What I love about the process is that it seems to have developed by playing with fire.
Also known as experimentation, which is the whole basis of the scientific process.
There isn't.
Referring to experimentation as "playing with" feels like a attempt to demean the output.
Or someone melted down a glass and gold object and noticed the gold that floated (precipitated?) out was purer than that which went in.
Even today various artists playing with fire rediscover that while gold doesn't naturally work into or onto glass it's still possible to adhere gold to glass if the timings and tempreptures are "just right".
