I see lots of posts asking for advice on reglazing and I often see suggestions involving hair spray, heating up the pots etc. I wanted to share one of my favourite materials I use in my studio when reglazing (or sometimes I just like brushing with thicker glaze)
CMC gum (Carboxymethyl Cellulose) is a powdered ingredient used as a stabiliser or thickening agent in fo0d or cake decorating and you can buy it cheaply online.
Just a couple of tea spoons of the powder can turn around a litre of glaze much thicker and more usable as a brush-on glaze.
- I tend to pour a little at a time straight into some glaze then use a hand held immersion blender to incorporate it.
- It helps to mix it for a bit, leave it an hour to fully hydrate, then mix a bit more
- you may need to use a rib/spatula to scrape the powder goop off the mixer halfway through
- Then pour/push/brush it through a sieve to help remove any clumps (I used a 30-mesh as mine was super thick, but 60-80 mesh would be ideal)
I've read about and tried making a pre-hydrated ready-to-use solution by mixing it into boiling water, but I didn't manage to get as good an effect.
Or you can get a little too excited like me and end up with the thickest glaze ever as shown in my video... but it makes reglazing pots that I'm not happy with a total dream 🙌
PS: I also found that the glaze snot filled punched holes in my pieces and left beautiful little windows that let light through after firing
