JK Adams Charcoal Slate Coasters, Set of 4

JK Adams Charcoal Slate Coasters (Set of 4) Frequently Asked Questions

What are these charcoal slate coasters and what makes them special?

These coasters are crafted from natural Vermont slate in a charcoal color, with a beautifully flaked edge and felt backing to protect surfaces. They serve both a functional role (preventing rings from glasses) and an aesthetic one, adding rugged-elegant style to drink settings.

What are the sizes and material details?

Each coaster measures approximately 4″ × 4″ with a ¼″ thickness, and comes in a set of four. The natural slate is food-safe, backed with felt to protect surfaces, and made in the USA.

Are these coasters suitable for everyday use and what surfaces do they protect?

Yes. They’re designed for everyday use beneath glasses, mugs or small carafes to prevent condensation rings, heat or moisture damage on wood, stone, metal or composite surfaces. The felt backing helps keep the slate from scratching or slipping.

How do I care for and maintain the coasters to keep them looking their best?

Clean the slate by wiping with a soft damp cloth; if needed, use mild soap and water. Avoid harsh cleansers or cutting on the surface (slate may dull knives). Dry thoroughly after cleaning. Because they are stone, avoid heavy impact or dropping.

Can I personalize or engrave them, and are they good gifts?

Yes — JK Adams offers engraving options on their slate products, making them a great gift for weddings, housewarmings or host/hostess sets. The classic charcoal slate finish and handmade USA-made quality make them a standout gift.

What should I check before buying these coasters?

Make sure your surface needs are matched (4 × 4 size works for standard glasses and mugs). Confirm you’re okay with natural stone variations — slate color, texture and edge may vary. Also consider that slate is heavier than typical coasters and may chip if dropped. Always pick felt backing to protect your table.
