These grenware large bowls by ecosource are made primarily from grain husks. They are lightweight with a similar feel to plastic, but much more attractive and petroleum free. They are durable enough for outdoor use, yet elegant enough for the dining room. The lighter brown bowl (natural) is the natural color without dyes or bleaches; the dark chocolate brown color (cocoa) is achieved through the addition of ground coconut shell. The bowls can be cleaned in the dishwasher, however, this may shorten their lifespan somewhat and etching may occur with regular dishwasher use. They are not recommended for the microwave (reportedly, if you leave them in too long you will detect a burning smell). According to ecosource, the bowls will last about five years before showing wear and tear, at which time they can be composted. This large deep bowl measures 8.5 inches in diameter, a nice size for serving a side dish or a meal-sized salad. Since this bowl is made from natural materials, please appreciate that some variations may occur. Made by a family-owned business in China.

Note to composters: Ecosource has indicated that they have 3rd party tests for biodegradability from an independent laboratory, but these bowls have not been certified as compostable. According to ecosource composting these bowls requires about four months in a good working compost (i.e., you need plenty of microbes to do the job).
