This is the first time that I have poured into Silicone Molds. I used Quikrete quick setting concrete. Thankfully my Little Brother has poured hundreds of rocks and had already worked out the kinks for me. I used 13.2oz cement to 5oz water for my largest mold (5.5" diameter). This concrete hardens quickly. This small batch pouring worked perfect for me, giving me plenty of time to mix, pour and tap out bubbles before it hardens. I use the same mixture measurements for all my molds and just keep mixing and pouring until all molds are filled.

Once I get more comfortable pouring, I will make a real-time video covering the whole process =)
