Borosilicate glass will begin softening above 800 °C (~1500 °F). Any temperature below this should be a good operating temperature;<br>2. The temperature differential that borosilicate glass can withstand before fracturing is about 165 °C (329 °F).<br><br><b>PACKAGE</b><br>Young4us Glass Erlenmeyer Flasks x 3<br>Young4us Rubber Stoppers for Erlenmeyer Flask x 3
