The metal cold-cast process (also known as "bonded metal is faster and much less expensive than foundry casting of molten metal (lost wax process.) Different metal powders such as bronze, brass, iron, copper, stainless steel, and stone powders can be used depending on the desired effect.

Our marble powder is sourced from an actual marble quary. Calcium carbnonate (art store marble powder) can be useful as a filler. **Q: What is the volumetric measure of the 1lb bag? I know the average density of marble, but I was hoping to know what 1lb of ground marble equates to in³** A: I would estimate that the unopened package is approximately 3 1/2“ x 5“ x 1“. Hope this helps . It’s a bit squishy. **Q: Does anyone know what the end color looks like?** A: If mixed with a clear resin, the color is an off white. **Q: Is this very hard after cured?** A: White marble has been prized for its use in sculptures since classical times. This preference has to do with its softness, which makes it easier to carve. Our marble powder is actual milled "white marble" from the quarry. However, the ratio of marble powder to a bonding agent such as KastEZ Resin determines the hardness of the finished cold cast product. Resin of course is softer than stone or marble, it being a plastic. Thus, the higher the ratio of resin to marble powder the softer the surface (it still is harder than plastic though). So if you are looking for a harder surface use less of the bonding agent and more of the powder. Think of your bonded marble surfaces you have in your house such as a sink top. That top was made with marble powder and resin. That is the hard surface you will achieve with 2 parts resin and one part marble powder. However, you can achieve a harder surface still, with a half and half mix ratio - you are just using more marble powder. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great painting medium. *by on Reviewed in the United States April 14, 2026* Suggested for painters. I use it in my painting by mixing it with gesso when I prime my canvas. It makes for the most beautifully textured surface which massively reduces drying time and creates a gorgeous aging effect. ### ⭐⭐⭐⭐⭐ Works well, but depends on your technique *by on Reviewed in the United States June 8, 2020* I bought this to try doing some faux marble cold casting with resin. I used Smooth Cast 325, then decanted a small amount of the mixed material and added black pigment and drizzled onto the main mixture, then poured into my mold.The results were pretty decent for my first time. I tried adding some gold powder on one just for fun but I didn't quite get the veining I was hoping for.In short, this stuff works well, but try to find some tutorials to learn how to maximize your end product. ### ⭐⭐⭐⭐⭐ Buen producto *by on Reviewed in the United States November 26, 2025* Excelente producto, lo uso en manualidades y me ayuda a mejorar la textura de mi pasta ## Frequently Bought Together - Marble Powder 325-mesh 1-lb (454 Grams) - Artmolds High Grade Stainless Steel Powder - Easy Cold Casting Formula with Polyurethane Resin for Making Sculptures | Home and Office Decors - 1lb/350 Mesh - ArtMolds High Grade Copper Powder - Easy Cold Casting Using Polyurethane Resin for Making Sculptures | Home and Office Decors - 1lb/350 Mesh --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/21609421-marble-powder-325-mesh-1-lb-454-grams](https://www.desertcart.pt/products/21609421-marble-powder-325-mesh-1-lb-454-grams) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-06-25*
