Hi Jessica!
I made a few mug toppers which really came out great.. They were bisqued to 04 with just underglaze and a low-fire clear. I did NOT glaze the bottom piece, but did underglaze it. My question is would this be acceptable to just use as is? or do I need to use the low-fire clear on the bottom as well (this means I would have to rebisque at 04). Thats the part that usually catches the steam from the liquid...so I'm guessing I have to use some sort of glaze, correct? and is it OK to just go to 04? Any help you can provide would be great! Thanks

Hi im not a expert but at cone 04 you vlay is not vitrified unless it is an 04 clay. It will absorb water. I would glaze the bottom and fire it on a stilt.

Thank You for your reply! Yes, that is what I thought as well...it would not be vitrified unless it was fired at cone5. I actually reglazed (with Speedball underglaze) the bottom flange and fired to cone5, so all is good! Again, Thank You for your reply! Clayshare is GREAT!

I just made some mug toppers for the first time after watching the “mug topper” class. In the class Jessica glazed the rim on the underside, but does not glaze the part that sits down in the mug. She did say you could glaze all of it and use stilts when firing, Both parts of my ctoppers have texture, so I think I am going to use underglaze when leather hard on the part that sits down in the mug and then wipe it back. After bisque firing I will glaze the top and rim on the underside. I hope this makes sense.
