Review on 🔵 High-Quality Silicone Mold Making Kit - 2.2 lb Sapphire Blue Silicone Rubber for Casting Resin & Silicone Molds by Amy Wilkins

I have been making molds for a long time and I always buy the familiar silicone without any problems. Thought I'd give it a try as it's a lot cheaper. Very disappointed, I measured it carefully, stirred it for at least four minutes, and attempted to make a two-part mold. The top not surrounded by the mold box looked fine after 12 hours, poured the second part with a good quality silicone mold release which I have used many times and tried to remove the mold after another 12 hours. The areas surrounded by the molding box are a sticky mess that didn't set properly and the halves wouldn't separate. If I didn't use both sets they would come back, never again. The temperature was a controlled 73F so it didn't matter.
