Brickyard Scientist (brick mold)

thingiverse

This mold is specifically designed for crafting bricks with precision. You'll need Type 1 silicone to fill the space effectively, using almost an entire tube to create quick-setting silicone from caulk. Watch this video: https://youtu.be/0jFjaVuueEU, and note that only a minimal amount of soap is required, approximately 2 tablespoons per gallon. Insert the ball of caulk into the mold by starting at one side and working your way outwards to release any air bubbles that may become trapped. To create the bricks, use fast-setting cement that doesn't contain large rocks. Always check the bag for a guarantee that it can be shaped into a feather edge. I personally use Cement-All, but since it's white, I add some grey charcoal coloring to achieve the desired color. Making multiple silicone molds allows you to produce up to 200 bricks at a time with ease and efficiency.
