Clay can contain air bubbles which contain water. When the clay is fired, the heat rapidly expands that water vapor, causing the piece to explode. Therefore, clay pieces should be hollow, with a hole for expanding air and water to escape.
yes because they can withstand heat and cold but not smoke or fumes and this is how we know they are good indicators of air quality
because there are variety of life that can withstand the heat and some bacteria that removed carbon dioxide in the air...
A 200 liter steel barrel can typically withstand a maximum air pressure of around 100-150 psi (pounds per square inch) before failing. It is important to follow manufacturer specifications and not exceed the recommended pressure limits to ensure safety and prevent damage to the barrel.
It is not recommended to mix air dry clay and polymer clay together as they have different properties and curing methods. Air dry clay dries by exposure to air, while polymer clay requires heat to cure properly. Mixing them may result in uneven drying and potential breakage of the final project. It is best to use them separately for best results.
Hot air balloons are typically made out of nylon fabric coated with a heat-resistant material like polyurethane or silicone. This material is lightweight, durable, and able to withstand the heat generated by the burner that inflates the balloon with hot air.
Rule of thumb is no more than 50 feet.
