Product Care & Maintenance

The same product looks a little bit different, is this a defect ?
Some of our products may vary in shape, color and texture due to the natural reactions of materials and different hand-made processes. At EILONG®, our design and aesthetic point of view, we appreciate the subtle variations between different pieces, which is the charm and beauty of crafted products.
Because those are going to be unique for us and for you.
If the ceramic or glass is damaged by small cracks, can I continue to use it until it breaks ?
Almost all materials have the phenomenon of thermal expansion and contraction.
Any cracks in ceramic or glassware will become the weakest point under the stress of heat and contraction and will widen until the cracks are completely broken.
Almost our products are designed for hot tea, coffee or hot food.
The effects of thermal expansion and contraction are evident.
If the product already cracked in any way and you continue to hold hot water, it may break in an instant.
So we remind everyone that if your tableware or utensils are damaged in any way, you should stop using them immediately.
And we believe this warning applies to all ceramic and glass tableware or utensils on the market.
Do you sell replacement parts ?**
We sell replacement parts for some products on our SPARE PARTS** page.


How to use and maintain porcelain properly ?
EILONG® porcelain products are usually designed in two main categories, pure porcelain or composite designing which combined with other materials.
Pure porcelain: EILONG® porcelain is always magnetized over 1260°C, so the dishwasher safe and microwaveable.
Composite design porcelain: Washing by hand is highly recommended, and should be used according to the instructions on each product page. When washing by hand, avoid using abrasive cleaners or steel wool.
When using in the microwave, do not overheat or heat without water.
What is meant by variation in glaze ?
Depending on the type of glaze, after high-temperature vitrification in the kiln, the minerals through oxidation will produce different color and texture changes.
Different glaze formulas with different kiln temperatures, each combination will produce its own unique effect, which is also the top secret of each factory.
Of course, the different origins of the porcelain clay, recipes and different kilns, the resulting glaze color, shades and texture will be slightly different.

Heat-Resistant Glass

How do I care for glassware items ?
EILONG® glassware is made of heat-resistant glass, and the products are dishwasher safe. When putting it in the dishwasher, store it in the upper basket to avoid applying force and weight. When washing by hand, avoid using abrasive cleaners or steel wool. It is also microwave safe. But don’t add water to cool down immediately after Dry burning.
If there are small bubbles in the glassware, is it a defect ?
No, due to characteristics of the material and manufacturing process, some glassware may contain tiny air bubbles and dots. However, they do not affect the quality of the product.
What does "maximum temperature differential" mean ?
With EILONG's heat-resistant glassware, we note that the "maximum temperature differential" is 150°C/302°F. This means that when the glass is cooled or heated rapidly, it can tolerate without breaking if the sudden temperature change is within the range of 150°C/302°F. This does not mean that 150°C/302°F is the maximum temperature limit.
Can glass teapots be heated on direct fire ?
Our glass products are made of the top-spec. borosilicate glass raw materials, any glass teapot or single-layer glass products, they can be directly heated by flame. But be sure to confirm that the product itself is not damaged or any small cracked, Otherwise there is a risk of heating burst.
