Use terracotta for a touch of natural beauty in garden spaces. While the high firing temperature and quality of their glazed and terracotta containers result in a durable and frost-resistant product, they still recommend that they are stored in a frost-free covered area in winter. If left outside, water may accumulate in the container and freeze, causing the planter to crack and break. Planters that must be left outside should be covered to prevent water, snow, and ice from accumulating inside the planter. Their glazed and terracotta pottery is high fired between 990 (terracotta) and 1000 (glazed) degrees centigrade to ensure frost resistance and durability. Due to the processes used in the manufacturing of their hand-made and hand-glazed containers. The glazes on their containers consist of natural, not chemical, components and therefore the final color of the product will vary. This process creates the unique beauty of each piece.
