6NOTE: I use the cauldron in conjunction with the punch bowl because sometimes guests will have a little too much to drink and I am afraid that they will swallow a large chunk of dry ice, so I put regular ice in the punch bowl and sit it on top of the cauldron which holds the dry ice to give the smokey and spooky effect or I may place regular ice in a separate bowl and place it near the punch.
Dry ice will sink to the bottom of a drink "cauldron". If more cooling is needed, do not add regular ice to the cauldron, instead add it to individual drink glasses. Do not allow dry ice to come in contact with bare skin or other bodily tissue. Keep the dry ice in its packaging at all times. Dry ice has a temperature of -79°C and direct contact can cause freeze burns. If you must handle dry ice, use heavy duty gloves. Always handle and store dry ice in well ventilated areas. Carbon dioxide gas is heavier than air. If it is allowed to accumulate in poorly ventilated areas such as boat holds, cellars, cars and vans, it can become a safety hazard, as it will displace oxygen and could lead to asphyxiation. Do not leave coolers in closed vehicles for extended periods and always make sure a window is open. Adequately ventilate areas before entering.
Do not place dry ice in airtight containers such as stoppered glass jars, bottles or other sealed containers as they could explode.
Do not store dry ice in refrigerators or freezers. Store in the best insulated cooler possible.
Do not pack dry ice in direct contact with glass bottles, jars, etc. as the glass could crack and shatter; use non-glass containers.
If the block is to be reduced in size by breaking or cutting, leave it in the packaging provided to avoid contact with skin and eyes.
Do not use dry ice in individual drinks. Use only in large punch bowls for effect. Under no circumstances should dry ice be placed in the mouth.
