Baking soda can be used to instantly set super glue. The problem is, the result dries or hardens in a transparent form, making it hard to know if you have enough glue where you want it. It also makes it hard to know when you have sanded enough.The solution? Dye your baking soda! You can use inkjet or technical pen ink to dye several batches of baking soda. You can make different colors this way, too. Let the colored piles of dyed baking soda dry overnight, then break up the clumps and store the baking soda in “ready service” containers of some sort – old 35mm film containers or sturdy airtight bags work well.When you sprinkle some of the dyed baking soda onto liquid super glue, it will instantly harden in an opaque color. The chief benefits of having different colors are that you can see some colors better against certain plastics or resins, and you can layer the colored baking soda to fill seams so you can see what you already sanded down and what has recently been added over the top of that. The colors will darken as they set; you may want to consider that when you dye your soda.
