A note to our customers. This year has been very challenging. Thank you for your patience and commitment to the products and services we provide you. During the Covid-19 pandemic we have been hit with a number of set backs that have slowed the processing of most orders. This includes a reduction in staff, following the recommended CDC guidelines, and manufacturing and shipping delays for all ceramic materials and equipment from our vendors. Despite these circumstances we are working hard to come up with creative ideas to quicken our response and get your orders to you as soon as we can.
