Under Glass

Follow these steps to découpage under a glass plate. You can use the same process for the inside of a vase or a glass.
Materials: glass plate, cut out picture, Liquitex Gloss Medium & Varnish, PVA glue, sponges, water, gold/silver leaf, gold size, cotton gloves, cotton bob.
  • Seal both sides of your picture at least twice with Liquitex Gloss Medium & Varnish LGM&V)
  • Place the picture down, face up, on a towel. Place the plate over it and move the plate until you are satisfied with the position of the picture.
  • Use a grease pencil to trace the outline of the picture on the top surface of the plate
  • Put the pictures aside and turn the plate over to the back side.
  • Spread PVA glue on the plate where the picture will be.
  • Position the picture face down on the PVA glue
  • Looking from the right side, position the picture under the traced outline in the correct position.
  • Put some more PVA on the back side of the picture and gently massage with your fingers from the centre outward to remove any air bubbles.
  • Wipe up the excess glue with a damp sponge.
  • Make sure you leave glue under the picture so it will stick.
  • Work on the air bubbles to push them over to the edges of the picture.
  • You will need to work on your picture for quite some time as new bubbles appear.
  • When you think you've got them all, and you can feel the picture "grabbing" to the plate,stop touching the picture and rest the place face down on the towel.
  • Before the glue hardens use a damp sponge to wipe off the excess glue, being careful not to dislodge the picture.
  • Let dry overnight.
  • The next day check for air bubbles and edges that are not stuck down properly. Attend to these and let dry.

BACKGROUND 1 PAINT

  • Now you are ready to start the background. If you are going to paint a background, do it now. Sponge on a mixture of colours that are complimentary to your picture.
  • When the background is dry, mix some gesso and paint and apply this to the back of the plate. The objective is to get a smooth finish on the back of the plate.
  • Lightly sand the gesso/paint when it is dry.
  • Apply another coat and sand again. Keep doing this until you are satisfied that the back is very smooth.
  • Seal with LGM&V
  • Apply two coats of your favourite varnish.

BACKGROUND 2 METAL LEAF

  • If you are going to use metal leaf, apply a coat of Langridge's Gold Size over the whole of the back of the plate, over the edges of the picture and the glass.
  • Let it get tacky. Test with your knuckle.
  • Put on your cotton gloves
  • Lay the metal leaf (whether gold or silver) down over the size, overlapping the sheets slightly.
  • Press down firmly on the leaf with your bob.
  • Leave the leaf to settle.
  • Use a soft brush to brush off the excess pieces of leaf (skewings) and save these in a screw-top jar
  • Hold the plate up by the edges and view it from the front and see if there are any bits of light showing through the leaf.
  • If so, apply a bit more size and a piece of leaf to cover.
  • Continue to do this until you have all the holes covered with leaf.
  • Let stand overnight.
  • Seal with white shellac.
  • Seal with LGM&V.
  • Proceed with the gesso/paint method described above.

BACKGROUND 3 OXIDISED LEAF

  • Follow the process described above until you have the gold or silver leaf applied..
  • Now sprinkle salt all over the back of your plate over the metal leaf. This can be ordinary table salt.
  • Scrunch up some tissues and soak them with vinegar.
  • Place them on top of the metal leaf close together.
  • Be sure to use lots of salt and lost of vinegar.
  • Leave them for several hours and then check by lifting one off the plate..
  • You are looking for holes that have been eaten into the metal leaf by the salt/vinegar process..
  • When you are satisfied that the holes are large enough and you like the look, take the tissues off.
  • Brush off the salt.
  • Seal with shellac or LGM & V.
  • Now sponge some transparent paint on to the plate. (Check the paint tube to see if it is opaque or transparent.
  • Allow to dry.
  • Finish with paint and gesso as described above.
  • Seal with shellac or LGM & V.
