To file an Ink Plus Price Protection claim, start by gathering your purchase documentation, including the original item receipt and your Ink Plus credit card statement showing the purchase. Next, find proof of the lower price you discovered, such as a flyer, advertisement, or online listing. Contact the benefit administrator, usually through your credit card's customer service line or dedicated benefits portal, to report the claim. You will likely need to fill out a claim form detailing the item, its original cost, the lower price found, and submit all supporting documents. Keep in mind that claims must typically be filed within a specific timeframe after purchase, often 60-90 days. The issuer will review your claim and, if approved, reimburse you for the price difference.

For large pours, deep pour epoxy resins are highly recommended due to their specialized formulation, designed to minimize heat build-up and cracking that can occur with standard epoxy resins. These resins allow for pours of up to 2 inches in a single pour, providing a longer work time to facilitate bubble release and perfect leveling. Brands like EcoPoxy Liquid Plastic and MAS Deep Pour are popular for their clarity and low-viscosity properties, making them ideal for large projects like river tables or casting. It's important to follow the manufacturer's guidelines regarding mixing, temperature, and curing times to ensure optimal results.

Iron gall ink, historically acclaimed for its deep, rich black color, owes its use to many famous documents throughout centuries. Its formulation, primarily from gall nuts, iron salts, and gum arabic, reacts to create a permanent bond with paper fibers. However, the stability of iron gall ink can be a concern; it is notorious for its acidic nature, which, over time, can corrode the paper it's written on, leading to potential loss of material. RH (relative humidity) levels significantly affect its longevity. Under proper archival conditions, documents inked with iron gall can be preserved for longer periods. Nonetheless, its acidic properties necessitate careful conservation techniques. Therefore, while iron gall ink has a historical legacy of permanence, its stability is contingent upon environmental conditions and the chemical composition of the specific ink formulation used.
