In Topic: Qotw: Are Our Expectations Too High?

27 July 2016 - 03:46 PM

I like peoples big aspirations and dreams but if you can't deal with failure then you quickly find pottery is not for you. No problem with people being naive and expecting to make great things before they have learnt anything.

 

I disagree about the internet or young people being the problem these days and the search for instant gratification has always been a human instinct. It has been played on by consumerism and advertising for much longer than the internet.  


In Topic: Mixed My A First Batch Of Glaze

Go team OldPug  :D Keep mixing and melting those rocks Pugaboo.

 

Celia it probably costs more for lowfire glaze ingredients but I can get a 10kg glaze bucket for £8-12 using raw materials when it is £40 and up for premixed. I think cone 10 is cheaper on ingredients but it sound strange that you can't make it for less.

How are you raising the COE of the body without adding soda or potassium? If I remember correct you said they are bad for crystalline glaze. Maybe it was just sodium actually.


In Topic: Replace Frit 3134 With Gerstly Borate

Standard boarx is the only frit I have used, treats me well.

 

Nerd I was thinking soda too but never having used it either I wasn't sure about adding it.

GB seems to change half the sodium flux for magnesium and comes with less silica.

 

You could mix in a bit of feldspar but then your alumina will be shooting up and alter the recipe. The best match may be to use GB with a little extra silica and ignore the changing of sodium for magnesium. Depending what else is in the recipe you could get a little closer swap.

 

Something like 1 frit 3134 = 0.77gb + 0.23 silica
