Flame Paint

Flame paint is a new art form in Lavera, popular by many young free thinkers while disgusted by elderly and lawfulls.
It was discovered in the year 189 AP (by dwarfes) that you could make some stone change color by heating different alchemical compounds on top of it. While the use of a torch is enough the fire from a Fire Mage creates the best effect. Among young mages this artform has become popular to perform on rocks and mountains on the outskirts of cities. First the alchemical compunds are brushed on the stone after which it all is heated. Different combinations of alchemical compounds, heat and the length of time heated created different effect.
The compounds are not to hard to get hold of for spellcasters as they are regullary used in the brewing of potions. The rarest part of the compound is generally the magic itself and the time needed to transform the ingridients into its final form. That of both the young spellcasters have no problem of finding.
Ca 100 years in human cities
Most common: small cities around academia, the wrecked christoffer city, south elves. It has been known for much longer by dwarfes.
