Introduction
This standard Ceramic Love Languages Mug (featuring “I love you” in multiple languages) served as our control for comparisons against the ZWILLING Sorrento Plus and BTaT Glass insulated double wall glass mugs. Because it’s a typical single-wall ceramic design (no double-wall or vacuum insulation), the heat retention and exterior temperature readings provide a baseline for how quickly a non-insulated mug behaves in real-world use.
Test Setup
Thermal Imaging: We used infrared (IR) photos to measure surface temperature changes over time.
Elevation: 4,400 feet above sea level (At this elevation, the boiling point of water is 204°F rather than 212°F at sea level.)
Water Temperature: 204°F (Boiling)
Ambient Temperature: 66°F
Observation Duration: 40 minutes
Key Temperature Readings and IR Photos
- Empty (Ambient)
- 66.3–66.8–66.1°F
- The mug’s baseline temperature matched the ambient environment before filling.
- Pouring
- 92.4 (interior rim) –73.7–131.0°F
- As the near-boiling water (204°F at 4,400 ft) enters, the mug’s interior and lower walls heat first, while the top remains cooler.
- 30 Seconds
- 162.7–154.4–170.7°F
- Rapid heat transfer to the mug’s outer surface; handle still noticeably cooler.
- 1 Minute
- 168.1–168.1–170.2°F
- Exterior temps remain near their initial peak.
- 1 Minute 30 Seconds (Max Recorded Temperature)
- 171.0–171.9–167.6°F
- This interval shows some of the highest surface readings observed.
- 2 Minutes
- 168.1–171.7–169.8°F
- Still extremely hot to the touch on the mug body.
- 2 Minutes 30 Seconds
- 166.9–170.9–168.5°F
- Slight cooling in some areas, but temperatures remain high overall.
- 3 Minutes
- 164.4–169.4–167.2°F
- A modest dip from the 2-minute mark; the mug is still quite hot.
- 3 Minutes 30 Seconds
- 163.2–168.0–166.0°F
- Cooling continues gradually; top rim often reads a bit lower than the center.
- 4 Minutes
- 161.7–166.7–164.6°F
- Still very warm; handle remains the safest grip point.
- 4 Minutes 30 Seconds
- 160.2–165.4–163.3°F
- Consistent cooling pattern; the body is dropping about 1–2°F every 30 seconds or so.
- 5 Minutes
- 158.9–163.9–162.0°F
- The mug remains hot, but no longer at its peak.
- 10 Minutes
- 147.4–152.0–151.4°F
- A more noticeable drop; still above 145°F at the hottest points.
- 20 Minutes
- 131.3–135.4–135.0°F
- Well below initial peak, though the beverage inside remains warm.
- 30 Minutes
- 119.5–123.3–122.8°F
- Contents and exterior are comfortably warm, but not piping hot.
- 40 Minutes
- 114.3–116.4–115.4°F
- Exterior and interior temperatures still dropping. End of testing time.
Analysis & Observations
Baseline for Comparisons
These readings show how a non-insulated ceramic mug performs under standard conditions. Future tests on insulated mugs will highlight how double-wall or vacuum-sealed designs differ in retaining heat (and keeping the exterior cool).
Rapid Heat Transfer
As a typical ceramic mug, it lacks the insulating properties of double-walled or vacuum-sealed cups. Heat moves through the mug’s wall quickly, making the exterior quite hot early on (over 170°F at peak).
Gradual Cooling
By 20 minutes, the exterior temperature has dropped roughly 35–40°F from its peak. After 30–40 minutes, it hovers around 114–116°F, which is still warm to hold but significantly cooler than the initial spike.
Handle vs. Mug Body
The handle remains cooler than the mug’s body for most of the test—useful if you want to avoid burning your fingers when the mug first hits 170°F on the outside.
Pros & Cons
Pros
- Familiar & Simple: Easy to use and clean, just like any classic ceramic mug.
- Comfortable Handle: Helps prevent burns when the exterior is very hot.
- Great Baseline: Offers a clear control for comparing advanced or insulated designs.
Cons
- Exterior Can Get Very Hot: Surface temps spiked above 170°F, requiring caution.
- Faster Heat Loss: By 30–40 minutes, contents have cooled significantly compared to an insulated mug.
Final Thoughts
This Ceramic Love Languages Mug is perfect for everyday use but also serves as an excellent control experiment. Its single-wall construction shows us exactly how quickly heat transfers to the mug’s exterior—and how fast your beverage cools—when there’s no added insulation. If you’re looking to maintain piping-hot coffee for longer or keep the exterior safe to the touch, an insulated mug would outperform this model. But for a standard, sentimental mug, it does its job just as you’d expect a classic ceramic cup to do.
