Liminal Moment by Bobbette Rose - Encaustic Monotype on Paper. These are paintings done directly on a heated plate with pigmented wax. Paper is laid on top and the image is offset onto the paper, similar to a typical monotype but no press. She does sveral thin layers, each time laying the paper down on the heated plate. In the final stage she often paints back into the image with a oil paint and a brush. Japanese washi paper used for this process, then matt and frame them under glass.
Vibrant drawing by Ester Roi (http://esterroi.com/), made using coloured pencils. Roi uses what's called an Icarus Drawing Board technique where wax-based media (ex. coloured pencils, crayons, pastels, etc.) are used to draw a picture, after which the drawing is exposed to heat that softens and melts the wax, creating a visual effect similar to a painting.
