TQS--一個有著悠久傳統的年輕公司公司於1910年在柏林成立，名稱為Deutsch-Englische-Quarzschmelze GmbH。主要生產熔融二氧化矽產品，用於當時年輕而繁榮的化學工業的各種應用。1957年，該公司搬遷到美因茨，並在那裏作為TSL-Thermal辛迪加有限公司（英國）和Jenaer Glaswerke Schott+Genossen（德國）的合資企業管理到1965年。1965年--同時是TSL集團的浩利子公司--該公司將總部遷至威斯巴登，並從那時起以TQS-Thermal Quarz-Schmelze GmbH的名稱經營。從這個時候起，威斯巴登的主要焦點是不斷發展紅外石英發射器和光學石英玻璃製成的組件。公司一貫重視與客戶的密切合作。因此，許多新的發展和改進可以在這些年裏共同取得成功。1988年，整個TSL集團被法國聖戈班集團接管。自2000年起，這家總部位於威斯巴登的公司以聖戈班石英有限公司的名義經營。2009年，在管理層收購的過程中，該公司能夠給自己一個法律上獨立的框架下仍然著名的標誌TQS-Technology Quartz Solutions GmbH-。TQS®漫長曆史上的最後一步發生在2015年初，總部位於法蘭克福的出口公司VS Technology Supply GmbH收購了TQS®100%的股份。今天，沃爾克·施密特先生負責管理。
