In addition to finding out if, or how much, the glaze will run,  the test tiles will let you see what the glazes look like without the reduction that takes place in raku process..  There's a good chance that without that step, they're going to look a lot different than expected - and your student may decide they don't like the results well enough to use it on the pieces they originally planned.

Thank you! I'm hoping our clay tests does fine with the glazes, since the clay is not specifically for raku.

Raku glazes are often high in metals, but that doesn't necessarily mean they'll fume any worse than a regular glaze. I assume the kiln is vented?

Yes, our kiln is vented. I've personally have never done raku firing or used raku glazes.

Do some test tiles and put them on a cookie. A tile (or sacrificial piece) with a large vertical surface will help you interpret how the glaze runs. The only problems I foresee are a runny glaze that goes all over the shelves and an uninteresting result. A lot of raku glazes are specifically designed to become interesting on being thrown into a trash can full of straw, red hot.

“Around cone 04” sounds a little vague. I would trust what the label says, no more, no less. Mayco is not exactly a fly by night operation. It does seem like they say cone 06 is the target for these glazes. Prepare for runs at 04. 

Thank you for the advice! I think my biggest concern was more so regarding any fumes that could result from the firing since our kiln is inside our studio and we often have it running while there's students working in here.

Hi everyone,

A student of mine bought a couple of Mayco raku glazes and wanted to see if she could use them in our studio. We use cone 6 clay (BMIX) here but bisque fire it to 04. I was reading the instructions on the raku glazes and it says that it can be fired to around 04 followed by the raku process. My question is: can we safely fire the raku glazes onto our clay and only fire it to 04 without having to follow through with the rest of the raku firing process since my studio doesn't do raku firings? She is only making sculptural work so I'm not worried about firing the clay fully to cone 6. 

Thanks in advance!
