Longdrink glass Istanbul, Pasabahce - 380ml

Question : Hello, I am interested in purchasing the Pasabahce Istanbul Longdrink Glass 380 ml in larger quantities. I plan to use the glass as a container for poured candles and would like to confirm a few technical details before placing an order. Could you please clarify the following: What is the maximum recommended temperature the glass can safely withstand? Is the glass standard soda-lime glass, or does it undergo any additional strengthening process (such as heat strengthening or tempering)? Is the glass suitable for hot liquids or thermal shock (for example, dishwasher-safe or hot-beverage-safe)? Are the diameter and height dimensions consistent across production batches? Is the glass machine-pressed and annealed during production? Thank you very much for your assistance. Best regards, 

From : customer

Answer:

Technical information regarding the Pasabahce Istanbul Longdrink Glass (380 ml)

Based on available product specifications for the Pasabahce Istanbul Longdrink Glass 380 ml, the following technical details can be confirmed or reasonably inferred:

1. Maximum recommended temperature
The manufacturer does not publish a specific maximum temperature rating for this model. The glass is made from standard glass rather than heat-resistant laboratory or borosilicate glass, so it is generally intended for cold or room-temperature beverages. It is dishwasher-safe, which indicates it tolerates typical dishwasher temperatures, but it is not specifically rated for high-temperature applications or direct pouring of very hot liquids such as melted wax without testing.

2. Glass type and strengthening process
The glass is described as standard clear glass (“normal glass”) and not tempered or heat-strengthened.
This means it is most likely standard soda-lime glass, which is typical for beverage glassware.

3. Suitability for hot liquids or thermal shock

• The glass is dishwasher-safe, indicating resistance to typical cleaning temperatures.

• However, since it is not tempered or borosilicate, it is not specifically designed for thermal shock or boiling liquids.

• Rapid temperature changes (e.g., pouring very hot wax into a cold glass) may cause stress or cracking.

4. Dimensional consistency
Typical nominal dimensions reported by suppliers:

• Height: approx. 14.5–15.0 cm

• Diameter: approx. 6.7–6.8 cm

• Total capacity: 380 ml (usable filling volume ~330 ml)

Manufacturing tolerances of ±5 % are considered standard for glass production, meaning small variations between batches may occur.

5. Manufacturing process
The glass is listed as machine-manufactured drinking glassware.
In industrial glass production, this normally implies:

• Machine pressing or forming

• Followed by annealing (controlled cooling) to relieve internal stresses before packaging.
