Welcome Kitkat, hope you enjoy it here in the forum...
I don't see why it would be a problem, depending on how big the bits were...

Hi KitKat.
It shouldn't be a problem as long as you use the correct adhesive (basically you want a cement based product rated for external use). Also, if you cut the pieces small, then the curves shouldn't be a problem. If you get cold enough to get frost where you are, then the ceramic must be frostproof, otherwise moisture will get in and crack the tiles and pop the glaze off. Sorry if I'm stating the obvious here.
There is an excellent book called Making Concrete Garden Ornaments (or very similar) by Sherry Warner Hunter on working with concrete, which also covers some specific mosaic issues. I'm pretty sure she has a web site if you google her.

| I have a huge resource of small offcuts of the most beautiful glass in the world. It's too good to throw away but......how do you use it? Mosaics would seem to be the answer but....it would be a lifetime's work for one person [to use it all] and how do you stop sharp edges being a threat in the finished work? Would the indirect method solve this? There is such an overwhelming quantity it is not, repeat not, viable to grind the edge of every piece. |

If the glass is all of the same thickness and it's going on to a flat surface, grouting should take care of the sharp edges. If there is something lethal like a very sharp triangle point, I'd probably just grind that down a little, but not otherwise.
The indirect method won't solve anything about the edges. That's a method for achieving a flat surface with materials of different thicknesses. If you have any spare though, I'd be up for some  |

Thanks Marian. It's 10 years worth of offcuts from a stained glass business. The glass is ostensibly 3mm but it varies a lot btween mouth blown antique to heavily textured American.
I thought the indirect method would cause the mortar to reach the same level as the top of the glass, thereby covering the edges.
I have my own experiments going with laminating [coloured on clear] so I can use the same transmitted light as a leadlight, but I'd need another lifetime to use it up that way! |

Traditionally, you pre-grout from the back with indirect, which stops the mortar squishing through. The grout will protect the edges though - it should be flush with the top of the mosaic. What the indirect method will give you though is a level face to the piece, even with glass of different thicknesses. To do this, you need to butter the back with your cementitious adhesive before setting the mosaic on the substrate. If you do pre-grout, you need to make sure the backs of the tesserae are clean of any excess grout before setting the mosaic. |

Thanks Marian, 'cementitious' i'll have to remember that one.
Did I see somewhere that you have a shop? In Arnecliff? Would love to drop by if that's the case. |

No worries.
No, no shop. In fact there are no longer any dedicated mosaic supply shops in Sydney, just on line suppliers and Finns has some stuff I think, but mainly stained glass.
I work from a home studio in Bayview, but if you want to visit that would be fine. email me. mshapiro@dariandesign.com.au |
