Orders can be placed only with valid company details. Contact us with a Chamber of Commerce number and VAT number, and we will verify your details before we process the order.\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eBorax is a sodium salt that you use as a flux for forge welding. When forging Damascus steel, it binds the impurities on the steel surface so the layers bond properly to each other. The powder is white, is made from boric acid and is also known as sodium borate, sodium tetraborate or disodium tetraborate. We supply the anhydrous variant, sodium tetraborate, with the lowest water content of the three common types.\u003c\/p\u003e\u003ch2\u003eUse and application\u003c\/h2\u003e\u003cp\u003eIn the forge, you mainly use borax for forge welding and for Damascus steel. It provides a low surface tension and therefore works well as a flux when soldering.\u003c\/p\u003e\u003cp\u003eOutside the workshop, you can use borax directly or process it as an ingredient. As a standalone product it is used, among other things, as a drying agent, water softener, laundry booster, rust remover, cleaner for air conditioners and clogged drains, and as a household cleaner. As a pesticide against cockroaches and woodworm, it is intended solely for professional pest controllers; do not use it for that purpose yourself.\u003c\/p\u003e\u003cp\u003eAs an ingredient, you will come across borax in flux for welding iron and steel. It is also found in earthenware, ceramics and glass, in some toothpastes and tooth whiteners, and in flame retardants.\u003c\/p\u003e\u003ch2\u003eTypes of borax\u003c\/h2\u003e\u003cp\u003eBorax is a collective name for related compounds that differ from one another in water content.

Small quantities generally cause no health effects. With large quantities the situation is different: inhaling it can irritate the airways, most quickly in children, and swallowing it can cause nausea, diarrhoea or vomiting.\u003c\/p\u003e\u003cp\u003eUnlike many other salts, borax does not cause skin irritation. The European Union does consider the substance a potential health risk, as do Canada and Indonesia. This is because people are regularly exposed to it through food and the environment, which means total exposure can add up. Children and pregnant women are advised to limit or avoid exposure.\u003c\/p\u003e\u003cp\u003eIf you are unsure about an application, consult a professional before using the powder.\u003c\/p\u003e\u003ch2\u003eLegal designations\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHazard statement (H code):\u003c\/strong\u003e H360FD, may damage fertility and may damage the unborn child\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecautionary codes (P codes):\u003c\/strong\u003e P201, P308 + P313\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstruction:\u003c\/strong\u003e obtain special instructions before use; if exposed or concerned, get medical advice\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e anhydrous borax, sodium tetraborate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFormula:\u003c\/strong\u003e Na2B4O7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColour:\u003c\/strong\u003e white\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackaging:\u003c\/strong\u003e 800 grams and 4 kilograms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSales:\u003c\/strong\u003e business customers only, after verification of Chamber of Commerce and VAT number\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Parrot Shopping","offers":[{"title":"4000 grams","offer_id":57979164066175,"sku":"800000163","price":51.27,"currency_code":"EUR","in_stock":true},{"title":"800 grams","offer_id":57979164098943,"sku":"800000164","price":29.6,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0936\/5366\/4127\/files\/borax-poeder-natriumtetraboraat-vooraanzicht.jpg?v=1786655563","url":"https:\/\/parrotshopping.com\/en\/products\/borax-powder-sodium-tetraborate","provider":"Parrot Shopping","version":"1.0","type":"link"}
