This quote is taken from an article in an Australian tiling magazine ( http://www.infotile.com.au/pdfFile/advicetopic/48201031834.pdf) and concerns a court case from a few years back. This quote below is the Britsh Standard comcerning how much area on the back of a mosaic glued to mesh should be kept free to allow the adhesive to bond with the tesserae. At the bottom of the page I have a suggestion on how to ensure your glue doesn't cover all the tiles.

I've just put up a new article on getting the right technical information. There's a whole myriad of different adhesives, grouts, baseboard etc out there and knowing the right ones to get is more about asking yourself the right questions before going into the store than about the questions you ask the people there. |

Until I can get the video done, which will most probably be after Christmas now then here is a photo series on sharpening the hammer and hardie using and electric grinder. |

I now have a tumbing machine! I've been after one for a while so now all the cut tiles will go through the tumbler to round of the edges. I'll also be trying out the various polishing grits out there to see how these work on the marble surfaces. |

 I always like to try new things and this is trying out an adhesive on mesh. This is a 20cm ish piece of mosaic and the tesserae have been glued on using Bostik, Sticks Like S**T adhesive. I left it for over 24 hours then to see how well it stuck I threw it across the yard a few times, up into the air and let it drop then rolled it up and threw it hard into the wall from 6 feet away. The result is... it only had 4 tesserae come away. I can use this for the portable mosaics I take around to the museum demos I give but I do need to sort out a few things before I'm totally happy but it's a good result so far. |

If you've ever wondered how many tesserae (cut stone tiles) there are in a Roman mosaic (go on admit it, it keeps you up at night)then here's how to work it out.
The average size of tesserae used in a Roman mosaic was 8mm - 12mm
1 kg = 400 tesserae (approx)
26 kgs needed for 1 m2 (approx 3')of mosaic
So a room of 6m x 8m dimensions the mosaic for that floor works out as:
6m x 8m = 48 m
48 m2 x 26 (kgs per m2)= 1,248 kgs
1,248 kgs x 400 (tesserae per kg) = 499,200
These are approximate figures, some tesserae were larger some smaller but 8mm - 12mm was the average. If you go smaller it tends to be 5mm x 5mm x 5mm in which case you just times the m2 number by 13 kgs instead of 26 kgs. |
