You may want to purchase a speed stir. That is real helpful in mixing the drops as they are added.I'm following the FC test steps but in some of my prior tests the sample does not go colorless and remains a very faint pink color even after many R-0871 drops. Would a very faint pink color be considered colorless or not? Let's see how the test goes tomorrow morning. Thanks everyone.
