About 40 degrees Centigrade. Just add boiling water to make a cup of tea, and the design is revealed within a few seconds as the mug heats up. It fades to black as you finish your drink and the mug cools down again.
People tend to go 'Wow' when they see them for the first time. Sometimes they pour the water back out and in so they can see the colours change again.
No,of course not. Our mugs are totally safe to drink from. (Unless of course you actually PUT cyanide, nuclear waste, et. al. in them). Heat sensitive mugs have been ordered in tens of thousands by big companies for promotions. They wouldn't hand out anything dangerous to their customers, would they now?
There's nothing funny about Anthrax et. al. Aren't you just being really juvenile and tasteless for the sake of it?
Yes. The mugs are as durable as any high quality household mug. Barring dropping them on the floor, they will last for years.
The dishwasher is not recommended. Nothing dramatic happens, but they gradually start to fade.
A quick zap in the microwave is fine. But don't do it for minutes at a time, otherwise the image can blur.
On Poison Mugs, the design is printed under a special black thermochromic coating. This coating becomes transparent when heated, revealing the design beneath. Becuase both the coating is black and the design's background is black, it gives the impression that the design is appearing, rather than the coating disappearing.
IAQs (Infrequently Asked Questions) would be a better abbreviation. One bloke did call and ask whether we would pass his name on to any spam lists, hence the 'FAQ' about mailing lists near the bottom, though.
We charge £9.95 per mug, plus a flat rate p&p charge of £2.95 (in the UK - more for elsewhere) , no matter how many you order. The heat sensitive process is a good deal dearer to manufacture than your average mug, but the effect is well worth it. Remember, there are discounts (and no extra postage) for ordering a few at a time.
Nope. Here only. If you own a shop and want to sell them, we would be delighted to hear from you.
We also sell heat-sensitive ironing board covers. When you pass a hot iron over the model's towel / bikini, it disappears to reveal all beneath. They're made of heat-reflecting metallic fabric (so good for ironing) and cost £14.95 each. The female version features glamorous model/mother/cancer patient Jordan.
We use 1st or 2nd class Recorded Delivery for the majority
of orders. Generally, we put them in the post the next working day after you order.
Bigger orders (8 and over) go via the Parcelforce 48hr service. Somebody has to
be home to receive the package otherwise the postman will put a card through your
door. If the mugs don't arrive within a week, contact
us and we will yell at the Post Office and if necessary, send more.
International orders (outside the UK) go Airmail, which takes a week or so.
Extremely secure. The Poison Mugs website doesn't actually collect your payment details. After taking your order details, we hand you over to our payment partner World Pay who specialise in taking money over the web. Alternatively, you can send us a cheque in the post or order over the phone. Click here for contact details.
