All Mayco products are designed and factory tested to meet our standards of quality and performance. We guarantee that every product we ship will perform in accordance with our recommended usage guidelines and we will replace any product that is proven defective because of manufacture at no cost.
It is the responsibility of the end user to determine the suitability of a product for any non-standard use. We strongly recommend the test firing of glazes and/or application techniques new to the user, especially in commercial applications where large production quantities are involved.
Mayco color products (glazes and acrylics) & most accessory products are manufactured in our Hilliard, Ohio facility. We warranty our color and accessory products for two (2) years from their manufacture date.
Each color product label bears a 7-digit manufacture code, printed above the UPC bar code. The first two digits after the “#” indicate the year of manufacture, the third and fourth digits denote month of manufacture, and digits 5-7 represent the batch produced during the given month. For example: Lot#0712055 was produced in the year 2007, the month of December, and it was the 55th batch produced that month.
Product warranty claims should be directed to the distributor and/or dealer from which you purchased the product, and you will be required to provide this manufacture code.
