Warm water & Common table salt for a yellow flame
Warm water & Borax for a pretty Lime green flame
Warm Water & Rock salt or calcium chloride for an orange flame
Warm Water & Potassium Chloride for a Purple Color (Potassium chloride
Use just enough water to dissolve your coloring substance, then apply it to the log. If you'd like you can "paint" it on with an old paintbrush or pour it into the cracks of the log. You could even smear it on with a popsicle or craft stick.
Be sure to Dry your logs thoroughly and then add them to the fireplace for beautiful holiday fires.
