How to cure Epoxies to make them food safe?
Even the best quality and food grade epoxies are not food safe if they are not cured correctly. Epoxy will contain: one bottle of resin and on bottle of hardener. It's should be mixed and applied in your epoxies in a warm space ( room temperature ). It will be different to mix epoxy when it's colder than about 70-75 degrees. It's recommended to apply epoxy in two coats, a thin seal coat to prevent air bubbles from rising later, and a thicker coat ( poured on once the seal coat is dry ). Users will also need a clean container/cup for mixing, and 100% accuracte measuring tools. Most epoxy products will need a 1:1 mixing ratio of resin and hardener, which means, if you want to make your epoxy food-safe, you will need to use exactly same amount of resin and hardener. If you will pour different amount than recommended, the epoxy will not cure completely.
Mixing both components – Resin and Hardener may take a while. You should mix slowly ( 5-7 minutes ) and carefully or you will introduce air bubbles into the mixture. You will find out that mixing is complete, when the mixture turns from cloudy and opaque to clear. Mix Epoxy very well because if any unmixed resin or hardener remains on the sides of the cup, it will create uncured wet spots. When you will pour the mixture out, do not scrape the sides of the cups to get all of the epoxy out ( there will still be a small bits of unmixed epoxy ). Be sure that the surface you are applying the mixture to is clean, dust free and sanded. It is recommended to wear Nitrile gloves, goggles, respirator when working with epoxy. Epoxy resin mixture is a very sticky and it will be very difficult to remove it if it gets on your skin.

However, there is still a danger of harm if directions and recommendations are not followed carefully. Every Epoxies brand is different and uses different ingredients and ratio in their products.
