I did a batch of chartreuse x2 last night and I was thrilled. 2 reheats on the initial batch adding srpues and scraps with no darkening at all for the 6 injections I got. I was very happy with the results.
Today, however, I reheated the same batch and the color was noticeably darker.
This got me to thinking, does the colorant only get darker if you let it cure from the initial heating and then reheat it? Is it more important when using chartreuse to get all you want done in one sitting and not let the plastic cure overnight than other colorants?
Is there another colorant that does this so I know to make sure I get as much out of the batch as possible?
