Now, saggars are mainly used to create a &#8216;microclimate&#8217; in the kiln, where smoke, vapors, and gases are trapped. These can have an effect on the workpieces. You can fill it with various materials: salt, metal oxides, sulfates&#8230; each material gives specific effects. It is best not to place a saggar in an electric kiln: the smoke, gases, and vapors are harmful to the heating elements.<\/p>\n<\/div><a href=\"https:\/\/cursist-courses.com\/en\/woord\/saggar\/\" class=\"meer-info-link\">More information ><\/a><\/div><\/div><div class=\"woord-item\" id=\"saggar-fire\" data-woord=\"saggar fire\"><div class=\"woord-header cursist-woord-header\" onclick=\"toggleWoord(this)\"><span class=\"eael-advanced-accordion-icon-closed\"><i aria-hidden=\"true\" class=\"fa-accordion-icon fas fa-plus\"><\/i><\/span><span class=\"eael-advanced-accordion-icon-opened\" style=\"display: none;\"><i aria-hidden=\"true\" class=\"fa-accordion-icon fas fa-minus\"><\/i><\/span><span class=\"woord-titel\">Saggar fire<\/span><i aria-hidden=\"true\" class=\"fa-toggle fas fa-angle-right\"><\/i><\/div><div class=\"woord-content\" style=\"display: none;\"><div class=\"woord-uitleg\"><p>See <a href=\"https:\/\/cursist-courses.com\/en\/woord\/smoke-firing\/\">Smoke firing<\/a><\/p>\n<\/div><a href=\"https:\/\/cursist-courses.com\/en\/woord\/saggar-fire\/\" class=\"meer-info-link\">More information ><\/a><\/div><\/div><div class=\"woord-item\" id=\"sgraffito\" data-woord=\"sgraffito\"><div class=\"woord-header cursist-woord-header\" onclick=\"toggleWoord(this)\"><span class=\"eael-advanced-accordion-icon-closed\"><i aria-hidden=\"true\" class=\"fa-accordion-icon fas fa-plus\"><\/i><\/span><span class=\"eael-advanced-accordion-icon-opened\" style=\"display: none;\"><i aria-hidden=\"true\" class=\"fa-accordion-icon fas fa-minus\"><\/i><\/span><span class=\"woord-titel\">Sgraffito<\/span><i aria-hidden=\"true\" class=\"fa-toggle fas fa-angle-right\"><\/i><\/div><div class=\"woord-content\" style=\"display: none;\"><div class=\"woord-uitleg\"><p>Sgraffito is a decoration technique.
