Our custom milled borax is a super fine granule so it coats well without caking, and it has an additional 5% moisture added to it so it won't over dry eggs. Available in plain white, we also offer 4 HOT fluorescent colors. Steelheaders seem to prefer boraxed eggs, but borax is also becoming a very important additive when custom curing your eggs with either the Wizard, or Pro-Cure egg cure. Try adding a 1/4 cup to a 1/2 cup of white or colored borax to 12 ounces of egg cure. You will love the results.
