ABSTRACT Milk is a staple food of huge nutritional and national importance, consumed by almost everyone in some form every day. The sheer quantity of milk being processed daily for drinking, for making into butter and cheese and related products, is huge. Perhaps it is the essential ‘everyday’ nature of the industry that contributes to the fact that it is not, and probably never has been, firmly rooted in the public consciousness. It is this paradox — universal knowledge and use of a product and an ignorance of how it is made — that this article seeks to address, through description, following field recording and documentary research, of the four original purpose-built creameries in Wales established by the former Milk Marketing Board, including where possible an historical perspective, an architectural description and an account of the processes. Three of the creameries are still in existence: one currently derelict and two in dairy-related use, but the fourth, now demolished, has proved somewhat enigmatic.

Bwrdd Marchnata Llaeth：威尔士的四家牛奶营销委员会奶油厂

摘要 牛奶是一种具有巨大营养和国家重要性的主食，几乎每个人每天都以某种形式消费。每天加工饮用、制成黄油和奶酪及相关产品的牛奶数量庞大。也许正是该行业的基本“日常”性质导致了它没有，也可能从来没有，牢牢扎根于公众意识中。正是这种悖论——产品的普遍知识和使用以及对其制造方式的无知——本文试图通过描述、实地记录和文献研究来解决威尔士最初建立的四家专门建造的奶油厂。前牛奶营销委员会，在可能的情况下包括历史视角、架构描述和流程说明。
