Marinite Board

Post by quill »

I just ordered dome stuff from Thompson Enamels & I noticed they had various sizes of 'Marinite Board' for sale.

I am not familiar with this & was wondering, is it useful in fusing, say for slumping molds or as a kiln shelf?

I'm surprised to hear that Thompson would be selling Marinite. It warps pretty badly at the temps we work at.

It was advertised for use with enamels not fusing, I just wondered if it would work with fusing.

Thompson enamels mature around 1400ºF which is similar to fusing. I wouldn't spend my money on another marinite board.

A local shop used it for annealer doors. They won't use it again. They had 2 theories, either they fitted it too tightly, or it was just C**p. Either way it cracked badly, though it has not failed.

I tried it for a 24x55 kiln shelf years ago. It warped like a pototo chip, blistered, and cracked .... not all on the first firing. Pretty much sucks for anything above low-fire enamels 1100-1200 degrees. The factory couldn't believe it, since it is rated much higher (2,000?) and did replace the 4x8' sheet....which also failed. I still have one more piece leftover. I'm waiting for someone really smart to tell me how to use it without these problems....hahahahah. Save your money.

regards, Jacques
