Impasto Wax: Enkaustikos blends their highest quality pharmaceutical grade beeswax with a pure translucent white microcrystalline wax to produce Impasto Wax. Impasto wax allows artists to inexpensively add actual dimension and sculptural effects to encaustic paintings. Encaustic painters often use Impasto Wax when doing the 'Slip and Score' technique that is common in ceramics. This technique refers to the method of scoring or scratching lines into the surface of a chunk of wax that will be attached to the substrate, dipping the scored side into the molten impasto wax, and sticking it to the substrate. Facts on Microcrystalline Wax: Enkaustikos utilizes a high quality microcrystalline wax that is essentially, a complicated carbon based wax characterized by branched, cyclic chains. This allows it to blend better with beeswax and oil colors than paraffin waxes which are only simple, straight carbon based chains. Microcrystalline wax is also more flexible than paraffin making it ideal for building up layers of textures. and ensures the integrity of your paint film. Microcrystalline wax melts at a higher temperature (170 to 180 degrees F) than Enkaustikos paints and beeswaxes (143 to 150 degrees) allowing you to apply encaustic paint over the modeled surface with minimal disturbance to the bottom sculpted surface. Microcrystalline wax will yellow over time from exposure to UV so it is very important to paint over and encapsulate the impasto wax layer.
Extra Precaution: Microcrystalline wax is a petroleum-based wax, which will give off vapors in the molten stage. Therefore extra consideration should be taken to provide proper ventilation within your studio.
