High quality Coffee Mugs
First of all, a question like this should be answered by an expert in materials science, and I’m not. Bear that in mind when you read the following.
Generally, you should not take it for granted that coffee mugs are oven safe. Quite simply, some are and some are not.
However, high quality coffee mugs produced for the catering industry; especially the white ones with no decor, are normally oven safe. Nevertheless, I will not give you any guarantee.
Basically, coffee mugs cannot be regarded as oven safe, unless the manufacturer have stated so with a stamp underneath or otherwise have published some kind of guarantee, and the manufacturer is a respected and well-known entity within the industry.
A coffee mug isn’t always what it seems. Coffee mugs come in many varieties, are made from different materials, differ in decoration, and so on.
Moreover, coffee, tea, hot chocolate, and other hot drinks commonly served in mugs, are seldom; read never, served at temperatures above 100 ºC / 212 ºF. However, due to competition, special on sale items, and so on, coffee mugs of low quality might not be able to withstand temperatures much higher than this. The reason is simply that manufacturers, or the manufacturers’ customers, want to save a few pennies to gain a market advantage. There might also be a consumer demand for cheap low quality coffee mugs.
Most coffee mugs are made from some kind of ceramic. Others are made from wood, plastic, clay, pewter, steel, and a long list of other materials. Obviously, some of these materials will never be reckoned as oven safe. To keep it simple, I’ll stick to ceramic for the reminding part of this answer, although other materials might be oven safe.
Ceramics commonly found in a kitchen environment includes Earthenware, Stoneware, Porcelain, and Bone china. Of these Earthenware and Bone china are seldom, read never, reckoned as oven safe, although this isn’t completely true as far as Bone china is concerned. Nevertheless, only a complete idiot would use a Bone china mug to make French Onion soup au gratin, cup cakes or any other kind of food.
That leaves us with Stoneware and Porcelain. Both Stoneware and porcelain is normally oven safe, unless decor elements have been added after the finale glaze is applied and the coffee mug is baked in a furnace.
One finale remark needs to be added about coffee mugs made out of thin porcelain. Although these mugs might very well withstand the heat, it’s advisable to ensure that they are not exposed to any other kind of force while hot, e.g. handled without care.when system has no solution which science is the hardest where to learn entrepreneurship how project baselines are established how entrepreneur start a business how much science is in nursing which engineering is for me which device did you plug in how much technology is used daily when product backlog refinement where the london is located when starting up a business when technology and humanity cross reflection solution whose ph is above 7 which tech companies are still hiring why manufacturing in china when engineering colleges start where to project singing voice where system root is the c drive what is the design date in human design who project class 10 how manager really do it reading when project runway season 20 the de whose solution is y csinx who product information why workers unionize how much company match 401k where to move from london where to go from london by train how workers comp settlement is calculated which technology uses a tunneling protocol when business need to formalize the information where from teacher our is when tech companies lie to us what products have titanium dioxide who management of pain when design user interface which science is the most important from where to start teaching english who or what is the third teacher why startup culture is bad which product results from the breakdown of fibrin where startup folder in windows 8 who manufacturer maruti suzuki engine when london falls where to sell tech how business credit cards work where to manufacture makeup which project sekai character are you wh technologies project where design which solution is a homogeneous mixture what science is taught in 10th grade differential equation whose solution is y cx c c 3 who workers health what manufacturer makes jeep how often to maintain muscle how much business insurance cost how far london to ireland how much tech savvy are you how much device time how far will technology advance who business school which london airport is better what is included in a roadmap where product key steam how science works when london was capital of america when solution is simple god is answering what company is enhypen under who entrepreneur definition which manager has won most ucl how many entrepreneurs are in the world where business administration can work how project management works how system in human body how much system 8 powerball whose teaching is in support of education for all who company makes koldfront air conditioners startup who is agent stroud what solutions are isotonic who regulates whom what is the most popular technology used today how long startup repair windows 7 how many solutions calculator how long system restore take how many engineering jobs are there in the us who entrepreneur for capitalist psychologist and economist how much system 7 toto whos london boy about whose forest ncert solutions what product results from this reaction whu business school ranking how company 401k match works whose de when startup repair doesn't work whose project is nlex why equipment maintenance is important burow's solution where to buy where to study engineering where london magazine what is a development milestones why teaching is important what startup costs are deductible which system produces blood cells when technology gets ahead of society who solution recipe for rehydration who technology addiction what system is the liver part of how much business insurance cost when manufacturing overhead costs are where's device management on iphone who set up instagram what management style am i how solution is mixture how many business days how much management reserve why london is the capital of the world
