Mosaic Mirror Oxidation Detail

Mirror Mosaic Warning

Silver-backed mirror must be glued down using a special mirror adhesive; otherwise the reflective silver will oxidize and turn black. Mirror tile is a different situation.

Mirror Vs Mirror Tile

Note that this warning is about pieces of broken mirror being used as tile. Mirror tiles such as the colored glass mirror tile we sell have a special epoxy coating over the silver to protect it from adhesives. In that case, you can use Weldbond and do not have to worry. Continue reading

Creating Motion Using Curved Andamento

Artists can create a sense of motion in their mosaics by using concentric curved rows of tile, especially in the background around figures.

To me this use of andamento* is one of the most interesting aspects of mosaic, and it is an easy way for novices to make art that really engages the eye. I used this technique in the first mosaic I ever made, and when I used a photo of that mosaic to make our logo, I blacked out the figure of the fire bird to emphasize how much of the sense of motion was creation was created by the andamento in the background.

*The Joy of Shards mosaic website defines andamento as the visual flow and direction within a mosaic produced by the placement of rows of tesserae (pieces of tile).

Staining Grout with Acrylic Paint

Staining Grout With Acrylic Paint

Mosaicists sometimes mix in artist acrylic paint to create custom colors from white grout, but you can also use acrylic paint to “stain” grout after it has hardened (for dry indoor mosaics).

Like the process of staining wood, “staining” grout with paint is a process of wiping on and wiping off. The paint sticks to the rough grout but wipes off the glass tile. Continue reading

Consistent Grout Gaps

In my recent blog article about black and white grout, I wrote the following tip for minimizing the width of grout gaps and working a little faster at the same time:

If tiles only touch at points but not along the length of their sides, then tiles can be positioned very closely and yet still be grouted. Consider working in this way instead of carefully cutting each tile to maintain a uniform grout gap.

I need to clarify what I meant by that.

Uniform Versus Consistent

Sometimes novice mosaicists will carefully cut each tile to maintain a perfectly uniform gap, which can be a little tedious, and worse yet, they make the gap a little wider than it should be because the artist does not have the experience to visualize what it will look like when grouted.

I think it is better to work a little less uniform, and to err on the side of being slightly narrow, even if that means tiles occasionally touch at a point or corner. By better, I mean more efficient, less tedious, and better looking.

All that being said, it is extremely important that the mosaic have the same type of grout gap in all regions. You want to be consistent in your style of gap. You do not want to have loosely executed in one place and tightly uniform in another, nor do you want wide gaps in one region and narrow gaps in another. Continue reading

Increase Visual Interest by Using Variegated Colors

You can increase visual interest in your mosaic by using variegated colors (multiple colors in patches or streaks) instead of monochromatic fields of only one color. This technique is particularly effective if your design is relatively simple and made from outlined areas of color like a coloring book or cartoon. Continue reading
