This high-density white plaster\/gypsum powder is specially processed to offer a finer grain, stronger set, and smoother finish compared to standard craft plaster, making it ideal for detailed DIY castings and aromatherapy stone making.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I use this plaster powder to make aromatherapy diffuser stones?\u003c\/h4\u003e\n\u003cp\u003eA: Absolutely! Once set and fully dried, gypsum plaster is naturally porous, which allows it to absorb essential oils and slowly release their fragrance into the air. Simply add a few drops of your favourite essential oil to the finished stone and enjoy a natural, long-lasting scent diffuser.

Full curing and drying to maximum hardness takes approximately 24 hours. Avoid painting or applying oils until fully cured for best results.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is this plaster powder safe to use indoors?\u003c\/h4\u003e\n\u003cp\u003eA: Yes, when used as directed. Mix in a well-ventilated area and avoid inhaling the fine powder dust during mixing — we recommend wearing a basic dust mask while handling the dry powder. Once mixed and set, the material is stable and safe for indoor display and use.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Which moulds work best with this casting plaster powder?\u003c\/h4\u003e\n\u003cp\u003eA: Silicone moulds are the most popular choice for plaster casting as they are flexible, non-stick, and allow for easy demoulding. Plastic and rubber moulds can also be used with a mould release spray. Avoid using cardboard or paper moulds as they may absorb moisture and distort the shape.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What is the difference between plaster powder and gypsum powder for DIY casting?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Plaster powder and gypsum powder are very closely related — both are calcium sulfate-based materials used for casting and moulding.
