Thanks to all those that have answered to my question.
It is up to now the first time that I prepare gum solution, it had used a
mark of paste, but they should have changed the formula because he/she no
longer works well.
I have decided to use 2 drops for oz of solution of carbolic acid to 15% as
preservative in this my first experience. If the mathematics don't lie, 200
ml. of gum solution they can be equal to 6.5 oz, with what I will put 13
drops of carbolic acid in my gum solution.
If it is not this way the calculation, please correct me.
