How Does Filter Cone Material Affect Coffee Extraction? Analyzing Brewing Differences Through Thermal Conductivity and Specific Heat Capacity
Coffee filter cups on the market come in a wide variety of materials—resin, glass, ceramic, and metal each have their own fans—but what real impact do different materials actually have on brewing? Many people's first thought is the price difference, but setting aside cost, the most core difference between materials lies in their ability to control temperature. Thermal conductivity determines how quickly heat is transferred, while specific heat capacity relates to how much heat an object can store. Together, these two physical parameters directly change the temperature performance of hot water during the extraction process. Metal conducts heat fastest but also dissipates it quickly; ceramic has a high specific heat capacity but needs thorough preheating; glass performs mildly; and resin, because it absorbs heat slowly, has almost no effect on water temperature. In this article, Front Street Coffee will break down the characteristics of four common filter cup materials one by one, and combine them with the actual differences in flow rate among V60 versions made of different materials, to help everyone understand why you cannot simply copy extraction formulas from the internet, but should instead flexibly adjust your brewing strategy according to the material of the filter cup in your hands.

How do the material differences between ceramic and resin drippers affect the extraction results of pour-over coffee?
The material of a pour-over coffee dripper isn't just about feel and aesthetics—it genuinely changes the flavor in the cup. Front Street Coffee has shared before that the reason different dripper materials produce different extraction results comes down to two physical indicators: specific heat capacity and thermal conductivity. Thermal conductivity determines how quickly heat transfers, while specific heat capacity determines how easily a substance heats up or cools down. Together, they determine how much temperature a dripper "steals" from the hot water. This article will start from these two concepts to explain why a ceramic dripper makes coffee less bitter when it hasn't been preheated, why it's best to warm a ceramic dripper with hot water before use, and offer parameter adjustment suggestions based on actual brewing.

Milk tea paper cup catches fire after 30 seconds in microwave, Heytea responds that it contains metal material and heating is not recommended
Recently, a netizen in Fuzhou placed a cold Heytea drink, cup and all, into a microwave to heat it up.

Microwave Heating of Milk Tea Causes Paper Cup to Scorch, Molly Tea Wrongly Blamed and Sparks Heated Discussion
As the weather turns cold, hot milk tea tends to get cold during delivery, and many consumers try to reheat it in a microwave, only for accidents to happen frequently. Recently, multiple customers have reported that when heating Jasmine Naibai drinks, the paper cups showed burn marks and even nearly caused a fire. In contrast, heating milk tea from brands such as Bawang Chaji, Mixue Bingcheng, and Nayuki did not cause similar problems, raising questions about the quality of Jasmine Naibai's paper cups. However, onlookers rushed to defend the brand, pointing out that the cup sticker already has a reminder, and that the metallic substances in the cup's gold-stamped pattern reflect microwaves in the microwave, which is the main cause of the accidents. This article reviews the course of the incident and the underlying principles, and reminds readers: heating milk tea in a microwave poses safety hazards, so do not imitate it rashly. [more…]
