Sedan l\u00e4nge har jag varit p\u00e5 jakt efter den vita h\u00e5rdgrunden – oftast har jag d\u00e5 experimenterat med pigmentblandningar, vax och mastix. Problemet med pigmenttillsatser i h\u00e5rdgrunden \u00e4r att de (oftast metallbaserade) vita pigmenten p\u00e5verkat grundens h\u00e5llbarhet mot syran. Alternativet \u00e4r rent transparenta grunder som fungerar bra om man etsar pl\u00e5ten samtidigt som man ritar f\u00f6r att slippa ljusreflexer som f\u00f6rsv\u00e5rar arbetet.<\/p>\n

Tills nyligen har vi rengjort och avfettat kopparpl\u00e5tarna med lacknafta och t-sprit, en on\u00f6dig och skadlig nittonhundatalsvillfarelse. Numera har vi \u00e5terg\u00e5tt till att avoxidera pl\u00e5ten med vin\u00e4ger och saltl\u00f6sning f\u00f6re avfettning med krita – en b\u00e4ttre metod och f\u00f6rmodligen den man anv\u00e4nde redan innan Rembrandts tid. Ett h\u00f6rn i verkstaden bredvid vattenhon har \u00e5ter befolkats av burkar med slammad krita och stanken av vin\u00e4ger. Detta nygamla element i verkstaden f\u00f6dde en id\u00e9 h\u00e4romdagen – det m\u00e5ste varit den naturligaste sak i v\u00e4rlden att ta penseln med slammad krita och vitmena den nygrunderade etspl\u00e5ten!!!<\/strong> S\u00e5 naturligt till och med att man inte ens nedl\u00e4t sig att dokumentera eller nedteckna tillv\u00e4gag\u00e5ngss\u00e4ttet. (Den enda referensen till n\u00e5got liknande hittar jag i Ernst Bergers kommentarer till De Mayerne-manuskriptet fr\u00e5n sextonhundratalet – d\u00e5 med blyvitt ist\u00e4llet f\u00f6r krita)<\/p>\n

Jag tror att man gjorde ungef\u00e4r s\u00e5 h\u00e4r:<\/p>\n

\"\"<\/a><\/p>\n

Reng\u00f6r pl\u00e5ten som vanligt omv\u00e4xlande med slammad krita och avoxideringsmedel (\u00e4ttiksprit, vatten och koksalt).<\/p>\n

\"\"<\/a><\/p>\n

Grundera sedan pl\u00e5ten som vanligt med h\u00e5rdgrund.<\/p>\n

\"\"<\/a><\/p>\n

Pensla sedan f\u00f6rsiktigt slammad krita ovanp\u00e5 h\u00e5rdgrunden. F\u00f6r att f\u00e5 kritslammet att sprida sig j\u00e4mnt \u00f6ver pl\u00e5ten gnuggar man in lite saliv p\u00e5 ytan. (Fink\u00e4nsliga personer kan anv\u00e4nda oxgalla)<\/p>\n

\"\"<\/a><\/p>\n

L\u00e5t kritan torka.<\/p>\n

\"\"<\/a><\/p>\n

Nu kan man rita upp motivet – se till att n\u00e5len g\u00e5r \u00e4nda ned genom h\u00e5rdgrunden.<\/p>\n

\"\"<\/a><\/p>\n

Kritgrunderingen sitter ganska bra och g\u00f6r inget som helst motst\u00e5nd n\u00e4r man ritar. Naturligtvis skavs den av vid upprepad ber\u00f6ring. (Lite gummi arabicum skulle kunna tills\u00e4ttas f\u00f6r en h\u00e5llbarare yta.)<\/p>\n

\"\"<\/a><\/p>\n

Sk\u00f6lj eller borsta av kritgrunderingen…<\/p>\n

\"\"<\/a><\/p>\n

…och etsa.<\/p>\n","protected":false},"excerpt":{"rendered":"
