Every year I make DIY crystal skulls because… why wouldn’t I want my house sprinkled with spooky geology. It’s absurdly easy, wildly satisfying, and yes — you can crystallize basically anything that is pores, doesn’t float, and will sit still long enough. Natural skulls I find on hikes, glazed ceramics, plaster pieces — they all turn into glittering Halloween relics with one magic potion: borax + boiling water + patience. Here’s how I do it!
• Gather materials — a big pot, borax, boiling water, and the object you want to crystallize (skulls, ceramics, plaster, whatever fits).
• Mix your solution — add 1 cup borax per quart of water, heat until fully dissolved.
• Remove from heat — once clear, take it off the burner.
• Submerge your object — gently lower your skull or item into the solution.
• Let the magic happen — leave it 12–24 hours as the water cools and crystals grow. Longer soak = more crystals.
• Release stuck pieces — if it’s stuck to the pot, add a little heat to loosen.
• Dry + display — set on a towel to dry completely.
• Optional sealing — acrylic sealant keeps them longer, but I usually leave mine raw and dissolve them after Halloween.
