Mayco Fundamentals® Underglazes

Underglazes were the first product line Mayco produced in 1954 and continues to be a staple for many ceramic artists. Mayco Fundamentals® Underglazes are highly versatile – use for complete coverage or in design, apply to clay or bisque –  with a broad firing range of cone 06 to cone 10. Fundamentals® Underglazes serve equally well for the student making their first pinch pot and the clay artist creating works for a gallery.

PLEASE CLICK THE "TAX EXEMPT STATUS" LINK above and follow the instructions.

We aim to provide excellent customer service to all potters who chose to shop with us, however, the areas we are able to serve best are in Kansas, Missouri, Nebraska, Iowa, Arkansas, Oklahoma, and Illinois.  There are lots of great clay suppliers nationwide that probably do a better job of serving customers in states further away.  If you would like help finding a local supplier, please let us know.  We will be happy to assist you.  

Please note that we favor long term relationships with our customers over one-time transactions on our website based on a random google search result.  We are not Amazon and don't want to be.  We're a bit old-fashioned I guess...but with a website.  

This is a 40 year old family business, now being run by the second generation.  We generally run on a staff of 10 or less, and we all work really hard.    All employees here are treated like family...we DO also think of our customers as family, but that does mean if you are "tormenting" one of our "little brothers or sisters", we'll "ground" you.  

And if you're *really* naughty, you might get a policy named after you.  So just be nice, ok?  You be nice to us, and we'll do our best for you!  That's a promise.
