Premium Tier (La gourmet Pureglass / Premium Sets)

Pack Right. Eat Safe. Bake Effortlessly.

Why juggle separate dishes for meal prepping, oven baking, and fridge storage? This all-in-one premium borosilicate glass set transitions seamlessly from your kitchen counter to a high-heat oven, and straight into the refrigerator or freezer.

🌟 Why You’ll Love It

• True Borosilicate Glass: Unlike ordinary glass, high-grade borosilicate glass handles dramatic temperature changes without cracking or shattering.

• Stain & Odor Resistant: Tired of plastic containers turning orange from tomato sauce? Our glass bases never absorb odors, flavors, or stubborn food stains.

• Airtight & Leakproof Lids: The durable, food-grade lids lock in freshness and prevent accidental spills, making them perfect for busy meal-preppers and commuters alike.

• Smart Space-Saving Design: Nest them inside one another when empty, or stack them neatly in your fridge to completely maximize your storage space.

⚠️ IMPORTANT: Safe Cooking Guide

We believe in 100% transparency to keep your kitchen safe! Please follow this crucial guideline when using your new set:

🛑 REMOVE THE LIDS BEFORE BAKING: The glass bases are completely oven-safe and ready for your favorite lasagnas, roasts, and bakes. However, the storage lids are NOT oven-safe. To prevent the lids from melting, burning, or warping, always remove the lid entirely before placing the glass dish into the oven or microwave.

🌡️ Safe Temperature Limits 

• The Extreme Cold Limit: Down to -4°F (Safe for standard home freezers and refrigerators).

• The Maximum Heat Limit: Up to 752°F (The extreme structural limit of the raw glass).

• Safe Home Baking Limit: Up to 446°F to 450°F (The maximum temperature a customer should ever use in a standard residential kitchen oven).

🛡️ How to Word This Safely 

Product Care & Safety Guidelines

• Oven Safe: The glass base is safe to use in preheated ovens up to 450°F.

• Freezer & Microwave Safe: Perfect for cold food storage down to -4°F and safe for microwave reheating.

• ⚠️ Crucial Lid Safety: The airtight storage lids are NOT oven-safe and NOT microwave-safe. To avoid melting, burning, or damaging the lids, always remove the lid completely before heating or baking the glass dish.

• Thermal Shock Warning: While borosilicate glass is highly thermal-shock resistant, avoid extreme, instant temperature jumps—such as placing a freezing cold dish directly onto a blazing hot stove burner, or pouring ice-cold water directly into a scorching hot empty pan.
