I need a bottle of macro-etchant.
5% Nital or iodine etchant would do well.How do you get a bottle of ready-to-use already mixed / made-up etchant? I can't be mixing Nital at home, nor storing the ingredients (nitric acid, methanol)
Could probably mix the iodine etchant at home... The ASME recommended formulation by weight:
- one part of powdered iodine (solid form)
- two parts of powdered potassium iodide
- ten parts of water Due caution, but none of these are going to burn a smoking hole through the floor into the downstairs apartment...
How do you folk go about getting etchant and what do you choose?
The plan is developing weld procedures for steel fabrication companies
- make sure that the conditions are giving good fusion, etc.
