Encaustic is a type of painting that involves mixing warmed beeswax with pigment. It can be applied with brushes but is more often applied with metal instruments that are used to move the “paint” around to “sculpt” it, as the wax gives it a thickness or depth. This Icon was done with encaustic.
Ramekin is a small sized (usually round like a cylinder, but also sometimes oval) ceramic (most often) or glass dish that is used for serving certain foods and/or cooking certain foods directly in the ramekin, such as custard. Here one. This isn’t exactly a ten dollar word, except with the case of your average guy. If you send him into the kitchen to get a ramekin, this is more likely what he will think you meant. This, of course does not apply to @Josie and @incendiarydan and some of the other cooking fellows on Fluther. LOL.
I have no idea what the mystery word is that you guys keep betting on, I hope it wasn’t one of mine, somebody PM me and let me know what it is
