Can you mix dark and light glass?
A dark brown glass in a dark brown matrix can have an appeal all its own. Mixing light and dark colors of glass will give you a terrazzo effect. If you use clear glass aggregate, it will take on the color of the matrix, and it will add the most depth. Since glass is acid resistant, acid staining will color the surrounding matrix without affecting the color of the aggregate.
Can you make a cullet out of empty beer bottles?
And then there’s always your personal stash of empty beer bottles. With a small investment in a high-impact glass-crushing machine, you can make your own cullet, though some contractors opt to do it the hard way — with the help of a scrub brush to remove labels, safety goggles to protect eyes, and a hammer to do the dirty work. The use of a good crushing machine is preferred, though, because it doesn’t produce the sharp, dangerous edges of the hammer-the-bottle method.
What Will Concrete Stick To?
Concrete can stick to some forms of wood. But the bond isn’t that strong. With a little force the wood will detach from the concrete.
Does Concrete Stick To Aluminum Foil?
Don’t use concrete with aluminum foil or other aluminum products. The chemicals used to create cement react with aluminum and start to break down. Every time I’ve tried using aluminum foil with concrete, the foil has deteriorated and been eaten away. It’s a very bad mold liner. If you’re looking for something to line your mold with try wax paper or a release spray.

What is colored glass aggregate used for?
Dave Blasdel, owner of Blazes Concrete Impressions, Kalispell, Mont., says that he uses colored glass aggregates for concrete countertop and floor construction. He places them integrally for countertop construction and seeds them for floor work. For seeded work he takes the added step of soaking them overnight in polymer to increase the bond to concrete. Before the placement he removes the glass from the polymer and lets it dry to the point where it still feels a little sticky. He broadcasts the aggregate from planks to achieve the most even broadcast. If he can't do that he places the aggregate every 10 lineal feet during the concrete placement. He typically uses a pea gravel mix when he does glass aggregate work and some of these stones are revealed in the exposing process, adding a nice look to the finish.
What type of mix does Brickform use?
He typically uses a pea gravel mix when he does glass aggregate work and some of these stones are revealed in the exposing process, adding a nice look to the finish. Brickform Using a stencil to sandblast a pattern provides for crisp separations between the protected area and the exposed portion.
