This modern concrete fireplace doubles as a coffee table on wheels. I used Quikrete 5000 cement mix poured into a melamine mold to make the table and added charcoal pigment from Quikrete to give the concrete a dark grey color. The manufacturer of the fireplace insert claims that bio-ethanol fuel is safe indoors and out, but I would only use the table outdoors. I was curious about ethanol fireplaces so I bought one from Moda Flame (not a sponsor) and made a simple, concrete table on wheels out of Quikrete 5000 that has an opening to accommodate an ethanol fireplace burner. This isn’t a cheap project. I purchased the 3-liter indoor/outdoor burner for $99.99, but believe the price has increased since then. I got four 8” heavy-duty steel casters from Amazon for about $110.
