Mosaic Coffee Table Pre-Grouting

Changing Grout Color With Paint

The following method is only recommended for dry indoor mosaics. Artist Megan Adams recently used it to save a mosaic that had been compromised by white grout, which makes tile colors look less intense and the mosaic as a whole “bleached out” in appearance.

We put white grout in bathrooms because it is used as an indicator of cleanliness. It’s use in mosaic art is limited to making your project look like a summer camp project. Avoid it. Consider black or dark gray grout instead to make your colors look intense.

Also keep in mind that traditional sanded grout is lighter in color when it hardens, and so sometimes a light gray or light brown grout can turn out looking like an off-white and cause the same problem as if you had used white grout.

How To Use Iridescent Tile For Lights and Reflections

If we gave an award for best use of iridescent tile to create a sense of lighting in a scene, artist Terry Broderick’s mosaic “Pittsburgh Cityscape,” would have won it hands down. It is a must-see mosaic.

Even if you aren’t planning on using iridescent tile for lights in a night scene, Terry’s mosaic is worth taking a look because the sense of light and atmosphere he creates in it is nothing less than impressive.

If you are trying to make things like stars in a night sky or streetlights reflecting across water, this mosaic is a tutorial on how to do it right.

Chakra Tree of Life Mosaic, A Study in Design

Artist Betty Ackerman recently used our fire-polished millefiori (the Mud-Turtle Mosaic brand) and stained glass to make a circular mosaic in the form of a rainbow-colored tree of life with a column of chakras spiraling inward on the trunk. Betty calls her mosaic “Chakra Tree of Life.” The first mosaics I ever made were found-object “mandalas” in the form of a tree of life in an oval, and so Betty’s design spoke to me.

I wanted to share this mosaic because Betty did a good job at maintaining adequate contrast between the tree and the background and between the branches and the leaves in spite of the color transition in the design. It would have been all too easy for the figurative element of the tree to become lost with this much “visual interest” going on in every square inch, and so the mosaic is worth studying.

Glass-on-Glass Mosaic Table

Artist Melanie Squires recently completed a stained-glass mosaic table, and I wanted to show it off for several reasons, and not just because it looks so good. There are some materials and methods to discuss, and there is the use of impressionism for the koi, which I thought was particularly effective.

The Table

Melanie made the table from a metal patio table with a glass top and attached the stained glass to it using silicone adhesive.

Warning: If you use a glass patio table for a mosaic, make sure the glass is thick enough to support the weight of the mosaic. It is possible to find glass patio tables at thrift shops where the original thick glass has broken and been replaced with something thinner. It is also possible to come across cheaply-made tables with thin glass, especially end tables and coffee tables.

Never use a table for an outdoor mosaic merely because that is the table you happen to have. Before you invest time, money, and materials, make sure it will last.

Cleaning Grout from Pits in Vitreous Glass Tile

Vitreous glass tile has a lot fewer surface pits than it did a few decades ago, but it still has some, at least in most brands. Grout can sometimes lodge in these superficial pits if you don’t adequately sponge and haze the mosaic after grouting, and many novices find this problem particularly distressing.

The good news is that the problem can be fixed easily, and it can be avoided for the most part by correctly sponging and hazing the mosaic during the grouting process.

Avoiding The Problem

You do NOT need to find vitreous without pits to avoid the problem of pit staining.

Keep in mind that the same vitreous tile is used as an architectural covering for thousands of square feet at a time, and so common sense tells you that there has to be a way to get grout out of pits without a large amount of labor.

I feel the need to stress that point because I receive emails from beginning mosaic artists who are desperately searching for vitreous glass tile that is perfectly smooth without the occasional pit: You do NOT need to find perfectly smooth tile.
