Terracotta pots are quite sturdy until you try to cut or puncture them, which presents a problem if you plan to turn an ordinary terracotta pot into a tajine pot, a lantern for the porch or patio, a " fairy garden", into a frog terrarium or whatever your creativity suggests.For this reason, before you approach your pot with a saw, grinder or drill, read the answers listed below for key questions you may have.This way you can increase your chances of getting excellent results, rather than piles of pottery shards that were once beautiful vases.

Question 1 of 9:

What tool should I use?

1
Use a circular saw (such as a Dremel) to cut small pots. It can't cut through terracotta like butter, but it will get the job done.For best results, use the Dremel bit fitted with a diamond blade (or the similar attachment that comes with the cutting tool you are using).Below are some of the tips you need to keep in mind:^{[1]

- Wear work gloves, protective glasses and a dust mask.
- Immerse the vase in water for about 20 minutes so that less dust is produced during cutting.However, it will be a job that will create a lot of dust and mess, so it is always best to do it outdoors.
- Clamp the vase in a bench vice to stabilize it during the cutting phase (be careful not to tighten the vice too much otherwise the vase will break).
- Turn on the circular saw, then gently place the rotating blade on the surface of the pot.Apply even, steady pressure, rather than trying to force the blade into the terracotta.Score the surface of the vase (you can also go from side to side), then move the blade slowly along the line of the cut.
- Pour or spray water regularly where you are cutting in the pot to prevent the terracotta from overheating.
- Very carefully, eliminate any sharp edges along the cut by sanding them with 80-grit sandpaper.

To cut large pots, use an angle grinder. The cutting technique to use in this case is almost identical to that of using a circular saw, but the angle grinder is much larger and more powerful.Make sure you wear all the necessary protective gear, soak the vase in water to reduce the amount of dust that will be produced, cut the vase using light, even, consistent pressure, then remove any sharp edges using sandpaper.^{[2]

- Unlike a circular saw or a Dremel which can also be held with one hand, the angle grinder must be held and controlled with both hands.Clamp the jar in a bench vice, being careful not to tighten it too much, so that you have both hands free to hold the grinder safely.
- A diamond blade will ensure excellent work, but you can also use a cutting wheel for stone and concrete.
- The angle grinder produces a large amount of noise when operating, so it is advisable to also wear protective headphones.

Use a hacksaw with a tungsten carbide blade. This is an effective alternative albeit a little slower.If you have the time and physical stamina to cut the vase by hand, you can opt to use a hacksaw equipped with a tungsten carbide blade.Blades of this type have an action very similar to that of sandpaper, rather than that of a blade with metal teeth.Again, as with power tools, immerse the jar in water, wear all the necessary safety equipment to preserve your physical safety and clamp the jar in a vice for best results.Make the cut using long, regular movements back and forth to use the full length of the blade, applying constant, sufficient pressure to advance along the section of the cut.^{[3]

- If you need to replace the hacksaw blade, loosen the wing nut near the handle by turning it counterclockwise.Remove the old blade by sliding it off the two clips at the end of the hacksaw, install the new blade and tighten the butterfly nut by turning it clockwise.

Question 2 of 9:

What tools Not should I use?

Avoid using circular or hand saws with toothed blades. The larger the metal teeth of the blade or cutting disc, the greater the risk of chipping the terracotta and breaking the vase.Always opt for tools that perform a milling action on the terracotta, rather than scratching it.^{[4]

- Regardless of the tool you choose to make the cut (a circular saw, an angle grinder or a handsaw), always choose a diamond or tungsten carbide blade or cutting wheel.These cutting tools are designed to have a milling action on materials such as glass, concrete or stone.

Question 3 of 9:

How do I cut the bottom of the vase?

Slowly slide the circular saw blade or cutting disc of the angle grinder around the circumference of the bottom of the jar. Regardless of whether you decide to make the cut freehand or draw a line to follow, cut the vase at least 2-3 cm from the bottom to reduce the chance of breaking it.Score the surface of the vase by creating a small groove using the cutting tool you have chosen to use, rotate the vase slightly and make a new incision that follows the previous one, then repeat the process until you have completed the cut.^{[5]
X
Research source}
- If you are using an angle grinder, you will most likely need to make 1-2 passes to be able to completely cut through the bottom and remove it from the rest of the jar.In the case of a portable circular saw or a Dremel it will take 2-3 passes.
- To make a more precise cut, clamp the vase in a table vice.However, if the precision of the cut is not a determining factor, you can simply place it on the ground on its side.

Question 4 of 9:

Can I cut the vase exactly in half?

Download PDF

Yes, score the surface of the vase along the cut line using the saw or grinder, then separate it in half gently and carefully. Draw a line that divides the vase exactly in half, clamp it in a table vice with the side facing up.Now score the surface of the vase along the line you drew using the tool you chose.Apply light, even pressure while cutting.Try to create an incision that reaches about half to 2/3 of the thickness of the terracotta.After you complete the cut, the vase should split in half on its own when you apply light pressure.If not, tap it gently along the cut line using a small rubber mallet or similar tool.^{[6]

- Cutting terracotta from side to side using a circular saw or angle grinder is very likely to shatter the pot.
- The cut will not be clean and clean, so be very careful of rough edges as they will be extremely sharp.

Question 5 of 9:

Can I create embossed or engraved decorations?

1
You can create a decorative engraving using a portable hand engraver. Clean the surface of the vase and immerse it in water, then use a stencil (or draw the engraving subject freehand) to transfer the engraving design directly onto the vase.Put on your full safety equipment, work gloves, safety glasses and dust mask, then turn on the engraver.Use a thin tip (about the size of a pencil) to score along the lines of the design to the depth you want.At this point, remove any dust residue using a clean cloth.^{[7]

- Tools made by Dremel are a great option for this type of work, but not the only one.
- Consider clamping the jar in a bench vise to hold it steady while you work on the incision.

Also use the hand engraver to remove excess terra cotta present in the engraving and bring out the finished design. The only difference compared to before is that you will now have to use the tip of the engraver to remove all the excess terracotta and, if necessary, pierce it completely.At this stage you can use both the tip of the engraver's cutter and the sides to complete the engraving design.The high rotation speed of the engraver tip is perfect for rounding and beveling the edges of the engraving, but you may still need to use sandpaper when you finish the job.^{[8]

Question 6 of 9:

What should I do if I need to create a hole?

Drill a hole carefully and gently using a small concrete or stone bit, then use a larger bit to widen it. Immerse the vase in water for at least 20 minutes (or overnight) to soften the terracotta and reduce the dust that will be created during work.Place two pieces of masking tape in an X shape over the location where you need to drill the hole.Attach the smallest concrete bit you have to the drill, then gently and slowly drill a hole into the terracotta.Apply enough pressure to the drill bit to prevent it from moving away from where you need to drill the hole.^{[9]

- If necessary, use a bit larger than the first to widen the hole you created.Continue this way to get a hole the size you want.
- To avoid hurting yourself from the terracotta splinters that will be produced, wear protective glasses and work gloves.
- Remember to let the drill bit do all the work.If you apply pressure to finish sooner or to try to facilitate the drilling process, you risk chipping the terracotta.

Question 7 of 9:

How do you break a vase in case of need?

Use a piece of wood and a hammer to break the vase in a controlled manner. Wear protective glasses, work gloves and long clothing that protects your arms and legs from terra cotta debris.Place the piece of wood (which can be a piece of regular wood plank) against the top inside wall of the pot where you want to break it and hold it in place.At this point, hit the outside of the vase with the hammer exactly where you placed the piece of wood.This way, you will most likely break a large fragment of the wall of the vase and also get smaller pieces.^{[10]

- Cover the pot with a towel as additional protection against any terracotta splinters that may be produced during work.
- Maybe you're wondering why you would ever need to break a vase;however, there are many DIY projects where a broken vase is needed.For example, it is becoming very popular to create a "fairy garden" inside a broken terracotta pot.
- If you're trying to make a "fairy garden," your goal is to remove a portion of the pot's wall while leaving the bottom intact.

Fill the vase using the terracotta fragments, some soil, add the plants and complete the work with the typical decorations of a "fairy garden". Fill the pot to about 1/4 of its capacity with soil, then place the pieces of terracotta that you obtained from breaking the pot and add more soil to create walls, sloped areas and a spiral staircase.Now add some miniature plants (such as baby's teardrop and trichostema lanatum), a small fairy house, a castle or any other decorative element you want.^{[11]

- You can purchase decorations suitable for your "fairy garden" online, in DIY and DIY stores or even in stores that sell aquariums and related accessories.
- If you need inspiration, do an online search using the keywords "garden fairies broken vase".Some of the examples you will find are really beautiful.

Question 9 of 9:

I broke a vase, what can I do?

Don't just throw it in the trash, try to reuse it. If the pot has broken too much to be able to use it to make a "fairy garden", look for another way to use the pieces of terra cotta you obtained.For example, you can use them to fill the bottom of other pots that you will use for your plants in order to facilitate water drainage.Or place terracotta shards at the base of the plants to prevent squirrels from digging holes in search of food.^{[12]

- The fragments you made from the top edge of the pot are perfect to use as descriptive labels for the plants you have in the garden or at home.You will simply have to write the name of each one on it and then plant the piece of pot in the ground.
- Be very careful.The edges of terracotta shards can be very sharp, so handle them with care.
