😂😊Hey u don’t know until u know! I’m sure ur familiar enough with resin that the issue wasn’t the resin itself, it was that u over heated it & that made it begin to kick off too soon. If u warm ur resin too much it causes an exothermal reaction. Next time just warm part A or part B in a warm water bath if ur doing it to compensate for colder temperatures. Maybe save the coffee cup warmer for doing small batch tests on single coasters AFTER u have done ur design, or u know 4 Coffee❤! Some blooms react fine to a heat mat & others will begin to spread/thin out. Maybe grab urself a laser thermometer so u can keep an eye on the temp too! Either way, I respect that u shared the video showing that resin is a fickle bitch & not every project goes as planned as many artists make it seem! If ur learning something from ur mistake, then it’s still a success in my book!
