How Engineered Quartz Countertops Are Made

April 7, 2017 11:50 am Published by

Engineered quartz countertops are gorgeous and come in a nearly infinite array of patterns and colors to perfectly suit your design needs. But while they have many of the exact same properties of non-manmade stone, such as marble or granite, they are often much more competitively priced and more flexible to your needs.

The engineered nature of quartz greatly reduces costs compared to mining slabs of whole stone out of a quarry. Other advantages include a perfect seal — no polishing or having to seal every six months! You can also dictate the exact color and shape you want without incurring hefty premiums.

How is this possible? Fabricating quartz surfaces involves a much more flexible process than materials that are purely mined. Learn how this happens and how you end up with great-looking, durable and versatile surfaces at a relatively low cost by reading about the engineered quartz manufacturing process below.

Making a Stone Surface from Pebbles

Like marble and granite, engineered quartz counters start their life in a quarry. The prime difference is that quartz does not have to be mined out in solid slabs. Instead, the quartz can be immediately crushed and turned into a pile of angular rocks known as an “aggregate.” This aggregate can even be made from byproducts of other mining operations, including granite.

Aggregate mixes are filtered and sorted according to similar qualities, allowing you to have control over the appearance and luminosity of your quartz countertop base material.

When it comes time to turn all this crushed rock into a counter, a chosen mixture is dumped into a vat with resins, binders and dyes. A completed quartz counter is usually 90 percent to 95 percent pure quartz.

The mixture is made in a certain way to create pre-established colors and patterns. For instance, some counter mixes will be one pure color, whereas others will inject dye to create swirls or faux-marble appearances. When the mix is optimal, it is placed on an extruder to harden into a solid slab shape.

From Quartz Slab to Finished Product

When you have selected a final design for your quartz counter, including a color, pattern, edge finish, and custom shape, your counter materials will then be cut from the pure slabs. Testing ensures that you get the most pure, dense section of any given slab. As this video shows, the slab is then cut with a saw or water jet. To obtain the exact finishing specifications, a miter or CNC machine will make the cuts to provide the angle and bevel desired.

The counter pieces are then assembled and seamed to create the appearance of one uniform slab with no visible joints. Typically, workers will then hand-polish and finish the edges before testing the product to ensure it meets your expectations.
