About Fireclay Kitchen Sinks

As the name implies, these are sinks made from clay that have been fired at high temperatures to harden them and glazed to make them bright, beautiful and resistant to stains, germs and scratches. Fireclay sinks have been manufactured in England for well over a century, and some of those early sinks are still in use today.

The process begins with the mining of fireclay (or fire clay), an argillaceous clay with very high heat resistance. The material is used as fire brick and to line furnaces. It is also made into metalworking crucibles, glassware and pottery.

Fireclay is combined with water to produce a mixture known as “slip.” The slip is poured into molds made of material that absorbs water to facilitate the drying of the clay. The work, known as slip casting, is done largely by hand. When partially dried, the sinks are removed from their molds, and any slight imperfections are worked by hand to create a smooth, consistent surface before the final drying process. If there are significant imperfections, a rare occurrence, the sink is scrapped.

Finally, several coats of glaze sprayed onto the sinks, and they are fired in kilns with internal temperatures above 2,900 degrees Fahrenheit (vs. about 2,200 F for cast iron). The glaze fuses with the fire clay to create a non-porous finish that isn’t damaged by acid, won’t harbor bacteria and resists scratches.

The traditional fireclay sink is a farmhouse sink, also known as a country sink, Belfast sink or Butler sink. However, the sinks made from this material today offer many more options.

Is a Fireclay Sink Right for Your Kitchen?

Fireclay is used in some of the very finest farmhouse sinks, and if a farmhouse/apron sink fits your design, and fireclay is in the budget, you’ll probably be very pleased with your sink.

If your design is more contemporary, there are fireclay sinks to fit the design too. In short, if you’re willing to pay more for a high-quality, very durable sink, fireclay is certainly a premium choice.

Installing a Fireclay Sink

This material is very heavy, so you’ll need additional support for the sink. The most secure way to provide it is with vertical supports that extend to the floor. Some sinks also require mounting to the wall.

Talk with the seller or the installer about the best means of supporting the weight. The key is to take weight off the countertop so that it doesn’t bow. Bowing can crack stone or tile and lead to gaps between the sink and countertop where water can infiltrate. Even a bow of 1/16” can produce a leak.

Fireclay Kitchen Sink FAQ

This fireclay kitchen sink Q&A covers other topics which might be of interest to you.

A lot is made of the high firing temperature for fireclay. What is the significance of it?

The super-heated kiln produces a very durable fusion between the glaze and the clay. This means it is less likely to chip. It also produces a glass-like finish that is non-porous and very easy to keep clean and sanitary.

I thought clay is cheap. Why are fireclay sinks so expensive?

There are several reasons for the higher price:

  • Fire clay isn’t as common as some types of clay, so it costs more
  • The glaze is of the highest quality
  • Making a fireclay sink is time intensive from mixing the slip to drying the sinks to firing them
  • The primary factor in the price is that fireclay sinks are handcrafted by skilled artisans who spend many hours on each sink

Some fireclay farmhouse sinks are reversible. What does this mean, and why is it important?

A reversible sink has a traditional farmhouse face on one side and a more contemporary face on the other, so you have a choice of which look you prefer for your kitchen scheme. The drains in these sinks are always in the middle.

What are the differences in fireclay and porcelain-enameled cast iron?

A fireclay finish is harder than porcelain, and rust spots won’t develop if it is chipped, as is the potential with cast iron. A cast iron sink can be reglazed, tough at significant cost. Otherwise, the way they perform and their strengths and weaknesses are quite similar.
