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. 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.

Braintree Supply Store (E-Mail Braintree):
Please place your orders at least one day ahead of time. It is easiest if you email a list of the items you are looking for to braintree@portlandpottery.com. We will call you as soon as your order is pulled and ready for pick up. Our Braintree store still remains closed to foot traffic, but you can still place orders for curbside pick up. We will not be able to fire kilns at our Braintree location until further notice. We apologize for any inconvenience.

In calculating linear coefficients of expansion (c/exp), Hall [JACS, 13(3) 194 (1930)] factors were used whenever available. M&H factors were used
otherwise. To transpose to decimals, multiply by 10-6. When available, measured expansion values are also presented as an aid in the practical use of these
Fusion and Flow temperatures shown are those used by the frit Control Department in quality control testing procedures. The Fusion temperature used are
somewhat higher than the actual softening points of the frits, and the Flow temperatures are those selected to allow for a valid comparison of flow
characteristics of a frit sample versus the established “Standard” for that frit.
The code numbers used to indicate percent oxide composition range for each frit are as follows:
1 = Present, but less than 5%. 2 = 5% to 15%. 3 = 15% to 25%. 4 = 25% to 50% 5 = over 50%.
