Re: Short Duration
- Carol (and ALL)-
Try covering your bath with old newspapers after your day's run of
marbling. Then remove them the next day...or whenever. The ink from the
newprint seems to have a wonderful antiseptic quality to it and keeps the
size fresh MUCH longer. Most presses are now using soy based inks, but they
still work well. My favoite is the New York Times....about two weeks old.
