Steampunk Mosaic Coasters

7 Materials
1 Hour
We love to make mosaics and we especially love making them with resin. The clear resin lets the mosaic design really shine through. If you've never tried resin before, have no fear. It's all about mixing the two parts of the resin. And we'll show you how!
For this project we wanted to make coasters, but we couldn't find bases we liked that had sides to hold in the resin. Then we thought of jar lids. Cheap and the perfect size! We spray painted ours silver inside and out.
Next we made our mosaic design with glass tiles and little metal gears and things. We just glued them into the jar lids with permanent glue (you could use clear silicone). We made each coaster a little different from the next.
For resin we used Envirotex Lite Pour-On Finish. To mix your resin, pour 3 ounces of hardener in one cup and 3 ounces of resin in another. Then pour the two parts together into a third cup. Stir thoroughly for two minutes, then pour the contents into a fourth cup and stir for another two minutes. Pour the resin over the mosaic.

To watch our video showing how to mix the resin, click here.
About ten minutes after pouring the resin, little bubbles will appear. Exhale over the surface of the coaster to release the bubbles. (The carbon dioxide in your exhaled breath releases the bubbles.) Let the coasters cure in a dust-free area on a level surface for 48 hours.

We love how these Steampunk Coasters turned out. Hope you'll try making your own!

Remember, if you have any questions while you're working on your mosaic coasters, just leave us a comment and we'll reply! We really love hearing from you.

    Anything cheaper to use instead of resin?

    Who told you the carbon dioxide is what made the bubbles come up and pop?

    Exhaling over it doesn’t make the bubbles go away because of the carbon dioxide it’s because of the warm air. If you use a small soldering torch it will do it quicker and without getting dizzy

    Love it! Is there a way to do the same but remove them from the lids (using the lids just as a form for the coaster?

    I love this Idea. I have never worked with this medium before. I was always afraid it was just one of those that would be too difficult and I would find myself frustrated and angry. But you made it sound so easy. I feel like I will have to give it a try after we get my craft room finished. Plus we inherited my in-laws home. My father-in-law saved everything you can imagine. From anything metal to books on heating and cooling systems starting from the late 50’s to medicine bottles which were collected in the large Folgers coffee cans. This has definitely given me some great inspiration and ideas.

    Very cute! I'd glue a piece of cork on the bottom, just so the metal doesn't scratch anything or the paint come off.
