What You’ll Need 10 ml of LabColor from Bramble Berry 8 ounces of warm, distilled water 8 oz bottle for storage Germaben Recommend Tools Mini Mixer Droppers Mini Funnel Thermometer ONE: Warm up 8 ounces of distilled water in a microwave safe container in the microwave for 30 seconds. We’re going for lukewarm, not scalding hot, so 30 seconds should do the trick. TWO: Take the cap off of the Labcolor and pop it in the microwave for 10-15 seconds. Do not over heat. If the glass gets too hot, it will break resulting in a very colorful microwave and an extra 20 minutes of clean up time added to the process. THREE: Carefully take the Labcolor out of the microwave. The glass may be hot so use a paper towel to hold the container. Put the cap back on and give it a good shake. Then pour the Labcolor into the 8 ounces of water. FOUR: Use your dropper to suck up some of the warm water and drop it back into the empty glass container. Shake the bottle again to make sure that we get all of the dye out of the bottle. Pour it back into the 8 ounces of water. FIVE: Use your dropper to add the Germaben preservative to the colorful mixture at 1%, which will be about 3 ml. IMPORTANT: Be sure that your mixture is below 140 degrees before adding the preservative to ensure effectiveness. SIX: Use the mini mixer to completely blend the Labcolor, warm water and preservative. SEVEN: Using a mini funnel or a super steady hand, pour the dye into a container for storage. Leave the lid off until cool to avoid condensation. EIGHT: Make sure to label the colorant. These are strong colorants making it hard to tell some of them apart once they’re diluted and bottled. I didn’t put a use-by date but 1 year from the time you mix is a safe use-by date.
