April 23 2026<\/strong><\/p>\n\n\n\n

I was not sure how the vat will over winter in the f\u00e4rberhutte. This winter was especially cold, it went multiple days under -10degrees. I could not even come to hutte to check as the roads were frozen and I could not bike. I opened the vat the fist time on the April 23, and this is how it looked. Rainbow colour shines out! what a surprise.<\/p>\n\n\n\n

PH is low, 8.63 and the vat temp is about 16 degrees. still very cold. The colored things are probably mold, and I see some white mold developping on the side. I scouped out the mold culture o nthe surface, wiped off the white mold on the wall. To prevent mroe mold to develop on the wall, I mixed calk with small amount of water and painted the wall + the back side of the lid. <\/p>\n\n\n\n

Mixed the vat, and surprisingly it makes the hana blue bubble. The ph after mixing is 10.7. not bad. and the color test even shows a lot of blue. surprising!<\/p>\n\n\n\n

Maybe we will have a nice blue season this 2026 summer? it feels like a good start.<\/p>\n","_en_post_name":"over-wintered-vat","_en_post_excerpt":"","_en_post_title":"over wintered vat","_de_post_content":"","_de_post_name":"","_de_post_excerpt":"","_de_post_title":"","edit_language":"de","neve_meta_sidebar":"","neve_meta_container":"","neve_meta_enable_content_width":"","neve_meta_content_width":0,"neve_meta_title_alignment":"","neve_meta_author_avatar":"","neve_post_elements_order":"","neve_meta_disable_header":"","neve_meta_disable_footer":"","neve_meta_disable_title":""},"categories":[9,6],"tags":[],"_links":{"self":[{"href":"https:\/\/nerding.at\/circular_blue\/de\/wp-json\/wp\/v2\/posts\/1925"}],"collection":[{"href":"https:\/\/nerding.at\/circular_blue\/de\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/nerding.at\/circular_blue\/de\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/nerding.at\/circular_blue\/de\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/nerding.at\/circular_blue\/de\/wp-json\/wp\/v2\/comments?post=1925"}],"version-history":[{"count":2,"href":"https:\/\/nerding.at\/circular_blue\/de\/wp-json\/wp\/v2\/posts\/1925\/revisions"}],"predecessor-version":[{"id":1935,"href":"https:\/\/nerding.at\/circular_blue\/de\/wp-json\/wp\/v2\/posts\/1925\/revisions\/1935"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/nerding.at\/circular_blue\/de\/wp-json\/wp\/v2\/media\/1926"}],"wp:attachment":[{"href":"https:\/\/nerding.at\/circular_blue\/de\/wp-json\/wp\/v2\/media?parent=1925"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/nerding.at\/circular_blue\/de\/wp-json\/wp\/v2\/categories?post=1925"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/nerding.at\/circular_blue\/de\/wp-json\/wp\/v2\/tags?post=1925"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
