You can also use a one-ounce graduate cylinder to measure out 1/4 oz. of concentrate to make 8 oz. of working strength solution; or 1/2 oz.of concentrate to make 16 oz. working strength. If you do this, then after pouring the concentrate from the graduate into an 8 oz. or 16 oz. container, you should put some water into the graduate and shake it to dissolve the remaining syrup into solution, which is then added to the working-strength container. Do this several times, until you have gotten all the syrup from the graduate. This will ensure that you have the proper working strength. Just fill the container to the 8 oz. or 16 oz. mark to finish the brew, and mix well.(posted 8206 days ago)The advantage of this method is that you don't need to keep a stock solution. This helps to maximize the shelf life of the developer. It's easy, too.
