I’m making some steady progress with my Islay glaze materials – after a couple of months of frustrating results. The balance of materials is crucial; limestone, limonite / bog iron, quartzite, ash, but at last I’m getting a lovely clear – green glaze, which is streaky when thin, but deep and glossy when applied thickly. I have tried a copper splash to add a break to the background glaze, copper having been mined on Islay in the middle-ages / early modern period. I’m delighted with the results, but I want to expand the colour palette a little.
I am drawn to a splash of blue, to conjure up the sky and sea – such a hugely important set of factors when experiencing the island. There’s also that occasional fragment of blue sea-glass washed up on the shore. I think that next steps may well include a blue splash or two on the tumblers. The cobalt necessary for this, however would most definitely be from far flung quarries, half a world away. but it is possible that artistic license may just have to give me the permission here.
