A good starting point before committing to the full Fabric or Paper kits.\u003c\/p\u003e\n\u003cp\u003eCyanotype is one of the earliest photographic processes, developed in 1842 — the same chemistry behind architectural blueprints. You mix the two-part sensitiser, coat the included watercolour paper, place objects or a printed transparency on top, expose to sunlight for a few minutes, then rinse in water. The exposed areas turn deep Prussian blue; the blocked areas remain white. No darkroom needed.\u003c\/p\u003e\n\u003cp\u003eIncludes sensitiser, postcard-format watercolour paper (cold-pressed, acid-free, no optical brighteners), foam brush, transparencies for inkjet printing, and illustrated instructions in four languages. Assembled in the Netherlands. Not recommended for under 12s.\u003c\/p\u003e","brand":"PAR","offers":[{"title":"Default Title","offer_id":55353786696056,"sku":"CKPC01","price":22.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0528\/7388\/7910\/files\/cyanotype_postcard_kit_diy_sun_print_blueprint_10x15cm_art_kit.jpg?v=1762619601","url":"https:\/\/www.bradburyart.co.uk\/products\/cyanotype-postcard-kit-diy-sunprint-blueprint-kit-for-artists-creatives","provider":"Bradbury Art","version":"1.0","type":"link"}
