I personally like hot coffee and to me mug’s ability to keep drink warm is important. Especially outdoors in poor weather. But in the office too – it’s quite nice to drink warm coffee at a long meeting while others are sipping it cold.
So we decided to run a small test and compare Bogmug to a standard ‘clay’ coffe cup; to a old time porcelain or china cup; to gas station paper cup and finally a good quality traveller’s thermo mug.
Theory – a cup’s ability to keep drinks warm or cold depends on a lot of things, but shortly it comes to two main features:
Testing – we heated up water to 85 Celsius and poured it simultaneously into all ups being tested. We left the cups in the same room for 15 minutes and measured the temperatures, the results were the following:
Comment – It’s no surprise the travellers cup was the best as the design and construction resembles most thermos bottle.
