Why Mosaic Glass?

Mosaic glass paintings are never static. In the course of the day they are animated by changing light, their patterns wandering across the floor, inviting your thoughts to wander with them. They were essential to the fabric of ancient churches, illuminating the building and the people within, both literally and spiritually. Complex patterns of different colored glasses are used to create a stunning effect.  You can see the way the uneven handmade glass distorts the light, giving a natural organic quality with bubbles trapped forever in the heart of the glass – bubbles that were frozen in as the hot liquid cooled.

Do you love the beauty of mosaic glass? Are you curious how these beautiful pieces of colored glass can be randomly placed on a canvas and somehow develop into an object we recognize? Creating a mosaic glass painting is like creating your own jigsaw puzzle using mosaic glass. If you are a beginner to painting or if you are a very experienced artists, these classes will inspire and amaze you.

Instructions 

  • Draw or transfer your image onto a flat panel canvas or wood. Transfer paper  can make your lines really dark. To lighten your lines paint over your transferred drawing with a thin layer of white paint.  This will ensure your lines don’t show on your finished mosaic. 
  • Pick the glass colors for your subjectI try to use at least 2-3 different shades for each glass color I will use. A sunflower requires yellow glass. I would pick a light yellow glass or a bright yellow glass and a darker yellow type of glass
  • The glass must be washed using rubbing alcohol to remove the dust from the factory or store. Fastest way to do this is by placing the glass in a bowl with alcohol and let it soak a bit. Dry the glass by laying it on a clean towel
  • It’s time to pick the acrylic paint colors and paint your subject. Pick one shade (mid tone) for each colorFor example, a sunflower would require a primary yellow paint or a cadmium yellow paint for the petals. The paint is a background color for each section of your subject. Not every inch of your canvas needs to be covered in glass. The paint will act as a guideline or roadmap for your mosaic glass. For the green leaves, use a mid tone like Martha Stewart Scottish Highlands. For the bud or center of the sunflower use a medium brown like Burnt Sienna with Burnt Umber.  
  •  Paint your subject  on your flat canvas or board before adding any glass. 
  • Use your glass cutters to cut the pieces of glassMake different size cuts, thin, thick, triangular, etc., to make the painting more interesting. I have a video link at the end of this document that shows you a demonstration on cutting the glassBe sure to wear safety goggles or use an old towel to cover your hands when you cut the glassCut various unique pieces of glass first and then plan out where they will be placed
  • Arrange the glass on your canvas. This planning step should be done without glue to get an idea of where you want the glass. Rearrange the glass as needed. It’s easier to work on small sections at a timeWhen you are happy with the arrangement move the glass to the corresponding area on the photo to help remember where it goes. This becomes your roadmap.
  • Place a small dab of Diamond Glaze glue onto your glass piece and place it gently on top of the canvas with the subject you paintedThis is like putting together a puzzle. Refer to your photo to remember where the glass goes.
  • Remember to make each area of the small section you are working unique. Use various shades of glass and various shapes of glass to make the mosaic more interesting. Try using 2 or 3 different color values per area, i.e., dark yellow and light yellow glass, rather than just all dark yellowVariety with the glass color and shape are what gives your work a 3 dimensional effect.
  • Repeat the process for each area of your subject. Cut the glass for just that section prior to adding the glass that area.
  • When you have completed your mosaic you may have to clean some of glass on your paintingUse a small razor to scrap off any paint that landed on the top of the glassUsing a tiny bit of rubbing alcohol, vinegar or Windex on a clean brush works to clean off extra paint.

Instructions

  • Lessons Learned or Mistakes to Avoid 

 

    • Paint - The best type of acrylic paint to use is a thicker or heavy body paint.  The cheap acrylic paint (DecoArt, Delta Ceramcoat, Plaid, Craft Smart, etc. brands) are very thin, making adhesion difficult.  Thicker paint will help the mosaic glass adhere to the canvas better.  I like Liquitex Basics or Martha Stewart paints, they are thicker and better quality paints.
    • Paint the entire canvas first with just acrylic paint.  Let it dry. Use a clear-drying glue like Mod Podge to cover the back of each piece of mosaic glass. Place the glass on the canvas. Do not use modeling paste as your glue since it does not dry clear.
    • It is easier to cut a large amount of glass in various unique shapes  before you begin working on a section.  From these pieces you will “puzzle” out where the glass pieces will go.  Cutting the glass to fit a specific spot is difficult and will really slow you down.  It will be necessary at some point to do this but don’t start off with this precise cutting method.
    • Use tweezers to place some of the smaller glass pieces on the canvas especially in tight spaces. 
    • Separating the glass by color before you begin is a great time saver.
    • 8x10” is a good size canvas to work on. It  takes about 6-8 hours or more to complete.  A smaller size canvas goes quicker but it is more challenging to work smaller.  A 4x4” canvas with a simple subject can be done in about 4 hours.  The time really depends on your experience level and how much glass you use.  Remember sometimes less is more.
