Northern FeldsparNorthern Feldspar Quarry Near Sudbury, ON

Our Northern Pink Feldspar has very unusual characteristics and this comes from the manner in which it was formed. Millions of years ago, a mass of magma (molten rock) intruded the country rock and cooled quite slowly thereby allowing very large feldspar crystals to form. When you hold a piece of Northern Pink Feldspar in your hand you are holding a fragment of a crystal originally up to many inches in length. All of this translates into beautiful and highly reflective aggregate with an interesting texture and a rustic orange glow.

Range of Sizes: 1 1/2" Landscape Stone, 1/2" x 1/4" Concrete Stone, 3/8" x 1/8" Clear, 1/4" x 1/8" Clear, -1/4" Screenings

Madoc White MarbleMadoc White Marble Quarry Near Madoc, ON

Madoc White Marble is the white terrazzo stone staple in Canada to the point of it being difficult to find a terrazzo floor with white stone that is not from Madoc.

But production at this quarry is a not without challenges - white stone being what it is makes the presence of off-colour particles very noticeable. And given that this quarry has been producing terrazzo stone since the 1950’s Upper Canada has had to utilize some innovative quarrying techniques.  It continues to be our priority to deliver a white, consistent product for many years to come.

Range of Sizes: Standard Terrazzo sizes. Custom clear stone and sand sizes are available, please enquire.
