The Process behind Making ProTerra Apron-front Kitchen Sinks

Évier en argile réfractaire ProTerra M125

An apron-front sink, also know as a farmhouse sink, is a sink that has an exposed front-facing side once installed. Very trendy in a Scandinavian or modern kitchens, this type of sink is offered by Prochef in stainless steel finish for a modern look or in a fireclay finish for a classic look.

The fireclay apron sinks in the ProTerra collection are designed in Quebec and manufactured in Italy with the highest quality materials. Prochef sinks go through a rigorous quality control process to ensure dimensional quality and an impeccably smooth finish.

Fabrication Évier ProTerra Argile Réfractaire

Here are the four steps in the production of a ProTerra sinks:

1. Mixing the minerals

ProTerra sinks are made from minerals extracted from different regions of Europe. They are mixed together to create the slip that is then used to mold the sink.

2. Shaping the sink

Once the slip is in the mold, it takes several hours of drying in a controlled environment for the sink to be properly shaped. This process requires a great deal of skill as the sink must be perfect. The mold is then removed to reveal the result: a fully functional kitchen sink.

3. Quality control and finishing

Quality control tests are performed to detect any defects. Each sink is inspected before the final touch is added: a layer of enamel that will give the sink it its beautiful glossy white finish once fired at high temperature.

4. Kiln firing

This last step allows the sink to have its exceptional look and quality. The sinks are fired in the kiln for 24 hours at temperatures that reach up to 1200 °C. The firing allows the clay and the enamel to fuse together and thus ensure increased resistance to scratches and various impacts that can occur in the kitchen once in use. It is also the firing of the enamel that gives it the glossy, non-porous finish that makes ProTerra sinks so easy to clean.

These four steps create unique and high quality products. Each fireclay piece is handcrafted, which gives it a handmade touch and explains the ±3/16" variation from one sink to another. We recommend that you always have the product in hand before cutting a countertop.

ProTerra collection sink models

Prochef offers two models of kitchen sinks in the ProTerra collection: the M40 and the M125. The ProTerra M40 collection offers a reversible apron: one side with a flat apron and one side with a Shaker-style apron. The 3/4" rim offers a sleek but durable look. As for the ProTerra M125, it has a flat apron on all four sides. The sink walls are thicker for a more traditional look.

Both models are high-quality products that are installed the same way. A country sink can be installed in a number of ways, but the two most popular types of installations are undermount and exposed rim. The installation guide provides details on each.

Installing an undermount apron sink

Just like for stainless steel sinks, the undermount installation of a fireclay apron sink offers a clean, uncluttered look. The sink is installed on a solid base for heavier fireclay sinks and then the stone countertop is placed over the edges of the sink. This type of installation makes countertops easy to clean since dirt can be swept directly into the sink and provide larger countertop surface.

Installing an apron sink with an exposed rim

The fireclay apron sink can also be installed with an exposed rim. In fact, for a more country look, it is possible to install an apron sink slightly higher than the countertop. This highlights the sink and prevents objects from falling into it.

Maintenance of a fireclay sink

To keep your sink in great condition for many years, it is essential to apply proper care. It is recommended to clean it daily with a sponge or cloth and a non-abrasive cleaner or mild dish soap. Rinse with warm water and dry with a clean, dry cloth. This will maintain the glossy, white finish.

If a stubborn stain appears, gently scrub it with a cream cleanser and rinse with clear water. Dry it off and the stain should be gone!

Also, to avoid damaging the bottom of the sink with sharp utensils or dishes, we recommend using a grid to protect the bottom of your sink. Save time with Prochef's dishwasher-safe sink bottom grids! The use of a rubber mat is not recommended as food, water and soap can accumulate and stain the sink surface.
