How to remove/dissolve Oasis wet floral foam? Problem: must be polyester friendly.
An art project involved sticking some glass rods into wet floral foam (that green stuff they put flowers in at the florist's), pouring polyester casting resin
onto the foam, and then letting it set. The desired end result was this:
\ | / <- Glass rods
\ | /
==\===|===/== <- Cast polyester plastic
\ | /
There was a release agent on the surface of the foam, but some plastic was able to travel down the glass rods into the holes they made in the foam. As a result, the lower ends of the rods (below the plastic layer) are coated in foam, which has been stuck to the rods via hardened polyester plastic.
The foam needs to go, since the glass and plastic all need to be clear. Is there a way to dissolve the foam without hurting the plastic? (The glass we're not worried about... unless you recommend HF. Which we won't use.) Right now we're planning to try and get the foam off mechanically, but that looks like it's going to be a big job.
(Floral foam is phenol formaldehyde
plastic, for what it's worth.)
