Ben xyz Posted February 7 Report Share Posted February 7 Any ideas on how on re-create Bertoncello's glaze from the 60's/70's? There was an Antique White (c5) at the studio for a while which was similar, but too expensive for them to continue making. Thanks! Note: Have also posted this question on Glazy as well. Will relay any info possibly found there. Quote Link to comment Share on other sites More sharing options...
Min Posted February 7 Report Share Posted February 7 Looks like a cream breaking brown glaze. Sometimes called cream breaking rust or red or more recently there is a glaze called Folk Art Guild White that is the same type of glaze. High level of tin with a small amount of iron, application is crucial to get the breaking colour. Ben xyz 1 Quote Link to comment Share on other sites More sharing options...

Here is close-up of another Bertoncello piece. https://antiques-international.ch/product/bertoncello-ceramic-vase-square-shape-with-two-hole-handles-by-roberto-rigon-italy/ I've certainly not got a better idea of what's happening, but I really don't understand how that pattern is formed. If it is the result of firing single layer of glaze over a smooth pot I'm really baffled. [Unless it's something really strange like a white crackle glaze leaving behind finger-wipe style colouration.] Quote Link to comment Share on other sites More sharing options...

The colouris the glaze breaking on these areas imo. Ben xyz 1 Quote Link to comment Share on other sites More sharing options...
