here’s another example of alcohol crazing.
I’ve known for a while that acrylic plus alcohol is supposed to lead to cracks/hazing, commonly referred to as “crazing”. I’d never actually seen it until now.
Here’s a cut piece of extruded acrylic.

Now I placed alcohol ink on it, thinking I might be able to get a stained glass effect. Like I said I had never seen crazing before, so I wondered if it were a myth. After about 20 seconds I noticed the cracks starting in from the edges.

The cracks were growing, slowly enough…
Seems to be more common with extruded acrylic.
@rbtdanforth cleans his acrylic with alcohol based hand cleaner I think, and never has crazing issues as far as I know. Whether that’s because of the type of alcohol or the type of acrylic isn’t exactly clear.
