Did You Know?
1. The process of drilling through glazed pottery requires the use of a diamond-tipped drill bit, due to its durability and ability to cut through the hard surface.
2. Interestingly, in ancient China, the technique of drilling glazed pottery was developed during the Tang Dynasty (618-907 AD). The pottery was often adorned with intricate designs, and drilling holes through the glazed surface allowed for the creation of functional objects like vases with removable lids.
3. There is a delicate balance to be maintained while drilling glazed pottery. Applying too much pressure or drilling too quickly can cause the pottery to crack, while insufficient pressure may prevent the hole from forming altogether. Proper technique and a steady hand are essential.
4. The water used while drilling glazed pottery not only serves as a lubricant but also helps prevent the pottery from overheating. The water cools down the drill bit and pottery, preventing any damage or discoloration caused by excessive heat.
5. While glazes are typically known for their smooth, glossy surface, some forms of early Chinese glazed pottery featured a technique called “crazing.” This intentional cracking of the glaze created an aged appearance and added artistic value to the pieces. Drilling through crazed glaze requires extra care, as the cracks can make the pottery more fragile.
Using Water As A Lubricant
When drilling through glazed pottery, it is crucial to use water as a lubricant to prevent overheating and cracking of both the material and the drill bit. The heat generated during drilling can cause the glaze to crack, ruining the pottery piece. To avoid this, make sure to keep the surface of the pottery moist at all times.
Before starting the drilling process, fill a small container with water and have it ready by your side. It’s also a good idea to have a sponge nearby for easy access to water. As you begin drilling, periodically dip the drill bit into the water or squeeze water from the sponge to keep the area being drilled wet. This will help dissipate the heat and prevent any potential damage.
Starting At Lowest RPM
To ensure the best possible outcome when drilling glazed pottery, always begin the drilling process at the lowest RPM (revolutions per minute) available on your drill. Starting at a slower speed will help you gain better control over the drilling and minimize the risk of the pottery cracking or shattering.
Additionally, starting at a low RPM allows the drill bit to gradually penetrate the glazed surface without putting excessive pressure on it. This approach is particularly important when drilling through delicate pottery pieces or intricate designs. By starting slow, you can reduce the chances of damaging the pottery and increase the likelihood of a successful drilling outcome.
- Start the drilling process at the lowest RPM available on your drill
- Gain better control and minimize the risk of cracking or shattering
- Gradually penetrate the glazed surface without excessive pressure
Note: It is crucial to exercise caution and patience when drilling pottery to achieve the desired results.
Angling Drill On Masking Tape
Another helpful technique when drilling glazed pottery is to angle the drill on masking tape for added stability. This technique provides extra support to the drill and prevents it from slipping or wandering off course during the drilling process.
Start by applying a strip of masking tape to the surface of the pottery where you intend to drill. Position the tape at a slight angle, pointing towards the direction you want to drill. Then, firmly press the drill against the tape, ensuring it is secure and won’t shift while drilling.
The masking tape acts as a guide, stabilizing the drill and preventing it from skidding on the smooth glazed surface. This technique helps improve accuracy and control, enabling you to drill precisely where you intend.
Applying Water With Sponge
- The drilling process can be made more effective by using water from a sponge to keep the surface of the pottery moist.
- This helps to prevent any potential damage due to overheating and keeps the pottery cool.
- To ensure continuous moisture, pause periodically during drilling and use a sponge to moisten the specific area being drilled.
- Gently squeeze the sponge to allow water droplets to fall onto the spot where the drill bit is making contact.
- This continuous application of water will prevent the glazed pottery from getting too hot and minimize the risk of cracks or fractures.
Returning To Vertical Position
Once you have successfully cut into the glazed pottery with the drill, it is crucial to return the drill to a vertical position. This step is important to maintain stability and avoid any unintended damage or disruption to the pottery piece.
When returning the drill to a vertical position, be mindful of your movements and maintain a steady hand. Any sudden shifts or tilting of the drill can potentially cause the drill bit to break or chip the pottery. Slowly withdraw the drill from the hole while keeping it vertical until it is completely removed from the pottery.
Taking the time to ensure a proper vertical withdrawal is essential for maintaining the integrity of the glazed pottery and achieving a clean drilling result.

- Slowly withdraw the drill while keeping it vertical
“Taking the time to ensure a proper vertical withdrawal is essential for maintaining the integrity of the glazed pottery and achieving a clean drilling result.”
Drilling Slowly And With Little Pressure
Lastly, it is crucial to continue drilling through the glazed pottery slowly and with minimal pressure once you have penetrated the surface. Applying excessive pressure or drilling too quickly can cause the pottery to crack or break, resulting in irreparable damage.
Maintain a steady and controlled drilling motion, allowing the drill bit to cut through the material at its own pace. Applying too much force or rushing the process can lead to accidents that could ruin your pottery piece.
By drilling slowly and with little pressure, you give the glazed pottery time to withstand the drilling process without compromising its structural integrity. This approach will help you successfully navigate through the material while preserving the quality of your pottery.
In conclusion, drilling through glazed pottery requires careful attention and adherence to specific techniques. Using water as a lubricant, starting at the lowest RPM, angling the drill on masking tape, applying water with a sponge, returning to a vertical position, and drilling slowly and with little pressure are crucial steps to achieve success in this process. By following these guidelines, you can ensure the preservation of your pottery while creating the desired hole or cut.
