In Topic: Is This Too Fast To Fire?

Today, 11:08 AM

How thick are your pieces, sculpture or pots? Type of clay used, is it a cleaner firing porcelain or does it have lots of carbon bearing stuff to burn out? Do you run a vent, cram your bisque or is it loosely loaded? Like everything with clay I don't think there is one correct answer, it depends...  If you have problems with pinholes in your glazed wares this has a strong possibility of being caused by either bisquing to fast or not enough venting with the bisque. Pots might not blow up in a fast bisque but carbon needs to burn out.

In Topic: Rotary Glaze Sieve

I second the talisman sieve as being a great time saver. It does take time to clean out the brushes when going from a dark glaze to a clear or lighter one. The rest of the clean up takes a negligible amount of time, like 10 minutes or so max. I have used it with just one brush to cut down on the amount of time spent cleaning them. 


I bought my talisman before this one came out, haven't used the PSH one so can't comment on how well it works but at $50- it's way cheaper. I wonder if you could just buy the adjustable top part with the brush and use your own sieve?

This reminds me of when only the “real potters” were those that fired to ^10 reduction. Times change, attitudes with them. If you are happy with your results then it doesn’t matter what anybody else thinks does it? 

In Topic: Gloss Going Matt

23 March 2015 - 11:39 AM

I plunked the recipe into Insight and played around with increasing and decreasing the ingredients just in case you made an error in the weighing out like you mentioned was the possibility. If you had put  only 10 silica in and 30 spodumene then the Si:Al ratio goes from 8.57 to 6.38 which along with the slow cool could be enough to make a matte glaze. Also, if the error was with the OM4 ball clay the the Si:Al ratio is 6.37 ( 10 silica, 30 ball)


Does it feel like an alumina matte, or a silky / buttery matte?


I would include a test tile with no colour additives as a baseline.


Also, do you need to slow cool if you are going for a gloss?

Hi Babs, it's just a patch of dried mud.  :)
