The silicate in the form of a concentrated solution is crutched or stirred into the soap in a mechanical mixing machine after the completion of the saponification, and it appears to enter into a distinct chemical combination with the soap. While silicate soaps bear heavy watering, the soluble silicate itself is a powerful detergent, and it possesses certain advantages when used with hard waters.
Besides the four great orders of friars, the Trinitarians, though really canons, were in England called Trinity Friars or Red Friars; the Crutched or Crossed Friars were often identified with them, but were really a distinct order; there were also a number of lesser orders of friars, many of which were suppressed by the second council of Lyons in 1274.
Such are Austin Friars, Crutched Friars, Blackfriars and Whitefriars.
Besides the four chief orders of friars there were the Crutched Friars in the parish of St Olave, Hart Street (about 1298), and the Friars of the Sac first outside Aldersgate (about 1257) and afterwards in the Old Jewry.
But no remains exist of the priories of Augustinian canons at Canterbury (St Gregory's; 1084), Leeds, near Maidstone (1119), Tunbridge (middle of 12th century), Combwell, near Cranbrook (time of Henry II.); the nunnery of St Sepulchre at Canterbury (about 110o) and Langdon abbey, near Walmer (1192), both belonging to the Benedictines; the Trinitarian priory of Mottenden near Headcorn, the first house of Crutched Friars in England (1224), where miracle plays were presented in the church by the friars on Trinity Sunday; the Carmelite priories at Sandwich (1272) and Losenham near Tenterden (1241); and the preceptory of Knights of St John of Jerusalem at West Peckham, near Tunbridge (1408).
Roger de Peppart, lord of the manor early in the 13th century, founded the present Protestant church and a house of Crutched Friars.
