My understanding of gum arabic is it helps with the application of glazes when brushing them on - is that correct? My glazes to date have all been good but I find that when they dry they turn quite powdery, which compared to some of the commercial glazes, is quite significant. So before a firing I have to be really cautious about how I handle them so as to not leave spots where I've removed the glaze with my hands. Will adding gum arabic help with this? Another issue that I've found is that when brushing on the glazes in layers, some of the 'base' layers underneath are removed at the same time, so the final fired vessel looks quite patchy. This also seems to be less of an issue compared with some of the commercial glazes. Again, as far as I can tell from other forums, this seems to resolve the issue. One last thing - Does anyone know what the ratio of gum arabic is to water when mixing it with raw materials?
Thanks in advance for any advice!
