Our signature bowls are designed to float within the CopperCore (Patent Pending) Oven for a convection-based estratto. Our bowls have temperature sensitive snap disks, which allow you to accurately and repeatedly roast your herb to your desired level of estratto. 

Full Bowl Capacity 0.1 grams (At a Reasonable Pack) 

Half Bowl Capacity 0.05 grams (At a Reasonable Pack) 

XL Bowl Capacity 0.2 Grams (At a Reasonable Pack) 

*We do not recommend overpacking, as this is a convection-based device that favours airflow for a full estratto*
