When do you consider it turning color?

[drmac22]

When Testing say TA and you add drops until the color goes from green to red, when do you consider the last drop..? When the color is solid red and staying or when it turns slightly to red or when it flashes red then basically goes to clear or a very light green. With the CL test it turns clear and that is a very easy test to see. Just not sure about the TA. I have been counting drops until it turns slightly red and stays.

Once the color starts changing, you continue adding drops as long as the color continues to change. The final drop, which does not change the color any further, does not count.

To add a bit more, a shade change (light red to medium red, or medium red to barbie pink) also counts as a color change. No change means you add a drop and nothing happens at all.

Keep adding drops until the color stays the same for two drops in a row. Subtract the last drop and that is your total.

IE.....Drops 10 and 11 stay the same color. Your TA is 100.

Thanks! I was not quite adding enough drops. Should be a little more accurate now.

It also helps if you have the magnetic mixer. A lot less guessing.
