Mosaic Glass Painted Vase Project.

I rather like this mosaic glass painted vase project. It’s based on an idea from the “Complete Guide to Glass Painting”, a book by Alan Gear and Barry Freestone (well worth getting your hands on if you can).

As usual you don’t have to follow our project exactly. We use adhesive lead but you can use liquid outliner if you prefer. (Just ensure it is one which dries hard as you won’t be sealing it down with any paint). We only run the tiles partway down the vase, you can run them to the bottom if you prefer. Our. squares are 3cm but you can change the size depending on the object you are working on and how fiddly or simple you want it to be.

This tile technique can also be used in other projects. I’ve seen it used on both mirrors and picture frames and in both cases it gave a really nice effect.

There are a couple of errors in the video which I thought I’d point out before someone else does! When cutting the tiles I refer to them as 3mm a couple of times when they are obviously 3cm.  I also get my maths wrong and say the vase which is just over 24cm round will need 6 x 3cm square in each row, the real answer of-course (and what I use) is 8 x 3cm squares per row.

(This project works best on both round and rectangular vases which are straight up and down).

Glass Painted Vase Project. Materials and equipment.

  • Thick waterbased glass paints (Homemade or bought).
  • Acetate. (The number of sheets will depend on the size of the vase and how much you intend to cover).
  • PVA Glue.
  • Adesive Lead / Outliners. (As you will see in the video we used adhesive lead, mostly 4.5mm and a single 9mm strip around the bottom. If you don’t have this it can be replaced with a hard drying liquid outliner).
  • Transparent adhesive window film. Optional, colour to suit.
  • Scissors / Guillotine / Ruler. (Depending on how you intend to cut the squares).
  • Boning tool or hard plastic objects (If using adhesive lead).
  • Smoothing tool, Credit card or suchlike. (If using Window fil)
  • Spray bottle for water. (If using window film).
  • Craft Knife.

Glass Painted Vase Project. Technique.

  • Measure up your vase and work out the best size mosaic squares for your project.
  • Make the mosaic tile by “blobbing” the thick waterbased paints onto the acetate.  You can be creative with the colours used  but remember some colours go better together than others. Once the paint is on the acetate spread it out using you finger. I like to do mine side to side but you may like to experiment with swirls etc.
  • Once dry cut into squares.
  • Stick the squares onto the vase using a small amount of clear PVA glue (Elmer’s or school glue for our American friends). Ensure the gap between the tiles isn’t too large. For the adhesive lead it shouldn’t be more tha 4mm, for the liquid lead they will need to be closer. Do one row at a  time to you get a change to more the row around before the glue sets. The second rows gaps should line up with the firsts… etc.etc.
  • Once the mosaic tile have been added then add the window film if you are using it (or a larger piece of painted acetate if you wish).
  • Finally add you adhesive or liquid lead. If you are using adhesive lead please take a little time to work out the order in which you are going to add it. Whenever possible you want to ensure loose ends are covered by another piece of lead.

Variations on the project,

I’ve kept the mosaic pieces “regimented” (i.e. all the same size and in straight lines), I like the look and it is easier when working with adhesive lead. You can if you want cut lots of different sizes pieces and different shapes. You would then build them up on the vase like a normal mosaic, finishing it off with outliner. The finished item would look very different from ours but would give an equally nice effect. You can of-course also use this technique on mirrors, picture frames and other items. With slight adoptions it could also make an interesting project for children!

I hope you have fun trying it out.

Happy Crafting.

Yours, Bob.;
