In this week’s experiment, I mixed one ounce of Castin’ Craft Easy Cast resin in a 10 ounce reusable plastic mixing cup. I separated the resin into individual 1 ounce mixing cups and mixed in 1 to 2 drops of each of the Resin Obsession transparent color pigments.
Note: On this purple batch, I unintentionally mixed in more than that. I mention it because it mildly impacted the final casting as I will tell you about in a bit.
Not shown: Both molds were prepped with a light mist of Castin’ Craft mold release and conditioner 30 minutes before pouring the resin.
The results after they were demolded: SUCCESS
The colors in the Easy Cast were what I would expect using them in the Resin Obsession super clear resin.
So what was my little blunder? When I squeezed transparent purple color into the resin, I added in 4 to 5 drops instead of the 1 to 2 drops as in other colors. While the resin cured, it cured with the back of the casting tacky. It did this because the Resin Obsession color pigments contain epoxy resin. That resin requires extra hardener to ensure it cures properly. Adding that much color to that small (3 to 4 cc of mixed resin) was enough to cause that problem. The other colors cured normally. To fix it, I would dome a little bit of mixed Easycast resin to the back of the resin charm and allow it to cure.
