A couple of notes before beginning:
You will need to work quickly with Total Cast if you mix all the colors for the Tetris blocks at once. If you prefer, you can mix several smaller batches of resin so that they don’t set up on you before you pour them into the trivet.
The coaster mold used in this project has a 3 ounce capacity but yours may hold more or less resin, so adjust the quantities of resin to suit. A search online will bring up many options for you to choose from. If using a plastic mold, then apply a good mold release before pouring in the resin.
Measure 2 ounces Resin and 2 ounces Hardener. Mix the two parts together thoroughly, scraping the sides and bottom of the cup during mixing to make sure that all the resin is mixed.
Divide the resin equally into 6 small cups. Squeeze a few drops of pigment into each cup and mix the color thoroughly into the resin.
Pour each color in a block shape on the trivet.
Air pockets tend to form in the corners of each cavity so if you have time before the resin begins to gel, use a toothpick to poke the resin into the corners. This will give you square corners on each pixel.
Pass the flame of a gas lighter over the surface of the resin to pop any bubbles as they rise to the surface. Set the resin aside to cure overnight.
Always use caution when using a flame to avoid injury or mishaps.
Once cured, pop the pixel blocks out of the mold by peeling the trivet away from the resin.
Cut the blocks into Tetris shapes. You will need to use a utility knife to get into the awkward corners where the scissors can’t maneuver.
Mix a 1 ounce batch of resin and color it with the black pigment. Pour it into the bottom of the coaster mold. Pop any bubbles by passing the flame across the surface, then set the mold aside until the surface has a firm “skin”. This will take several hours.
Work out how many pixels can fit along the bottom of your mold and then arrange the block shapes so that the pieces interlock for about 4 to 6 rows.
Place the blocks back into the trivet, face down, in the pattern you’ve just formed. Place a piece of tape across the back to secure them all into position. Remove from the mold and trim the excess tape away.
Once, the black resin has formed a firm skin, align the long edge of the taped pixels at the bottom of the mold and carefully place it onto the resin, tape-side down, making sure that there is an even border all around it.
Place another couple of Tetris blocks in the blank space above the main blocks as if they are moving down the screen. Set the mold aside for the black resin to cure.
Mix about 1-1/2oz of resin and pour it over the blocks.
Use a tooth pick or needle tool to work it down into the space between each block. Tease out any air pockets that have formed in between the pixels. Pop any bubbles. Leave until it forms a firm skin.
Demold the coaster.
Mix a 1/2oz of resin and create a domed layer to finish the coaster.
The finished product is retro and fun! What do you think of this tetris coaster DIY?
