TIP: Using and Purchasing Copper Sulfate
Safe to Use: Use it Safely!
Remember, Copper Sulfate is still a chemical and toxic to humans if ingested, so make sure you follow safety instructions and read MSDS sheets prior to use. Always wear gloves, goggles and a mask when handling any etching chemicals. Do not touch, inhale or ingest.
Safe to Ship!
For the printmaker who wants to use the Saline Sulfate Etch, getting hold of small (rather than industrial) quantities of Copper Sulfate is easy. I recently ordered a 5lb bag of Copper Sulfate Crystals over the internet. Because it is a low hazard material, the delivery came by ordinary mail services - simple, safe and economical too. No need for the specialist carriers required when shipping traditional printmaking mordants

STRIPPING SOLUTIONS _________________________________________
Orange Zest Solvents Acrylic resists strip off easily with the new citrus-based solvents.
Z*Acryl D*Solve is an excellent product.
"This truly revolutionary solvent was formulated as an alternative to petroleum-based turpentines and thinners. It is made from 100% renewable agricultural resources of soy, corn, and citrus, and is non-polluting, non-carcinogenic, and bio-degradable. Less than a teaspoon will thoroughly clean a large plate. DSolve will even strip dried ink from etched lines." Dick Blick
