the same amount of light and thus a smaller, lighter weight binocular can be used. Coatings also have other benefits such as improving contrast and reducing glare. You should be aware that not all coatings are the same. To carry the title of “coated”, optics only have to have a single layer of magnesium fluoride on one lens. To be “fully coated”, all lens have to be covered with at least one layer of coating.
