Bisque Fire A Cone 6 Glaze On Cone 6 Clay?

[Hanoverian]

Hi, 

I have an unfired pot (cone 5/6 clay) that has had raw Cone 6 glaze (Coyote Alabaster Satin) 
applied to the inside.  Can I fire this raw pot at bisque temp, leaving the applied glaze inside and then fire again at Cone 6 later?

I was going to once fire this pot... but thinking now it would be a better plan to bisque at least a little first since it has some
fairly fragile embellishments.

Hope this makes sense

Thanks!

are you in a hurry to get this one pot finished?  if not, use the same clay in about the same shape, put glaze on both inside and out and slowly fire it to cone 6.  if it survives, you have an answer.  (there is no reason to fire it specially, just include it in a cone 6 glaze fire and let all the pots be slowly fired.)

Probably. It is hard to tell without trying. Sometimes the final results will be different.

 

 

This statement is true for nearly all "can I" questions about trying something different with firing work. Some restrictions apply, void where prohibited.

I can see no issue firing it to bisque then to cone6 but you could also fire to bisque going slow then continue to cone6 in the one firing. If you have no need for the bisque except to refire it seems a waste to let it cool back down.

I often apply ^6 glazes to bisqued items and the put them in a ^04 or ^06 firing if there's space.  This kind-of sets the glaze making it less likely to flake off.  I then fire to ^6 when I've got a full load.

 

Sometimes it works OK, sometimes it's not so good.  Testing with samples will give you an idea, but every firing can produce different results.

Thank you all for your replies and helpful info!

Joel... good idea... unfortunately, I need to apply further glazing to delicate areas after bisque fire. 
Otherwise, it would be great to be able to do both in one.

Thanks again!
