Our fibreclay containers are produced by a patented process that makes it possible to create products that are lightweight, durable, water-resistant and aesthetically pleasing, using clays and other naturally-found materials. The energy usage in this process is only 10% of any other ceramic or plastics process. Fibreclay products are frost- and UV-resistant as well as non-flammable. Naturally retained salts will ensure an organic aging of the containers (Drainage holes should be drilled for outside use in the marked locations to ensure adequate drainage.) Fibreclay planters come in a wide variety of shapes and sizes, with either decorative or plain finishes.
