..guess it should be "van Dijk", since it's an originally a dutch
name..;-)..
prints were less permanent than other types of Alternative
Processes.

..I read somewhere that a cyanotype image is more stable than the paper
were it's sitting on.. VDB is reported to be less stable..but again these
"quotes" from my memory, could be totally wrong on that. From my own VDB's
and cyanotypes I can only tell you that the oldest one is still stable
..(taht is : 6 months old...:-)...
