Gold Flint Gravel

 

Gold flint gravel is a very efficient drainage medium often used around buildings in sizes between 30 – 20 mm.  Pleasing on the eye as well as practical, these pebbles offer a most versatile solution in a whole range of garden settings.  The pebbles are predominantly of greyish brown though with subtle colour tones typical of the flint family.  Flint has been well known to man since prehistoric times because of their quality to produce and retain a sharp edge when snapped.  These however have been rounded by the wave action mixing sand and water as a powerful abrasive on exposed storm beaches, smoothing the material into pebbles which nevertheless still possess the same qualities common to all the flint family, durability, brittleness and bright texture.  Rounded by the seas in which the chalk from whence they came was laid down in massive beds over countless eons of time, the silica is derived from the calciferous shells of tiny, microscopic organisms which gave rise to the chalk itself.

Commonly found in Southern England along storm beaches, gold flint gravel presents the landscape gardener with a material that combined well with many other materials, offering the potential to create a natural garden evocative of holidays spent beach combing.  Build on this effect by adding driftwood and splashes of bedding colour and the whole experience beckons amateurs to become professional landscape-sharpers, passionate in their pursuit of the perfect balance between the natural and the built environment.

Ruth asks…

I am going to use crushed red brick gravel?

for my guppies tank and my white cloud tank I bought the gravel from a pet store just wondering if anyone else has used this?

Martin Boyle answers:

Gravel is gravel, and if your thinking red brick gravel has any bad effects, it doesn’t.

Just plain gravel, nothing different from blue, multi colored, or black.

I used blue gravel, and went to more of a earth tone, and now Fluorite and Eco-Complete.

Sandy asks…

I am looking for information about landscaping stone gravel. What is a good inexpensive stone gravel?

I am unsure of what types of materials these refer to. I need an inexpensive quarter size or smaller type of stone gravel. #2a is regular driveway stone gravel right?

What do these mean?
2A Material (2A Modified=GABC=DGA)
AASHTO# 1 (Ballast)
R-3 Rip Rap
R-4 Rip Rap
R-5 Rip Rap
R-6 Rip Rap
R-7 Rip Rap
R-8 Rip Rap
Rustic Red AASHTO# 10 (Grit, Screenings)
Rustic Red AASHTO# 3 (“1½” Clean=”3A Clean”)
Rustic Red AASHTO# 57 (2B)
Rustic Red AASHTO# 8 (1B)

Thank you in advance for your time………

Martin Boyle answers:

I’m not sure about the 2-A material, but the last time I had stone gravel put on our driveway it was #57, about 3/4″ stone. #8’s are smaller. The ballast and rip-rap are all big rocks. The screenings are like sand and used for base material.

I find that 20mm to 40mm crushed quarry stone makes for a good foundation for a normal drive.

You will find crushed stone knits together and doesn’t spread when driven on.

The cheapest stone gravel will be the type your local rock quarry will use to mix in with there concrete mix.

These stone chippings will be guaranteed to be hard waring, as they only use hard waring stone like Granite and some sandstones, [for which there is an abundance] for concrete mixtures.

Red porphyry rocks are a more decorative stone which can be crushed down to a consistent 20mm size, ideal for a driveway. The only drawback is the cost.Compared to your cheaper gravel ,three times the cost, depending on the distance for haulage.

a. Chert

The most common siliceous rock is chert, which is a dense, micro crystalline rock composed of chalcedony and quartz. Chert is the second most abundant chemically precipitated rock after limestone. It occurs in beds and in nodules. Bedded chert consists of siliceous fossils such as diatoms and radiolaria, which form siliceous oozes on the sea…

Robert asks…

gravel ??/?

What would happen if i put normal builders gravel in my fish tank and if i did could i do something to it to make it OK or not thanks  🙂

Martin Boyle answers:

Gravel is gravel is gravel. Builders gravel, pretty much the cheapest you can buy, is assuredly JUST rock, no chemical treatments (the reason aquarium gravel is so much more expensive is because of the ridiculously gaudy epoxy coat on it). Buying straight gravel is about as safe as you can get, and I would strongly encourage you to do so… Just be sure the package doesn’t say that it was treated in any way.
