These vases are made by covering inexpensive glass vases and glass bottles from the recycle bin with anchoring cement. They are surprisingly easy and fun to make.
I happened on the idea of using anchoring cement to cover objects such as the glass vases when I was making my DIY Cement Replacement Sofa Legs for IKEA and Other Brands. When making these legs, I mixed up very thick batches of cement. I noticed that the wet cement could be hand formed for a short period of time because it got thick and pliable, kind of the consistency of silly putty, and then it hardened quickly. It was only in that pliable form for a few minutes. So when I was making the sofa legs, I got in the habit of making little free-form cement bowls from the left-over cement mix. Then I began to think about all the things around the house I could cover with cement, and I decided to try cement-covered glass vases and bottles (before moving on to the furniture 😀 ).
