[quote="john_s"]What a great article. It's time for me to mix some up and try it. One part of the mixing instructions I was not sure of, mixing part B. When you say that the "The total amount of solution will be slightly in excess of 1300ml" does that mean that the instructions for part B actually make 1300mL?

In other words, if I want to make 1000mL of part B should I use 769g of potassium carbonate?

Most formulas end with "water to make 1000mL"

Thank you for alerting me to this matter.

This part of the article is confusing and will I will see that it is changed as soon as possible. With the Stock Solution of Pyrocat-HD we should start with 1000ml of water and slowly add to the water 1000g of potassium carbonate. This will make a total amount of Stock B solution of approximately 1300ml. Previously published formulas made this step clearer but I can see that there could be some confusion with the directions as provided in the article.
