Four lilac, peachy crystalline cups 🐰
As promised here is the recipe, firing schedule & method
***
Crystalline Glaze Recipe :
For 200g of glaze (which roughly would allow me to glaze 4-5 standard mugs for example 3 times on the outside )
Water - 100g
Ferro Frit - 45.03g
Zinc Oxide - 21.37g
Quartz - 8.52g
Wood ash - 3.82g
Titanium Dioxide - 1.14g
- I would like to:
•minimise ingredients as much as possible
• Make better sustainable swaps e.g quartz for recycled wood ash ( as this is a flux and has silica in it, it may work okay, I will test it this time round )
• make glaze less runny, so no need for glaze catchers (never tried these but don’t want too, as their single use) - smaller segments
Firing Schedule :
9 segments
Ramp 1 - 500
C1- 500
Hold - 0
Ramp 2- 500
C1-1000
Hold - 0
Ramp 3 - 250
C1 - 1250
Hold - 0
Ramp 4 - 50
C1 - 1250
Hold - 0
Ramp 5 - 250
C1 - 1000
Hold - 60mins
Ramp 6- 250
C1 - 750
Hold - 15 mins
Ramp 7- 50
C1- 800
Hold - 10mins
Ramp 8- 400
C1 - 400
Hold - 10 mins
Ramp 9 - 9999
C1 - 0
Hold - 0
Method :
Measure out your water & in a separate bowl measure out each individual ingredient, add to water one by one and tick it off of your list ✅ stir well…very very well, with either a whisk, electric mixer or battery powered whisk, sieve glaze mixture to remove any larger chunks, (I recommend a 120# seive for this) & give the mixture one final good stir, your glaze is ready to go!
Apply 2-3 coats of glaze to bisque fired piece, letting each layer dry in between & set aside to dry before the glaze firing
And that’s all 🧚🏽 I hope you have wonderful success growing crystals on your pottery & I hope you love these ones! All my love, Claudia x
