{"product_id":"coffee-mug-color-changing-heat-sensitive-ceramic-gag-gift","title":"Heat Sensitive Colour Changing Coffee Mug","description":"\u003cp\u003eThis Mug from Velleora Home Decor is glazed with a heat-sensitive coating that goes from opaque to clear as hot liquid is poured in, revealing a hidden design that is invisible when the mug is cold.\u003c\/p\u003e\u003cp\u003eThe reveal is the whole gift. Handed over cold it looks like a plain mug; the design only appears once the recipient makes a drink, which makes it a considerably better novelty than a printed slogan they can read immediately.\u003c\/p\u003e\u003cp\u003eTwo designs are offered. The effect reverses as the drink cools, so it works every time rather than fading after a few uses. Hand wash only - a dishwasher will strip the thermal coating within a few cycles, which is the single most common way these mugs are ruined. Avoid abrasive scourers, do not microwave it, and expect the effect to soften gradually over years of use.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHeat-activated colour changing glaze\u003c\/li\u003e\n\u003cli\u003eDesign hidden until hot liquid is added\u003c\/li\u003e\n\u003cli\u003eReverses as the drink cools\u003c\/li\u003e\n\u003cli\u003eTwo design options\u003c\/li\u003e\n\u003cli\u003eHand wash only - no dishwasher\u003c\/li\u003e\n\u003cli\u003eDo not microwave or scour\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Velleora Home decor","offers":[{"title":"Design 1","offer_id":46485637038177,"sku":"SKU_1766368976805_471","price":58.99,"currency_code":"USD","in_stock":true},{"title":"Design 2","offer_id":46485637070945,"sku":"SKU_1766368976805_723","price":58.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0650\/5034\/5569\/files\/CoffeeMugColorChangingHeatSensitiveCeramicGagGift_2.jpg?v=1787768578","url":"https:\/\/velleorahomedecor.com\/products\/coffee-mug-color-changing-heat-sensitive-ceramic-gag-gift","provider":"Velléora Home Decor","version":"1.0","type":"link"}
