Why Genicook Uses Borosilicate Glass (Instead of Plastic, Steel, or Regular Glass)

When it comes to cooking and food storage, the material you use matters more than most people realize.

At Genicook, we carefully tested and compared multiple materials before choosing the best option for our products. After extensive research, we selected borosilicate glass as our main material—because it delivers the best balance of safety, durability, and performance.

If you’ve ever wondered why borosilicate glass is considered premium, here’s exactly why we chose it.

 

What Is Borosilicate Glass?

Borosilicate glass is a high-quality type of glass made with silica and boron trioxide, designed to resist extreme temperature changes.

Unlike ordinary glass, borosilicate glass is commonly used in:

• laboratory equipment
• premium cookware
• heat-resistant food containers

That’s because it’s built to handle heat safely without breaking easily.

1. Borosilicate Glass Is Heat Resistant and Oven-Safe

One of the biggest advantages of borosilicate glass is its ability to withstand high heat.

Compared to regular glass, borosilicate glass has stronger resistance to thermal shock, meaning it can handle sudden temperature changes better.

This makes it ideal for:

• hot cooking environments
• reheating food
• storing hot meals safely
• oven-safe and microwave-friendly use (depending on the product design)

For Genicook, heat resistance wasn’t optional—it was essential.

2. Safer Than Plastic: No Chemicals, No Microplastics

Many people are now searching for alternatives to plastic food containers—and for good reason.

Plastic containers may degrade over time, especially when exposed to heat, leading to potential chemical release and microplastic exposure.

Borosilicate glass is naturally:

• non-toxic
• BPA-free
• non-reactive
• chemical-free

It does not absorb chemicals or release harmful substances into food.

That makes borosilicate glass one of the safest materials for modern kitchens.

3. Better for Food Storage: No Stains and No Odors

Plastic containers often absorb smells and stains. Foods like curry, tomato sauce, garlic, and spices can leave permanent marks.

Borosilicate glass is different.

Because it is non-porous, it resists:

• stains
• odors
• discoloration
• leftover smells

So your containers stay clean, fresh, and crystal-clear—meal after meal.

4. Stronger and More Durable Than Regular Glass

Not all glass is created equal.

Regular soda-lime glass is more likely to crack under heat stress or temperature changes. Borosilicate glass is engineered for strength and long-term use.

This makes it a better option for:

* daily cooking
* repeated heating and cooling
* frequent washing
* long-term durability

Genicook products are designed to be used every day—not replaced every few months.

5. Eco-Friendly and Sustainable for Long-Term Use

Many consumers are looking for sustainable kitchen products that reduce waste.

Plastic containers often end up in landfills, and even recyclable plastics are not always processed properly.

Borosilicate glass is:

• reusable for years
• recyclable
• long-lasting
• a great replacement for single-use plastic containers

Choosing borosilicate glass is a step toward a cleaner kitchen and a more sustainable lifestyle.

6. Premium Look, Cleaner Kitchen Aesthetic

We also believe that kitchen tools should feel good to use.

Borosilicate glass has a naturally premium appearance:

• crystal clear transparency
• modern minimalist look
• clean and elegant design

It makes food storage more organized and visually appealing, whether it’s in your fridge or on your countertop.

 

Borosilicate Glass vs Plastic vs Stainless Steel vs Regular Glass

Here’s a quick comparison of why borosilicate glass stands out:

Plastic

✔ lightweight
✘ may absorb stains and odors
✘ may release chemicals under heat
✘ degrades over time

Stainless Steel

✔ strong and durable
✘ cannot see food inside
✘ may react with acidic ingredients
✘ not ideal for microwave use
