Tiles and Mosaics for Potters

Description

If you are a potter you already know much of what is needed to manufacture tile. However there are some things you need to unlearn to make tile well.

Article

Ceramic supply companies are often amazed at how well some of their tile-making customers are doing and how quickly their businesses sometimes grow. You may not be aware of how quickly the hand-decorated tile, custom tile, and mosaic tile businesses have grown in the past few years. For example, visit http://axner.com and search the 'books' area for the word "Tile", some stunning books are available.

Anyone who has visited a modern tile plant in Italy, Spain, Turkey, etc. is amazed at the innovation of these companies and the kind and size of automated production equipment they use. The dust pressing, silk screening, glass fritting, engobing, fast firing processes that are the mainstay of the industry are almost completely unknown to potters. However, although these companies produce huge volumes of tile, there are many niche custom tile markets for small players to fill around the world.

There are some interesting aspects of tile production that make it a good 'bread and butter' source of income compared to more traditional forms of hobby pottery. For example:

However if you want to make your own tiles you should be aware that you will have to relearn and unlearn some things. Techniques that you may have gotten away with in pottery will not necessarily work in tile production. For example, avoiding drying cracks and dry warping can be very difficult in hand made tiles made by a pressing, rolling or extruding. This is because the clay body must be plastic and have a high water content (and therefore high shrinkage).

By contrast, industry employs dust pressing, it is undoubtedly the fastest and most precise method for tile making and no drying racks or chambers are required (RAM pressing is also used for special shapes). Dust pressed tiles have no drying shrinkage and remaining water can be expelled in the kiln. Also, the dust pressing method puts a lot of the burden of manufacture on mechanical engineers (which are easier to find than ceramic engineers).

Potters who begin making tile also find it very difficult to fire tile without warping it, even at low temperatures. Industrial kilns, by contrast, can heat a tile so evenly that vitreous tiles up to 120cm by 80cm can be fired perfectly flat and very quickly. Standard tiles, even vitreous ones, can be fired in an hour. The average potter would say that these things are impossible (they are in any kiln they are used to using). Industrial kilns are highly controlled tunnels that the tiles convey through in a continuous fashion, periodic pottery kilns require a lot of shelves to fire any amount, this severely reduces kiln efficiency an evenness of firing.

The tile industry is very well represented on the internet, perhaps better than any other segment of ceramics. Check out a search engine for some inspiration. There are some amazing tile shows held around the world, the one in Orlando, Florida each year, for example, is huge. While it is mainly tile companies show casing their ware at this show, there are lots of related industries that participate also. Anyone interested in tile who walking through a show like this will have ideas flooding into their minds faster than they can write them down.

If you are serious about tile production, be willing to get your information from industry rather than other potters, that is where the real knowledge can be found. If you can find a way to communicate with the ceramic engineers at these companies (not the salesman) you will often find them very helpful and giving, that has been our experience.

Here are a few suggestions if you are beginning to make handmade tiles:
