No. Rock Paper is not intended to replace the paper your are currently using. It’s an addition to what you already use.

Think of it as having a collection of colored pencils and a collection of markers. They both make a mark but they have very different properties.

Rock Paper is another type of paper that has different properties and can be used for some projects and not others. After all, you typically wouldn’t use watercolor paper for your Origami projects.

We have had the most success with:

1. Hot glue

2. Tape

3. Loctite Plastics Bonder

We are continually testing new ways to bond sheets of Rock Paper together and will update this page with new discoveries.

1. scissors

2. utility knife

3. scalpel

4. cutting machines (like Cricut)

Rock Paper will not dull your blades any faster than other papers will.

We have not tested Rock Paper in laser cutting machines.

Yes and Rock Paper is acid free, mildew resistant, mold resistant and bug resistant.

The main ingredient is calcium carbonate and we use a proprietary binder. We do not use water in the process of making Rock Paper so therefore no waste water. No harmful chemicals are involved. All the ingredients that make up its properties are what make it waterproof. It is a sustainable process.

We do not recommend burning Rock Paper. Burning any type of paper can cause injury or property damage.

Unfortunately, printer ink does not fully dry on Rock Paper and will smear.

Many different types of inks and even graphite work great on Rock Paper.

Just a few examples of the pens, markers, pencils and inks I’ve tried are:

1. Permanent markers

2. Colored pencil

3. Ball point pen

4. Gel pen

5. Pencil

6. India Ink

7. Alcohol ink

8. Block printers ink

And the best part, markers and inks do not bleed through!!

Yes, and it has an impeccable fold memory. The thinner sheets work really well for Origami.

it will maintain its color for a long time. As long as it is not in persistent direct sunlight. We have pieces at least 10 years old that are as vibrant as the day they were made.

According to Mirriam-Webster dictionary the definition of Lightfast is:

“resistant to light and especially to sunlight”

The short answer: Yes

The longer answer with further explanation:

WE USE MILLIMETERS TO DESCRIBE THE THICKNESS OF ROCK PAPER INSTEAD OF POUNDS

Typically, when paper thickness is determined it’s weighed in a ream of 500 sheets that has been cut into a predetermined size based on the paper type.  The more paper weighs the thicker it is.  However, this way of measuring does not work for Rock Paper because in general Rock Paper is heavier (remember it’s made from rocks).

To test our theory we ran a small experiment.

Experiment results:

1.     We cut a thin sheet of Rock Paper to match the size of a standard sheet of Origami paper.  Both Sheets are 6x6 inches square.

2.     We measured the thickness of each sheet

a.     Rock Paper was 0.076mm thick

b.     Origami paper was 0.078mm thick

3.     We weighed each sheet individually

a.     Rock Paper was 0.075oz

b.     Origami paper was 0.041oz 

The results show us that even though the sheet of Rock Paper was 0.002mm thinner it still weighed more than the standard sheet of Origami paper by 0.034 ounces.  This data shows that using pounds to measure the thickness of rock paper will give confusing numbers.

For good measure, we did another experiment using 110lb cardstock and Rock Paper that had a similar thickness.

Experiment results:

1.     We cut a thick sheet of Rock Paper and a sheet of 110lb cardstock to 6x6 inches square.

2.     We measured the thickness of each sheet

a.     Rock Paper was 0.225mm thick

b.    Cardstock was 0.239mm thick

3.     We weighed each sheet individually

a.     Rock Paper was 0.16oz

b.    Cardstock was 0.16oz

The results were interesting in that both the thick Rock Paper and cardstock weighed exactly the same.  However, if you look at the thicknesses, the cardstock was slightly thicker still proving the point that Rock Paper in general is heavier than fiber-based papers. 

No. The color you see in Rock Paper is a pigment added during production, unlike most fiber/pulp based papers who add color dyes after the paper is already made.

No, not even a little bit. Rock Paper is non-toxic. But, just like any paper type, Rock Paper should not be put in your mouth and you should never swallow it.

Amazingly enough it feels similar to fiber/pulp based papers. Some sheets are very smooth and others have a slight texture.
